Remington 40 S&w Ammunition Golden Saber Gs40swbb 180 Grain Jhp Review
Much of my shooting in contempo times has been with the shotgun, more peculiarly the trap gun — one yr I spent 50 Sundays shooting the clays and only lousy weather prevented my going out the other two days.
One 24-hour interval not long ago, though, I read with renewed interest an article in a recent Gun Digest by Field & Stream'south gunscribe, Warren Page, called "Half-Minute Rifles." In information technology I learned that Remington had a centerfire burglarize available, guaranteed equally to accuracy. My ears perked up, my interest increased, and I knew I'd take to take one of 'em! Afterward much hard idea on quotient choice I ordered a 40-XB heavy barrel model in standard 6mm Remington caliber, with a twist of i–10″.
I was, of course, impatient to have the rifle in my hands as soon as possible, just considering the forty-XB is a special social club burglarize it takes time — in my case it was close to 8 weeks.
Specifications
The forty-XB tin can besides be had with a light or "standard" barrel. The heavy butt model weighs in at 111⁄4 lbs., less sights, the standard is xi⁄2 lbs. lighter. Both barrels are about 271⁄4″, and for some $20 actress, stainless steel barrels can be had. They're recommended, by Remington, for such hotter cartridges as the 7mm Rem., 30–338, etc., and they will too requite increased barrel life for the 6mm Rem. and 22–250. This is something for the varmint hunter to consider.
Most 40-XBs supplied are single shot; repeaters tin be had, again for an actress $20, in cartridges upwards to the 7.62 NATO, better known as the 308 Winchester. The SS mode has a slight border in accuracy commonly, the action being stiffer considering in that location is no weakening cutting-out through the bottom of the action and stock.
Ane other pick is a $twoscore-extra trigger with a 2-oz pull, for bench-residue and target shooting. Information technology is generally considered also light for field use. However, the trigger on my 40-XB can exist adjusted downwards to about 8 ounces, with safe, and information technology's a joy to employ.
Every Remington 40-XB, before it leaves the factory, must fire three 5-shot groups at 100 yards, these not to exceed a sure accuracy standard for the cartridge being fired:
Exam groups and loading data are furnished with each rifle, the targets with my rifle averaging .47″, well nether the .sixty″ maximum average immune. Interestingly, these groups were fired with custom made bullets, not manufactory! Whether this will keep now that Remington offers match grade bullets in 22 and 6mm (the Ability-Lokt stuff) is moot. Note that Remington doesn't guarantee that the user of their twoscore-XB rifles will obtain the same accuracy shown by their test targets, and in watching some reloaders at work I tin can well see why.
All 40-XBs have scope blocks fastened, just some short target type scopes, at to the lowest degree, are too short to reach the bases. My 10x Unertl Varmint scope wouldn't fit. The base separation is ten.half-dozen″ instead of the older 6.8″ or vii.ii″ dimension, with 1 base on the barrel and the other on the receiver bridge. The receiver ring, likewise tapped, comes sans base of operations, and would allow a vii.2″ separation. The longer target scopes present no problem, of course. The 10.vi″ separation has an advantage; it takes vi clicks instead of four to equal one MOA (1″ at 100 yards), giving more than precise impact adjustment.
The walnut stock is of target type, the wood plain and direct grained for strength. Barrel and action are manus-bedded, with the barrel free-floating. A barrel bedding device at the forepart end of the stock controls tension between barrel and fore-end, and can too exist used with electric bedding devices. The underside of the stock has a rail inletted flush with the wood, permitting aligning of the fastened front end swivel and handstop, designed for target shooters. The handstop is easily removed for field or bench shooting.
The Cartridge
The 6mm Rem. is zero more than the 244 Rem., given a new name, dissimilar bullet weight and a modify in barrel twist. To become a little farther back, the 244 came from the 257 Roberts, which start saw the light of 24-hour interval using the onetime tried-and-true 7×57mm Mauser example. The bullet diameter is hardly new either, equally information technology dates back many years, both here and away. You never heard of the 6mm Lee Straight Pull rifle?
The 244 Rem. and the 243 Win. came out about the same time, just the 244 lost the race rather early when it was plant that the twist used, 1–12″, wouldn't stabilize bullets of 100 grains or heavier if spitzer pointed. The 244 was kickoff loaded with 75- and 90-gr. bullets while the 243 was bachelor with 80- and 100-grainers. With the 243'south 1–10″ twist no troubles were had with 100-gr. sharp pointed bullets. Remington had looked on the 244 as mainly a varmint cartridge, but the public found the 243 a pretty good deer cartridge, and so much and then that 250–3000 and 257 Roberts sales hit rock lesser every bit a effect. Regrettable, too, for both loads make darned fine cart ridges when reloaded.
Remington finally saw the low-cal and changed the twist of the 244 to 1–x″, but for some reason they never did say much when this was washed. Probably also tardily to do much skillful anyway. With the introduction of the Remington 700 rifles a "new" cartridge, the 6mm Remington, also made its appearance. There are no specification differences between the 244 and the 6mm Rem., but reloaders should reduce the 244 charges a flake before using them in the 6mm Rem., if only considering of the faster twist of the latter.
6mm cartridges were originally loaded only with 100-gr. bullets, but late in 1965 an 80-gr. loading was appear. Pleasing news to the non-reloading varmint hunters.
Sighting Equipment
Considering my Unertl wouldn't work. I snapped up a B&L 6–24x telescopic when it was offered at an attractive price. It does add to the weight and bulk of the burglarize no trivial bit, only then this isn't a burglarize anyone would want to bear in the field for any dandy distance.
This B&L variable is a great work of art, and optically won't take a backseat to anything, but in that location is room for comeback, mainly in the method of adjusting parallax. The Parallax Aligning Selector Ring, as B&L calls it, moves the objective (forepart) lens elements back and forth. The higher the power setting the more precise this aligning must exist. If one makes an adjustment at low ability and the scope is then zoomed to high power it will be out of focus, so always adjust for parallax at the maximum power setting y'all intend using.
The variable-ability aspects of this B&L scope give it advantages over fixed ability scopes. You can, for example, seemingly dial away mirage past lowering the power setting. The mirage is still at that place simply it isn't every bit noticeable. The glass can also be used as a spotting scope.
Reloading
Before the burglarize arrived several different makes and weights of 6mm bullets were ordered, along with 100 unprimed cases, 40 factory loads with 100-gr. bullets, and a set of RCBS neck sizing dies. In a burglarize mainly to be used for target work in that location isn't much sense in getting a full length sizing die. Resizing is also easier, as only the cervix is worked. Every bit of at present some cases take been reloaded 20 times and notwithstanding sideslip easily into the chamber.
The unprimed cases were beginning trimmed lightly on a Forster trimmer to brand the mouths smooth and fifty-fifty — most looked equally if they had been manufactory trimmed with a dull hacksaw, one with several teeth missing! This seems to exist a mutual state of affairs with all makes of primed and unprimed brass, non an exception. All cases were chamfered, and then primed with Remington large rifle primers. Alcan primers were too used subsequently, but my shooting could detect no divergence between the two, which speaks rather highly for a newcomer to the rifle and pistol primer field.
All loads were assembled on a Hollywood Senior Turret Tool, a product I can't praise enough. Workmanship is height notch, equally it is on all Hollywood tools, something that seems to exist disappearing from the American scene. A Hollywood micrometer powder mensurate was as well used throughout, and it performed without a hitch. No loads were weighed, though the measure was starting time set using the big Ohaus scales, a fine motorcar but rather too large and bulky to take afield.
Bullets
6mm bullets are bachelor in a large array of types and weights. sixty, 70, 75, 80, 85, 90, 100 and 105 grain sizes, and hollow signal, spitzer, semi-pointed and round-nosed, in flat and boat-tail design, are offered. All signal and base of operations types aren't available in every weight, of class.
Aside from the new Remington Power-Lokt bullets, there are no manufacturing plant 6mm friction match course bullets on sale. Gardiner of Rockford, Sick., now specializes in 6mm bullets, match and hunting types, and Col. Hollidge is well known for his match bullets, 6mm as well as 224, etc.
My 40-XB was factory tested with Crawford Hollidge (Marstons Mills, Mass.) bullets, then a supply of these was ordered. These are soft swaged, hollow pointed and run virtually 70 grains. Later on some heavier Hollidge bullets were likewise purchased.
Shooting
My first groups were fired, subsequently sighting in, with mill 100-grain ammunition. Information technology would exist a gross understatement to say that accuracy left something to be desired, for the final 3 five-shot groups averaged about 1½".
However, equally it was about 15 months since I had washed any serious rifle shooting I laid role of the blame on being out of practice. Such didn't prove to be the whole case though, because afterward I had become used to the rifle and shooting from a demote over again, groups with the other box of factory loads didn't improve much, going about 13⁄8″ average for four groups.
After all cases had been fire-formed I began loading and shooting in hostage.
Without a doubt the best shooting load was the i used at the manufacturing plant for testing accuracy, i.e., twoscore.5 grains 4064 and the 70-gr. Hollidge soft swaged bullets. This load averaged .380″ for a series of groups.
It became credible that the lighter weight bullets were the shooters, because for the well-nigh part anything over 75 grains didn't perform well. Too that 4064, combined with lite bullets, gave the best accuracy.
I similar boat-tail bullets, but the Sierra 85-gr. BT simply won't shoot in this 40-XB, groups running effectually ane″-1¼".
Remington has two new 6mm bullets on the market — on the market if you lot can find them, that is! 1 is a hunting type, the other target way, both fourscore grains.
So far the just 1 that I accept had a take chances to shoot has been the hunting bullet. This is rather odd looking in that information technology could, in all truthfulness, be called a total metal-jacketed hollow point, with a dimpled lesser! How does that grab you?
The nose of the jacket is folded over and in and, looking closely, you'll see v cuts in the nose for quick expansion. Practise they shoot? You're darned right they do. The first load, using 40 grains of 4320, gave a ane⁄2″ group. Going up and downward (very little up, though) in ½-gr. jumps neither hurt nor helped group diameter. With its small diameter hollow bespeak, this should be a apartment-shooting bullet.
The Norma 75-gr. HP bullet shoots well as well, though non quite as good as the Remington. 40 grains of Norma's No. 203 gave an boilerplate of about 3⁄4″, and I finally settled on the Norma recommendation of 42.3 grains of 203, with groups wavering between v⁄8″ and eleven⁄xvi″.
Of interest to me was the velocity consistency of the various loads. Some were markedly better than others. Lowest variation came with the lxxx-gr. Remington bullet ahead of 40 grains of 4320 — a mere eleven fs. 35 grains of 3031 with the 80-gr. Speer was almost as practiced, xix fs. Least consistent was the load using the lightweight 60-gr. Sierra — 89 fs. Remington'due south factory load varied only 30 fs, expert results with machine-loaded ammo.
Odds & Ends
I could accept decreased the xl-XB groups, I imagine, by sorting cases for uniform capacity, checking bullets to meet that they weren't out of round, and other tricks of the trade that the serious benchrest shooter has up his sleeve. However, I was more than concerned with doing things as the boilerplate reloader would — loading proficient ammunition without existence a perfectionist nearly it. As far as the results are concerned I'one thousand more happy with the outcome.
One affair I did do that helped maintain bore condition was to clean the barrel with Jim Brobst's J-B Compound subsequently every shooting session. This is a paste-similar very balmy abrasive which rids the diameter of any fouling. A little bit really makes the bore smooth and shiny, but it isn't at all damaging to the diameter. All traces of it, of grade, must be re moved before shooting.
