![]() These heavy bullets are especially useful when running a suppressed firearm. This is a large round that performs surprisingly well in a shorter barrel for pistol or short-barreled rifle configurations in a subsonic load for hunting purposes as well as personal defense.Īlthough limited by range, out to 150 yards there are many different loads available from supersonic 300-grain spitzer bullets to heavy 550-grain loads that travel at subsonic velocity. One of the more exciting calibers to emerge in recent years for the AR platform has been the 458 SOCOM. and be subsonic, and it would generate 650 foot-pounds of energy.Ī. 44 magnum could use a 300 grain cast lead bullet at 1000 f.p.s. That might help with stability and accuracy and retaining velocity at 100-200 yards.Ī. The longer cases of a true rifle-caliber lever action round allow for much heavier bullets, and possibly even a pointed-tip (polymer tip for nose-to-primer safety) bullet with a streamlined ogive on the front end and a boat-tail base on the back end. ![]() Flat base, and wadcutter or semi-wadcutter nose. It would also demand that, to maximize bullet weight in a short of a length as possible, that the. Case length and SAAMI overall length limits will put an upper limit on how big of a bullet you can load in a. 44 magnum caliber, but that round has a much shorter case than the. ![]() Specialty ammo, or handloads, can feature bullets up to 300 grains in. 44 magnum normally uses a 240 grain bullet, which is in the same ballpark as what the. 300 Blackout with 220 grain subsonic bullets would give you. But you would want a lot more foot-pounds of energy on target than a suppressed. The reason I'm asking all this is that I am thinking about big-bore lever action hunting rifles with threaded muzzles and used with subsonic ammo for a really quiet hunting rifle in the woods or where your expected shot is less than 100 yards and you are confident you would not be called on to take a shot over 150 yards. 45-70 can be loaded a few hundred FPS faster for any given bullet weight, so that means the bullet has more revolutions per minute, and faster RPM means that a slower twist rate can still stabilize the bullet? One has a normal, standard twist rate of 1:14 (SOCOM) while the other has always used, successfully, 1:20, even though the modern trend is to make new guns with 1:18. If 1:20 has always been (for 130+ years) good for 400 grain bullets, and it seems to work fine for 500 grain bullets too (from anecdotal evidence), would it be good for bullets a little heavier (600 gr.) and significantly slower (1040 f.p.s. ![]() 45-70 load features a 405 grain lead bullet at about 1900 f.p.s., and the normal twist in those barrels has always been 1 turn in 20 inches. In comparison, the "standard" historical. What if you wanted to optimize the rifling twist rate just for the super-heavy bullets at slow speeds? Would that mean you'd want 1:10 or 1:12 or something like that? 458 bullet weights and velocities in the SOCOM round is 1:14. I hear that the best all-purpose twist rate for all. Bowers has one and Wilson has one, and they're over $1000. At least a couple of silencer manufacturers make cans for the. ![]() 45 ACP would not be strong enough to handle the pressures of the. How about the cans? I assume that a suppressor made for a. Has anybody done a bunch of market research on what's available? 600 grain slug with an initial velocity of 1000 f.p.s.)ĭoes anybody here have experience with a. But I'm only concerned with the subsonic loads. (300 grain bullets are more common, and with these the velocity is nearly twice the speed of sound. 458 SOCOM, when loaded with 600 grain bullets. I hear that there's a round that's made for AR pattern rifles (using standard lower receivers) that is made for suppressed shooting with much bigger bullets than the. ![]()
