The 1994 Federal Crime Bill and Assault Weapon Ban did not help the subsonic cause, either, as threaded barrels on semi automatic rifles made them subject to the ban.
Unfortunately, the round was trademarked by SSK and other manufacturers were unable to manufacture barrels or even brass and dies for the round. By varying the load, lighter bullets could be fired at supersonic levels with the power of the Soviet 7.62 x 39 or used with heavier bullets at a subsonic level for use with a sound suppressor. Jones formed the brass from 221 Fireball cases expanded to take a. The 300 Blackout round has its roots in the 300 Whisper cartridge designed by JD Jones of SSK Industries in the early 1990s. Shooting 300 Blackout Ammo with a Suppressor.
Subsonic rounds with suppressor how to#
I can also see where Trail Boss would serve very well in teaching a new shooter how to handle a big game rifle, without the report and recoil associated with the full house loads, especially in those big guns.Įditor's Note: This article is from the November 2016 issue of Gun Digest the Magazine. Perhaps this powder would serve as a good reason to cast some good, old-fashioned lead bullets, and get back to roots. can all be loaded with Trail Boss to obtain subsonic results, but it’s going to take a bit of experimenting to see which bullets will perform best in your gun. I’ve seen published data that indicates that a. You can reduce that maximum load by 70 percent for a safe starting load, and work up toward that maximum figure if you choose. This will be your maximum (volumetric) load, though the pressures will be significantly lower than that of smokeless powder. Fill the case to that point with Trail Boss, and then weigh it on your scale. Here’s the loading process according to IMR: Pick a bullet and a seating depth, and carefully mark the outside of the case where the base of the bullet will sit. Nope, ammo was good, but the problem reared its ugly head again when trying the can. Puzzled, I asked him to switch out the can and the brake to see if something was wrong with the ammunition. His bolt was sticky on the upstroke, and I could see flattened primers. After a full day of shooting, Nate decided to swap out the brake for the can, and immediately noticed a change in point of impact as well as the warning signs of high pressure. I saw this for the first time down at the FTW Ranch in Texas, shooting next to a great guy named Nate who had a sweet 6.5 Creedmoor, threaded for both a muzzle brake and a suppressor. Just as a longer barrel will invariably generate a higher velocity than a shorter barrel, all things being equal, the addition of a suppressor has generally shown to increase the velocity of a given load compared to a naked muzzle. Well, I’ve done some playing around, and I believe that in the handloading world, we need to take suppressors into consideration when developing a load. The installation of a suppressor on the end of your rifle undoubtedly cuts down the decibels, but what does it do to your ammunition? What effect does it have on the pressures generated, and the trajectory curve of the bullet? I wear ear protection at the range - sometimes combining two types - and probably should while hunting.
Subsonic rounds with suppressor pro#
Personally, I have ringing in my ears from too many years of exposure to gun fire (nobody wore ear pro when I was growing up) and from decades of playing in loud rock bands (louder is, in fact, better). Unfortunately, they’re not yet legal in all states - here in New York State, for example, where fun is illegal and smiling is a misdemeanor, they’re definitely out - but it sure is nice when the fella next to you at the range has a can instead of a brake. “Quiet on the set!” People’s ears are tired of the loud report of rifles, and here in the States, we’re finally making a larger move toward embracing rifles equipped with a suppressor. Other than certain rounds specifically designed to work in conjunction with a suppressor, handloading for a gun outfitted with a can can be challenging… but not impossible.
