I recently got this to see how quiet I could get subsonic ammo



It was quieter than offers I've made with 12" barrels but not really quiet enough for one job I need it for so built a 22" Model Seven which is much quieter

I wanted to use it for a muzzle brake test so shot some Hornady 250 FTX ammunition through it to get the velocities, I was very impressed with its accuracy



Here is the video I made, its difficult to reduce the recoil a lot with the 450 & its heavy slow projectile especially with the small amount of powder it uses.

I have shot a few animals with it using the Cutting Edge & Lehigh pistol/subsonic projectiles, it works extremely well, a big step up from the 30 cal

Good stuff!!!

I "hate" Brakes for the blast and noise they create. Im running a KAW Valley Linear Comp.

My "super" load is a load of aa9 and a 260g HP from Barnes @ 2350 fps. (Warm load)
My hunting load is my cast Lyman 457122 Gould 330g HP and 5744 powder at 1600 ish fps
My sub load is a 457121 Bullet cast 20:1 running 450grs ontop of some Herco for 1170 fps and 1010 fpe.

ALL loads ahoot very well. The Super is sub 1" @ 100 the Gould is under 2" @ 100 and the sub is under 3" @ 100 but mostly touching @ 50!

Good shooting.

I've been using 400gr cast bullet over TB, getting 1000fps with single digit SDs. Accuracy is good and it is very, very quiet.

Good to know. Haven't tried TB yet in the BM but used quite a bit when I was loading 45-70 rounds.
