I shoot mine in 4 different cals. 6.5X47 Lapua with a 26" barrel, 338BR with a 17" barrel, .338 Lapua mag with a 26" barrel and 12.7X48 (510 whisper) with a 22" barrel. I use one suppressor for the first three barrels and a dedicated can for the 510. If you want a short 50 for tossing subsonic BMG bullets or supersonics with lighter bullets this is the one to have. It suppresses very well, has no concussion to wear you out, recoil is low and you can choose to shoot subsonic heavies like the 650gr BMG types or 750-800 gr AMAX etc as well as the ability to spit out a 650gr BMG type at 1300-1400fps or a 300gr hunting slug at 2300fps. My rifle with a Nightforce 5.5X22-56 and the 510 suppressor weighs in around 17lb. In the pictures below, the flat dark earth rifle belongs to a friend. I did his 510 barrel and suppressor so its just like the one I have. The pic of the green rifle is mine with some loaded APIT ammo, the shot of the plate with a penetrator stuck in it is from an APIT that we shot at a piece of 5/16 plate at 260yds. It made it most of the way through as you can see. The incendiary charge goes off as well when hard targets are hit.
The last shot is a couple early development loads with cast bullets of 450gr compared to the APIT bullet load.
Not too far off topic but it is a 50 with a 22" barrel....
