[QUOTE="azsugarbear, post: 1379256, member: 4809"] I have run a 300 Blackout (actually 300 Whisper in my case) with a can for 10 years now. I have an adjustable block on my AR platform so the rifle will cycle both with super and sub-sonic. Over time, the rifle has become a dedicated suppressed rig. This rifle is super quiet with the sound of the action cycling a new round being much more 'noisy' than the round leaving the muzzle. It is very quiet. When I first started tinkering with this round, there was no commercial ammo available. I reloaded using the typical formulas: fast pistol powders with the 208 A-Max or the 230 Sierra Match. I never tried commercial ammo, because I had my loads down before they became available. Couple of things to keep in mind: (1) Your sub-sonic load at 1000 ft elevation, may well be trans or supersonic at 6000 ft elevation - so load down around 1,000 to 1,050 fps for something to handle all situations; (2) rifle bullets do not expand well below 1,800 fps - so go with a premium bullet made to expand at the lower velocities of the 300 BO such as Corbon, Outlaw, Reapr, Lehigh, etc.; (3) in terms of accuracy and ballistics, think more along pistol caliber, rather than rifle. The 300 BO is a very versatile round. It is not a "do it all" round. Can it take a deer at 200 yards? You bet. But where it really shines is as a hard-hitting subsonic round. [/QUOTE]
