[QUOTE="waveslayer, post: 3037431, member: 46202"] The issue is those bullets are misleading with the name. You will want a heavier bullet to get to the Subsonic ranges. That bullet is made for supersonic loads but will expand at lower velocities that you will get out of a 300BO. look at the 200 grain bullets for real subsonic loads with a 300BO. Warning, do NOT go off sound or speeds!!!! you will need to test each load for key holing! otherwise you will have a baffle strike and you get to blow up a can, expensive mistake. Get a good Chrono, borrow one and then test at 100 yards or 50 or key holing. You will be surprised at how easy it is to not stabilize a bullet and get a baffle strike. AA1680 is good for 16" barrels I use a 200 Norma for my 8" barrel, but did a lot of testing to eliminate any key holing. all using 220 gr bullets [/QUOTE]
