6 Creedmoor w/ 6.5 Creedmoor Lapua brass

[DaveMarine1]

Has anyone tried the combination yet? Shooting a 6 Creedmoor with sized down 6.5 Creedmoor Lapua brass? Would like info on 105 Hybrid and 110 SMK if anyone has tried it. H4350 powder. Thanks in advance.

Yes, I have a little with H4350. I suggest to start at 40 gr and load up in .5 gr increments until you reach velocity you desire or over pressure. I was getting about 3000 fps at 42 gr/ Br-4 primer. I have been focusing on 115 DTAC's/Rl-16 and have more data with that combo.

Seems like RL 16 is used a lot. More velocity, lower pressure?

I get more velocity for same charge weight...or...more importantly to me..my target velocity with a charge weight that is not compressed when using a 115gr bullet in a 0.145" freebore chambering.
