7Saum velocities...need help.

I am shooting 180 Berger hybrids at 2800 with 63.2gr of H1000…22” barrel with TBAC can.

This is encouraging, maybe I don't have a $2 hooker for a barrel. What powder are your using?

Mine shot best with H4831sc, for several different bullets 162/180g. But it shot well with H1000 too with 180/195g.

RL 23 and 7828 are my favorites in 7 Saum . Case not big enough for good velocity from H1000.

Rather hit ‘em slow than miss ‘em fast

Not a slow barrel. My apologies for the barrel drama. 64.5gn h1000 yielded 2910 with an ES of 9 fps. Sample size of 4, but I think its promising. 65gn yielded 2925, ES of 13fps (4). No signs of pressure or even slight primer flow. Round count of 49 on barrel.
