my recient groups with 120gr by volume were good, i suspect that they my get tighter with 110gr. what concerns me is the loss of velocity. i had been shooting win209 primers. do you think by switching to the hotter cci209m that i would gain a bit of the lost velocity by reducing the powder charge?
i read that round balls were shot out of a .32 rifletest what effectsprimershave on on the overall velocity whenkeepingthe powder charge the same. the cci209m had quite a bit more effect.

Dropping 10 grains of BH209 would really not be a big concern. 110 grains is plenty for ANYTHING you want to hunt.

x1 The largest amount I've ever hunted with was 110 and that was only because the gun liked that amount. I wouldn't worry too much about the velocity dropof 10g.
