Well thank you all for the input i will try all your input.by the way this is my first rifle build so im still learning alot if any of you have any other input about anything i sure would like to here it!!!
My 7 mag loves RL-22 with any bullet I put in it. Haven't really messed with to many other powders besides Retumbo. Retumbo definately showed a velocity increase, but not as good accuracy wise. I didn't mess with it to much though as RL22 shot 1/2 MOA with at least 6-7 bullets.
My 7 RM is just a rem 700 BDL custom deluxe w/holland brake and trigger work w/leupold 6-18 w/turrets. Nothing special, but it shoots ridiculously well for a factory sporter...
you don't need 168 berger unless you shooting 600 yards or 1000 . i have had great success out to 600 with 139 horn and h-4831, like i said my big groups are 1" . i have shot 140 accu bond and 140 partitons too around 69.5 grain of h-4831. cci 250 wlrm or 9 and 1/2m primers.
