7mm rem mg. with bergers

[Silentstalker]

Hey guys, i want to try some berger 168 gr hunting vld bullets. Does anyone have any starting min, max, load info for retumbo, h4832sc, and or rl22? I think i will seat them just inside my magazine length and go from there. What do you think? Any advice or suggestions?

I haven't shot them myself, my buddy shoots them in his 7 rm and his STW. He's using. Rl-22 started at 58- worked up to 64.5 . He said he's using Rem brass and Cci 250 primers. He is also using pretty much identical load with162 gr A-Max. His 7 rm is a browning A bolt.

Start at the lands or .005" off...

I used 64g Rl22 and 70g Retumbo from my old 7 RM/Rem 700 which gave me 2900-2950fps and 1/2 MOA from 24" bbl.
