I picked up a couple hundred of these bullets to play with in my 18" MGM Encore barrel. I had MGM put a long throat in it to maximize case capacity and it shoots 129 Interlocks and 130 Accubonds very well with a max load of IMR 4350.
For the Bergers would you recommend switching powders? If so, to what? I have about a half pound of H4350, 7828SSC, Varget, H380, a little IMR 4831, and need to pick up some Ramshot Hunter. Also RL15 and 8208XBR.
I've read the seating depth recommendations from Berger. Where would start with loads and which powder?
Thanks!

Just remember the burger manual and yes I have 1 as far as I'm concerned the loads were done by lawyers and every Calibre and they have been several that I have loaded for what they list as max would be a good starting point no I'm not telling you to do that I'm just saying that the loads are very mild learn how to go up find pressure come back a tad and that's your winner

Lawyers!!!! I ran QL for the powders you have on hand. It predicted a H4350 max (at or just under pressure max) load to be 1.0 grains higher than Berger's data. IMR 4831 max indicated is 1.3 grains higher than Berger. Start low and work up as always. This is a computer prediction only.
