Anyone doing well with these at all?? Got a custom im going to start loading some bigger bullets for.. have ext box mag so should be able to get em close.. any help would be great thanks in advance!!
A friend of mine is getting 3085 fps using retumbo and 230 otm bergers. his screen name is Irdevil sure he would share his data if you sent him a message
215 Berger. COAL 3.843" 215 FED Match primer, REM brass, 91 gr H1000, MV 2985. This is in a factory 26" Sendero barrel. Shows no pressure signs, and shoots real good.
I'm using Nosler brass, 215 Federal primers, with 88 grains of Retumbo behind the Berger 215's and getting 3045 MV and sub 1/2 MOA groups. This is in a semi-custom Sendero with a 28" Douglas barrel. For some reason the 230's would not shoot accurately in my gun but the 215's shoot great. Hope this helps and good luck!
I'm using either 98-102 grains( depending on what you can fit in- 102 is dang compressed) of rl50 or 95 grains of rl33 with the 225 hornady in the 300 rum sitting in rem brass with a 215. I'd try letting her jump a bit first; works fine in my barrel and both the 7 and 30 rum's really seem to want a jump from what I've seen.
