[QUOTE="mrultramag, post: 82590, member: 4467"] with the 200 accubond, I ended up with a load of 95 gr retumbo, fed 215m primer, rem case, oal max to fit magazine on Model 700 rem. 300 ultra. It really liked this load and at 94 gr as well. Getting pretty close to max I think. No apparent pressure signs however. Need to shoot it more and see how soon the primer pockets loosen up. 92 gr of RL 25 is a tackdriver with the 200 accubond as well. I don't know if it is me or my imagination but it seems loads with RL25 have less recoil than with retumbo even with each loaded pretty close to max. Doesn't really matter anyway; its not that bad. Work up from below if you try these. Be careful with RL 25. you may have to adjust your charge for your lot of powder. I would say that 3150-3200 fps with a factory 26 in bbl rem 700 would be right at max with the 200 accubond and either retumbo or RL 25. I would give retumbo a ohsoslight edge in velocity. Each gun is different though. [/QUOTE]
