[QUOTE="Brent, post: 29228, member: 99"] Jon, You've hit the nail on the head. H50BMG might be worth a try. H870, like the WC872 is probably too temp sensitive for me to invest time with, so I don't use it. Retumbo and RL25 have worked good with the 200gr Accubond in my Ultra, and the 30/338 Lapua Imp too. I got about 3100 fps with both, but pressure on the case head was higher with Retumbo at that speed for some reason. The Oehler M43 indicated Retumbo's pressure was actually 4000 PSI lower though. Excess pressure signs with Retumbo come on earlier for some unknown reason, it's the only powder I've seen that with. Accuracy has been nothing but great with it so far tho. [/QUOTE]
