[QUOTE="Lefty7mmstw, post: 869799, member: 48043"] Lots of babbling man... Gist is you've built up a really fast 7mm rifle for a client on a m700 action and she'll do nearly 3300 fps with a 175. If it's a small enough case to only use 76 grains of powder to get there you need to be hitting 90,000 psi+. My guess is you are loading well over 100 grains of powder into the case, and if that's the case retumbo is to **** fast of a powder in a 7mm bore. You need to be looking at one of the powder offerings for the 50 bmg for this caliber type; ex. would be h50bmg, rl50, wc872. Good luck with the rl accubond; I'm getting the 150 to 3300 fps in my 24" bbl. 7stw at .5 moa accuracy, but some are having real accuracy trouble with them at high speeds; others are noticing they are pretty soft at high speed impact. Most are noticing the bc's are inflated so out-pound 10% off of the bc before you make the comparison. Keep blowing smoke circles; it's fun to shoot arrows through them. [/QUOTE]
