I'm glad to see there are other 356 loonies <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
It looks like the 220 Speer is the way to go. Thank you all for the recommendations. I just loaded up 20 of them with 42gr of H322. Next trip to the range I'll shoot for groups and give y'all a report on how they do. The only thing I am concerned about is whether the 220s will expand on our puny TX deer. Any thoughts on that?
xxclaro: You're getting MUCH higher velocities than I am. I am seeing pressure signs with 1/2 grain below max in many of the loads I have tried so far with H322. Nothing severe, as the primers look good and case head expansion is moderate, but I can feel it in the lever when I am getting to max and case extraction gets a bit sticky. There is also a bright ring that forms just at the web/case wall junction on the hot ones. With a wire pick I can't feel any signs of incipient separation, but it still makes me nervous.
I can post my data on my website when I get it all entered into a spreadsheet if anyone would find that useful.
Here are examples of the best loads I have found so far (have not tested group size yet). All are with new or once-fired WW brass, CCI200 primers, H322 powder, and a COAL of 2.555. Rifle is a pre-safety Winchester Mdl 94 "Big Bore" with a 20" barrel cal 356 Winchester. Oehler chronograph 15ft from the muzzle, approx 85 degrees F. All data is the result of five shots.
