Craziness, but I survived Wednesday night's tests....
I ended up loading some 231 with the bullet seated well back into the case. The usual (maybe 0.010") shoulder out of the case over 4.7gr of 231. Couple of misfeeds, but nothing exciting. IMHO, that'd be easy enough to work out, without any problems if I seat the bullet out just a smidge more. OAL is very short....
I was going to try 4.2gr of WST (with the same bullet seating), but got lazy and just refilled the powder measure with WST to see what it'd throw before mucking with it. 4.4gr.... I'd planned on testing 4.2gr, 4.4gr, and 4.6gr, figuring that the extra pressure the powder is supposed to generate would put that top limit in.
With the press already set at 4.4gr, I loaded up a large handful. Probably not the best idea, but it was getting late....
Again, same OAL-related feed issues a couple of time, but it worked fine, and the pressures seemed to be well in the range I expected for "safe" - no split cases
, primers look normal, etc. Soft "push" type recoil, too. Feels more or less like 231 at 4.7gr. Becka shot off a bunch of it after I was satisfied that it wasn't going to explode or worse. The 4.7gr of 231, OTOH, seemed to be a bit snappier with that Hornady bullet than it usually is with the one I usually use. Slight indication of too much pressure - slightly flattened primers - but not enough to panic over. I shot off those. Used the Rock Island, which is slightly more solid
. (After the initial testing, we shot the WST loads in my Para PX745EM, which is a GM clone, and not quite as solid.)
Overall, looks like a winner, but I still want to try seating the ball just a smidge further out for next week's tests.
Thanks for all the info, guys. Look like I can keep on shooting for a little while
.... Some nights we shoot more bull than bullets anyway, but Becka likes to make noise
, so we ran through everything I brought with us.
(I still think the powdered lubricant is Moly
