HHI-7420, no apologies necessary, this whole mess has gotten a little confusing at times for everyone, myself included! I have burned quite a bit of this Trailboss powder, and plan on sticking with this combo, very clean, no locking problems, and I am pretty sure it will average well under 1" at 50 yds. I just shot a 1 3/8ths inch group at 50 yds, just resting off my knees. The acccuracy of this is really amazing for such an apparent mismatch. Thanks for your input, the case capacity suggestion would have been right on if using a modified case.
