...is a winner.
Except the bullet is hanging on by a precious little sliver below the first cannelure, so they tend to pop out unceremoniously under recoil. Not that there's a lot of recoil. Hmm. This could be a problem.
But they're very mild, burn completely, and get the slug down range (sloooooowly). Perfect. Need to run a few more to see if they're accurate, but I'm not worried.
On an unrelated note, blogger's internal auto-correction dictionary doesn't include the word "cannelure."
