Starline is awesome brass, and sometimes EVEN cheaper when you can find the deal.
I just scored a batch of 700 pcs of brand new Starline..... traded for a large batch of .45 ACP brass, and some pure lead. (I made out better than the other guy on the deal! I had tons of 45 ACP and almost tons of pure lead. Actually, some other guy in Montana needed some of my excess 44 mag brass, and sent me a box of pure lead in payment. I'm back to where I was with lead. Net = traded 44 mag and 45 ACP brass for .500 brass.)
Another way around the cannelure/crimp/powder load issue is to do what some of us do (Thanks E/C for the tip!)....
load one round at a time.
That way, you have no set back issues as you fire the gun. I do that on most of my hot loads now as a matter of practice.
Note: I found a pair of gel cushioned gloves that I love, at Graingers!
They are called, "ERGODYNE PRO FLEX" 900 Gray Tag also says 0309HL2

That link takes you to the XLarge size, which is what I needed. The sizes run weird, so you'll have to try a few pairs on to make sure they are right for you.
What I like about these is that they are leather with some spandex, and the gel is well placed. Even with the gun clinched in my hand, the gloves are not binding, and feel great. Impact is amazingly reduced.
I sought these out after trying E/C's gloves (made by Uncle Mike's.... which no longer offers padded shooting gloves)..... Just thought I would pass along my experience with trying the various gloves at Graingers.
