The biggest thing with the brass is the crimp. The more crimp the more you work and therefore weaken the brass necks. I get my lead GC bullets from Matts Bullets and I recommend them highly. I originally got some of the 650~ grain hollow point GC lead bullets from Snuffy to try about a year ago. They worked so well I ended up purchasing some 700 grainers from Mats Bullets. Those are what you want to use to impress someone! They are flying ashtrays IMHO.
I use Lil Gun and H110 with good results, depending on whatever I happen to have the most of on hand at the time. I like the 450 GCSWC from Matts with Lil Gun the best for target work as far as accuracy myself.
