Greetings Guys, I have been shooting the Glock since 1989, and had an original G22 in 1990. I have shot alot of reloads through it, back before I knew any better. My first Desert Classic was in 1992 and I was shooting a load of AA #5 with a 155 Lead Semi Wad cutter. It made major and that was out of stock barrel. Like I said that was before I knew better. In around 1993 I had a KB with the same gun, but shooting a 165 jacketed bullet with Win 231 powder. No major damage to the gun, but I did learn some things. The cambers are very large to allow reliable feeding, the brass had probably been reloaded 6-8 times and blew out at the base of the case. Since then, I have been shooting a G35 since they came out. I put a KKM barrel in mine and when the PF was 175 I loaded a 180 grain bullet with VV 3n37, but since it come down to 165 I have been using VV N320. You need to only use your brass for about 4 reloads, then pitch it. Load the round as long as you can and still have it function, it will usually get stuck in the mags as they are feeding up in the tube. Good luck and stay with it. I have had some good success with my Glocks, and with all the stuff on my G35, it still costs me under 1000 bucks.
