I can do that but i would have to pull all the loads i did for him .  It's just weird that it happens randomly.  I mean the ratio of 200 shot and only couple cracked and the others are fine.  What was the outcome of Hornady brass doing it? 

I've loaded these on my loads and my brothers load about 3k loads and we never had crack brass.  These are my buddies brass he bought.  I've loaded them about 10gr Longshot and about 14gr AA9, and fps is around 1280-1320fps.

I'm pushing my self defense/hunting rounds even hotter 1400+ fps and i dont get any crack brass.  Which leads me to a bad batch of brass.

Yes all these brass where new Starline Brass. I've emailed Starline and awaiting there reply.  I've never seen so many new Starline brass crack like this before. 

Just curious what you guys think of these?  I've loaded multiple 10mm with starline brass and haven't had this issue.  My buddy bought some new starline brass from an online vendor (not starline) and these were the result?  Do you think its a bad batch?  We shot about 200rds this weekend and about 20-25 brass cracked? These were loaded with AA9 and longshot pushing about 1250-1280fps 180gr Xtreme.

Also these where shot from a g20 with a stormlake barrel and 22lb recoil spring

Let me know what you guys think.
