Never dealt with this before so looking for some insight. I recently built an SPR-ish upper to try my hand as long(er) range shooting. Most components are BCM with a Lothar Walther LW50 18" midlength barrel. I purchased a couple different loads in the 70gr range to see which ones it liked best. One of the loads I purchased was the SSA 77gr OTM (from Sportsman's Guide). I shot a five shot group with it and went down to check my target. When I came back I policed up my brass and found that 4 of the 5 rounds I had fired resulted in split cases. I didn't feel or realize anything odd when I fired the rounds. Groups were not out of the ordinary for my abilities (ie shitty as usual) and the brass all ejected in a pattern similar with everything else I've fired through this.
So, what do you guys think? Knowing Sportsman's Guide I checked the box and didn't see anything about them being factory seconds. Do I contact SSA and ask for help? Did I get a bad batch or is something screwed up with my gun? Never had a problem with mil-surp 55gr, the Federal 77gr or the Hornady (forget which load was but the heavier stuff) that I also fired that day. Needless to say I haven't fired any more of the SSA because I'd like to keep all my eyes, teeth, and fingers where they are supposed to be.
Thanks in advance!
