Today was my sixth time at the range, sixth time shooting a handgun (G19/4th gen). I've gone through about 800 rounds now, several different brands. Today was a CRAPPY day! I think I shot about as 'well' or no better than day one. Last Thursday I thought I'd made a breakthrough. Likely, I'm grasping at straws here... I used WWB today. Is it at all possible that ammo can have any bearing on aim? I know I'm still a long way from accurate even at 7 yards... but today really discouraged me, even though I'm still pretty much a beginner. Feel like I should be seeing more progress. Not sure what to work on at this point. I'm going back Thursday rather than wait until next week... back on the horse. As a side note, I will never buy WWB again! (100 round bargain box) some primers were rusty, some primers WAY off center, and sticky gunk on several casings. I had to brush off/clean 100 rounds last night... regardless of whether it affected anything today, it was scary that a company is that careless in manufacturing. I was 'warned' about the PMC Bronze I used last week, but aside from a 'unique chemical smell' I've never experienced from ammo, it seemed flawless. No excuses, I likely just had a bad day. Just curious if the WWB could have affected me. I felt kind of 'retarded' today. No pics to post... didn't want to document this occasion & there wasn't much to document, seriously.
