Gun, Ammo, or me?

Spent an afternoon with friends shooting a variety of guns... pistols and long guns. Had some disappointment with my SR9c, and not sure where to place the blame.

This is the first outing since field stripped and cleaned (nearly 1000 rounds without a single failure till today). I had picked up 200 rounds of WWB 115 gr FMJ at Walmart. Have shot WWB previously without issue. ALL DAY I had at least one, sometimes several rounds fail to fire from each mag. Comparing the primer to other casings, it didn't look like a light strike, but I really don't have experience to tell the difference.

One of my buddies had a box of Federal 115 FMJs (what I usually buy if available), and I emptied a magazine of those without any problems.

Bad ammo? Lousy cleaning job?

I seek the wise counsel of THR!

This problem has been reported by quite a few people, I only remember it because I Google searched it after a guy at the Bryco forums reported problems with his SR9 at just over 600 rounds, exactly the same issues out of nowhere after several problem free outings.

Ruger will almost definately fix the gun for free. Out of curiosity, how old is your SR9? I kinda figured this problem would be worked out by now.

if it worked fine with the other ammo
it's the ammo

if it works fine for somebody else
it's you

if it doesn't work for you
if it doesn't work for somebody else
if it doesn't work with different ammo

it's the gun

Is this a sticky? If not, it should!

Sorry to hear about your SR9c problem. I was planning (still planning, I guess :uhoh: ) to get one.

I wouldn't let this deter you from getting the gun. I'm not convinced at all that the gun is at fault. As I said... 1000 trouble free rounds till now. Only difference... I usually wait a few hundred rounds between cleaning and this was the first time at the range since it's recent cleaning.

I'll shop around and find some different ammo to try later this week. If the problem persists, then I'll disassemble the striker and clean it. I field stripped it and it does seem to have collected some lube.

I was hoping so find some advice on what to look for on the cartridge for light strikes. As I said, I couldn't see much difference in the casings that did fire. Also... I reloaded most of the misfired cartridges and they shot fine second time through the gun.

Did you have your buddy try a mag of the offending ammo in his gun?

going the second time isn't that uncommon, you find it rather more often in russian bi-metal cased and military surplus

it means the primers are hard, or if the dent is the same then it just mean they are not as reliable, and for some reason the pellet wasn't crushed the first time.

that's a ammo problem

Have you removed the striker and cleaned the striker channel? Sometimes if crud builds up in there it slows down the speed of the striker going forward to the point it doesn't have enough "umph" to reliably ignite the primer. If you havent, remove the striker and clean it and the channel really well. Use minimal if any lube when you reassemble it.

Try some different ammo before anything. Winny has a habit of producing some real junk from time to time.. Try some magtech or remmy, pmc.

Wow... must have been the heat, but what a difference that would've made! Dunno where my brain was, but no I didn't think of that.

Been browsing around the 'net and I'm starting to think that's the issue. Did look like there was some cleaner in the striker channel. I'll take it down tonight, then get back to the range later this week.

Thanks, all!

Um, 3 of of 5 bobs on the net will tell you it was the WW box
