Went shooting today to kill some time with the 338 Lapua.

Love the gun and got and impressed myself holding within a few inches at 800 yards. I had several misfires though.

Using Winchester Magnum primers and 87.4 gr MagPro powder. Not sure if it's a reloading issue or a firing pin issue.

The case on the left was a fired
The middle one misfired
The one of the right fired on the second try

Any ideas???







First time out to 800 yards :D :D :D

Thanks for the ideas all.
It's only had about 50 rounds through it so it should be covered by warranty. I put about 15 though it the first time and had zero misfires. I did about another 10 or so so check loads and got three shots nearly touching at 300 yards so I stopped. Still no misfires.
I absolutely hate the accutrigger set up so while my wife and kids were at her sisters just before new years I stretched out on the living room floor and "practiced" trigger pull on the living-room floor but I had two of these to run through it. http://www.midwayusa.com/product/178317/harbour-arms-snap-cap-338-lapua-magnum-aluminum-package-of-2 so it's not been "dry fired" per-say. Now it has the misfire issues.
Any chance that helps narrow down the possibilities?

100% reloads. I was using some primers at first that were not magnums and had some issues with the timing of the boom. But they did all go boom. Changed and had no issues until after I did the firing with the spring loaded rounds. Not sure what the result is from dry firing. Maybe something with the spring loaded rounds. I dunno.

My guess is bad primers. I just fired off 10 cases with primers only and not a single issue.
