Just loaded 40 30-06 rds and had 6 misfires, light primer strikes. Tried em again and no go. Primers feel that they are seated properly. Seated em with a Hornady press. I did use large rifle Winchester magnum primers though. This was my first time reloading, my friend who reloads alot said that it is safe to load magnum primers in standard rifle cases as in 30-06, but not a good idea to load standard for a magnum rifle case. No signs of over pressure, groups averaged 1 MOA at 100 yds. All other reloads fired fine and had a deeper primer strike. Do you think that my firing pin is short, or spring is weak? I'm using a post 64 push feed Winchester model 70. I cleaned it and disassembled the bolt, no fouling or debris blocking it's movement. I bought it new a few months ago on gunbroker. It's a new 1980's model that still had the tags on it. Primer strikes are just a tad off center, almost centered though. I've fired 140 rds of factory Remington Corelokts before reloading and never had a misfire. Any ideas, Outside temp was 7 above zero if that means anything.
Thanks Billy Jack
