Misfires & Primer Depth
Two misfires recently using Remington Ammo.
Upon examination with Depth Gage,The primers with the misfires are 15 thousanths depth.
Is that acceptable?

Sounds deep to me, but not unknown.
Years ago, I had some RP .25-06 brass with deep primer pockets. A primer seated to the bottom would get a light strike and some misfires. A primer seated just flush would fire but accuracy was mediocre. I traded the rig rather than fool with it.0 -
FWIW, if the problem is deep primer pockets I'd try some different brass before I'd ditch the rifle.[:D] 0 -
i'm assuming you mean factory ammo. it is my understanding that when the brass is formed that the primer pocket and flash hole are pressed into the brass not drilled (machined) hence came the invention of the primer pocket uniformer tool and the flash hole deburring tool. i would venture to guess that the machine that punches the primer pocket/flash hole needs to be calibrated on occasion making it possible to produce some brass out of tollerance.
the only other guess i can offer is that someone has recalibrated his primer pocket uniforming tool and made the recess slightly deep.someone correct me if i'm wrong but there is only two choices in large primer uniforming tools. large pistol and large riffle and the difference between the depth of the two is .002 of an inch. all small primer pockets use the same uniforming tool.
if you ever find the answer to the over depth please let me/us know.0
