Headspace excessive or not?
A good buddy of mine just got a Encore and put a 15" barrel for a 7mm08 on it. He was shooting 140gr silvertips. 3 out of 20, failed to fire even with a dimple in the primer. The dimple was not near as deep too my liking but I figured still would fire it off. I also noticed out of the two boxs he had, the primer was alot deeper than my likeing. I figure it for excessive headspace problem. But groups at 100yards wasn't bad at all. If it was headspace I figured that would suffer some.
So I take the three duds from box 1, and 3 rounds from a new box and measure with a head and shoulders gauge. I then measure the fireformed (ones that would fire). I got a 7mil delta. (.007"). Is this excessive? None of my rifles have near that much slop in the chamber. .004" is the most I see.
I figured we could troubleshoot with a encore frame I have to see if that firing pin worked. And take the duds and see if it fires in my 7mm-08 remington.
I know a bunch will say send it back. But I would like to troubleshoot before needlessly wasting money on something that may be an ammo problem and I can fix for myself. I find the WLR Primers to be very hard anyway. I bet Fed 210's would have fired.
I apreciate advise on those who know headspace.
