Looking for some advice here chaps.I have assembled about 40 rounds of .308 Winchester, about a dozen of which do not chamber properly.
I assembled these with a Lee Loader (as in the type you hammer the brass into) using once fired brass, and loaded with 150grn Hornady interlocks.
The OAL for each of these is 2.795-7.
I trimmed and chamfered all of my cases before neck sizing, priming, charging and bullet seating each one individually.
I think there can be only two likely reasons for the 12 or so which dont chamber reliably, either:
a) under sized at the neck, or
b) under trimmedAre there any other causes I should be aware of?
I am planning to pull the bullets. Should I attempt to de-prime the cases once I have done so?
I may be able to get away with hammering a primed case into the neck sizing die, possibly using a steel washer to minimize the risk of striking the primer, but I certainly wont be able to use my Lee case trimmer on a primed case.
Should I just attempt to use the de-priming pin and knock the (still live) primers out.
If I do this without causing detonation, can the primer be re-used (at under 4p a pop, should I care weather or not the primer can be re-used ?)
Either way, Im planning to have a dismantling and reassembling session this weekend.
