Well I've been sitting around trying to do up my first 7mm handloads today, and I've been having a puzzling problem. My handloads are very difficult to chamber. At first I thought maybe the cases were too long since I hadn't trimmed them and a couple were a thousandth or two over the original case length. But even cases that are not too long seem to be difficult to chamber.
Here's what I've tested:
-Empty brass (not run through resizer die) much longer than my the cases containing the reloads - fit no problem
-Factory ammunition - no problem
-emty brass shorter than my reloads (not run through resizer die) - no problem
-empty brass within spec through resizer die, tight to chamber
-empty brass over spec through resizer die, tight to chamber
-loaded reloads, tight to chamber.
EDIT:
I just measured every part of the cartridges, and I noticed the factory ammo has a .015" taper from the base to the shoulder, while my reloads DO NOT, it's more like only .011". This is what I suspect is causing the tightness, but WHAT could be causing this problem?
