I am, relatively speaking (re this crowd), a novice and learning a lot from this thread (which is a helluva admission coming from a professed know-it-all). How about simply dropping the reloaded shell into the chamber by hand to see if it binds? Should it fit with light finger pressure?If you meant to say .002” longer than trim length, then that probably isn’t your problem.
Below is the SAAMI spec for a 30-06. The lengths on an AI chamber setup by most smiths will be shorter. Because smiths often setup AI chambers on cases instead of gauges, your chamber dimensions will actually usually be .002”-.004” shorter than the CASE’S neck/shoulder junction. The SAAMI spec on that would be a minimum of 2.1016. If the case your smiths used to set that up was 2.1016, and he barely touched it, and everything else was SAAMI min, then your case mouth would be at 2.495”. However, he likely set it up to crush by .002”+ so your case mouth could easily be at 2.493” or less.
How does a bullet drop into those fired cases necks? They should drop right in. If there is friction on the bullet, the neck is too thick for the chamber, or, if the friction is only at the very edge of the case mouth, then they could be too long and are getting crimped on the bullet when you chamber them.
I'm loading a standard 30-06 with 4350 and finding the casing is pretty full at Hodgon's "medium" recommended powder charge for 165 gr bullet. I checked my powder weight from Lyman electric dispenser against RCBS balance scale and it seems to be spot on. Should I be concerned? Sorry for the hijack. Maybe I should start another thread if there's no fast answer.
Edit: Thanks. Looks like my first question was answered while I was writing it.
