I was working on load development yesterday and had an annoying issue with two of the test rounds.
I chambered two consecutive rounds, and attempted to extract them without firing. It took an enormous amount of effort by two people to get them out. The bolt was locked in battery and did not want to budge.
I inspected the cartridges, and they seemed dimensionally similar to the rest, so I can't see any obvious problems.
Two observations: these are both nickel plated RP cases, and they were resized in a Hornady full length die while the rest of my reloads were Lapua brass and they were sized in a RCBS X die.
The bullet is the Sierra Match King, 69-gr, COAL 2.258-2.265, with COAL variation probably due to the surprisingly irregular bullet tips. Seated with a Redding Competition die. No crimp. Rifle used is a JP CTR-02 with a Wylde chamber.
I did not fire these rounds, of course. Just to make sure, I rechambered one of the sticky rounds and of course, I got the same results. So whatever the irregularity is, it did not get "ironed out" by the rifle's chamber.
I realize these two "sticky" cartridges must be dimensionally different from the rest, but I can't find anything wrong with them! Any ideas?
