When a round is corroded and neck split, there is no problem, but if I preemp corrosion by pulling a projectile from a crimped round, then the things are much tighter. Any special trick or lubrication to it?
Annealing before re-insertion might be helpful in minimising splitting (it must be an empty case).
I want to try keeping the cartridge under direct sun and projectile is a freezer and then inserting. But no sun today!!
Vlad try a hair drier? but no powder in the case. & not so hot you can’t pick it up with your fingers.
