I was wondering what the lengths of the No 4 bolt heads are, sorted out by 0, 1, 2, 3. Plus or minus on the lengths, would be helpful.
Reason I ask, is because I'm reloading for the cartridge, and have three rifles with variously sized chambers and am looking for case life. I realize that the correct thing to do, is to segregate brass by rifle, and keep it segregated. But, while trying to sort out how much to resize in order to have easy chambering in the shortest chamber, I may have found an excessively long chamber in one of the rifles.
The suspect, is a 11/53 Fazerkerly which showed little use when I bought it fifteen years ago. Has a #2 bolt head on it. I can put a target paster on the head of South African ball ('70s) and close the bolt with no final resistance. I can chamber spent cases shot from my tightest chambered rifle into this one, and close the bolt with no final resistance.
Where I live, the couple of gunsmiths do not have .303 headspace gauges.
I was wondering if trying a 3 bolthead on the long chambered rifle might be helpful. Easy bolt closing on a target paster/over ball, might say that the headspace on this rifle might be long. Doing this, might help rein in the herd on brass elongation. Thoughts?
This is my first post here. For some years, CSP seemed to be unfindable by me after it went away. But CSP was where I learned of 9/11 one morning.
Thanks for any help. Anybody that wants to talk or give advice on .303 reloading, I'm all ears.
