Whilst becoming an internet expert on rifle rebuilding (sic) I discovered a Midway video where Potter measures the amount of pin that protrudes on firing.
having just rebuilt a rifle and test fired it on a empty cartridge with a fired primer I was concerned about the depth of the strike in the primer.
I have just compared the .270 parker hale bolt to my .243 parker hale bolt and they do have quite different pin protrusions.
Is this likely to be a problem?
.270 - 1.48mm and 1.7mm (manually pushed out)
.243 - 0.9mm and 1.16mm (manually pushed out)
1.7mm seems an awful lot to protrude
