reloading help
Question:
I started reloading rifle cartridges lately and am still getting some cratering around the primer. A book mentioned this as a sign of high pressure. My loads are not any where near the max. length or the max. grains of powder how can I still be getting this pressure. I would really appreciate any ideas!!! kpj Visit the rec.hunting and rec.hunting.dogs FAQ Home Page at: http://sportsmansweb.com/hunting/ To leave the Hunting listserv list, send a message with SIGNOFF HUNTING
Response:
Primer Cratering and Flattening aren’t reliable indications of pressure in a cartridge. Your cratering could be caused by a firearm that has excessive clearance between the firing pin and breach face causing the primer to flow into that area under pressure. The most reliable method of pressure measurement is case head expansion as detailed by Ken Watters. However one of the number 1 rules of reloading is caution. If you are getting Cratered primers STOP. The deer, elk, goose, varmint, paper target, or whatever you’re shooting at isn’t going to know whether it was hit by a bullet propelled by 36 grains of powder or 50grains. Alan Minga.
