Can I use Federal GM200M pistol primers in place of GM205M primers and get the same results? A friend gave me a brick of these primers and I would like to use them. I do not load any pistol cases.
If I recall it correctly, pistol primers have less robust primer cups so that they will fire readily with the generally less powerful ignition systems on handguns. I would be concerned that they might not be tough enough to use with higher pressure rifle loads.
Just about every re-loading manual printed warns against using pistol primers in place of Rifle Primers. The reason?? Lighter ignition and thinner cups........jackie
