Re: Primers?
Primers might be the least critical component, but you can't switch indiscriminately. The intensity of the charge could make a slow powder a little faster, or visa versa. Personally, I buy Federal primers almost exclusively except for two rifles chambered the same and I keep the loaded ammo separated by using hollow points and Federal 210M in one and VMax and Remington primers in the other. That way, it's a visual I.D. no matter which end I'm looking at. (Remington primers are the only one's that are brass color)
I have never seen Wolf primers? If it is anything like Wolf ammo, I'm skeptical. BB
edit: PS, I like your attitude. You will never SAVE money handloading, even if your time is worth nothing.
