Today I went into my favorite reloading shop and they Winchester large rifle magnum primers limit 200. I bought the primers out habit, but the problem is I don't have magnum anymore more. I sold my 300 win mag awhile ago. I am not sure how to ship primers, but guess shipping is similar to shipping bullets. I guess the best thing is I will post in want to sell. I paid $4 per 100. My question does anyone know how difficult it is to ship?

Use them in your standard large rifle casings......HazMat fees are far more than the cost of the primers.

Ok so no problem using the magnum primers with primary 308 or 30/06. Thanks for the advice.

Use of magnum primers is more related to your choice of powder than to whether the cartridge/chamfering has a "magnum" designation or not. Slower burning or ball powders may benefit from the hotter flame of the magnum cap. They can be used for powders that don't "need" the magnum primer, too - but you should reduce loads to starting load level and work up, watching for pressure signs.

I currently find myself in possession of 5000 large pistol magnum primers, although I don't load any powders in my handgun loads that really need a magnum primer. But as scarce as primers are right now, I think I'll just sit on them, and if need be, I can use them with my usual powders - I'll just have to recalibrate my loads.

Try them out in your 308 and '06; you might be pleasantly surprised.
My best(most accurate and fastest) load for my 6.5 Creedmoor uses Federal LRM primers with Hybrid 100V and Hornady 147 gr ELD-M bullet.
