I hope I'm not repeating a discussion topic here. I'm faced with a delima. After my yearn for shooting the big calibers like the .375 H & H and .458 Win Mag, I've downsized over the years and have a stash of Federal 215 Magnum Rifle primers left to the tune of about 4,000. With the primer shortage, I'd like to use them up.
Now, I've used mag primers in jacketed loads and know that you can get in trouble switching from regular to mag with loads near the top end in jacketed. Been there and done that in the .270 one time.
My question is. How about using them with cast in the .30/30 and .30/06 instead of regular Large Rifle primers. All loads down in the 17-1900 FPS range and nowhere near top end. Powders in use will be MS4759, MS4198 and Tu2000 left over from the milsurp days of plenty.
I've used them for years in the .45/70 as it gives better ignition with that big case which can be erratic with some powders.
Anybody here have any experience with this, especially Larry with his meticulous tests on the small pistol/small rifle switch in the 9mm. That helped a lot.
I'd offer to trade with other members here on the site but for the hassle of shipping hazmat.
Anybody have any experience doing this, please weigh in here. I'm sure this question has come up before./beagle
