The short answer is YES, you can use the Federal Large Rifle Magnum Primer for the 300 Winchester Magnum.

Again, You can check with a reputable and trusted reloading manual, such as Nosler, Hornady, Speer.

Others to verify the use of all reloading components, Either a standard LRM or Match LRM primer should work.

Also, the bullet type, weight, and velocity will impact primer performance. Be Safe, Read, and Research prior to proceeding.

>What about using these primers for 270 and 243 loads?<

The only difference between #215M and #210M primers is the cup hardness. Both primers have the same dimensions.

The #215M is a magnum cup and is designed to withstand the greater pressures of a magnum cartridge compared with the #210M which is a standard match primer.

Both should work well in a 270 or 243 load unless you are using a very light firing pin spring with the magnum primer which is uncommon in bolt action rifles.

However, if you are using a custom AR platform with a floating firing pin you may get slam fires with the softer #210M.

Like the special AR primers for the 223, the AR small rifle (223) primer is a harder cup to help prevent slam fires.

I would use the #215M primer for an AR platform rifle that uses a large rifle primer cartridge. Buy federal primers, federal ammunition catalog, federal fusion, federal ammunition ballistics, federal power shok
