Home Forums Hunting & Shooting Custom Rifles & Wildcats Anyone here make a 7-300 PRC

Any of you guys play with making a 7-300 prc yet. Just necking down 300 prc brass to 7mm. Basically a longer 7mm prc. Dimensionally everything should work. Mag box, feed rails bolt face etc.

Could you just ream a 7mm prc chamber deeper to the length and shoulder of a 300 PRC. Neck down 300 brass to 7mm. Would increase case volume increasing velocity.
If you have how did it work? Or what is your thoughts? Ken

I would think a 28 nosler would be easier but your project sounds fun. Good luck

How about a 358 PRC? RZ.

That would be a great round too.

That’s pretty much the 35 Newton. I used 375 Ruger cases to make mine. The Newton has a longer neck but generally about the same deal.
