Been looking around net about Getting info modifying my 300win mag project rifle into 300prc or any of other caliber with a tad more punch or able squeeze in longer projectiles, any advice or preference to shoot a mile plus with a preferred round ?

300 rum for me. The 300 prc has my interest and looks sexy but till Norma or lapua makes some brass I ll be hesitant to head that way.
Dont discount the 30 nosler either, wicked cartridge
The Norma cartridge is based off the 338lapua case which means you can probably cross that one off your list. Bolt face would need to be opened up and the ammo wont fit in most 300win mag class magazines as its too fat. You really need a 338lapua class rifle to make a 300norma properly
Dont dick around just buy Andys 338 lapua thata for sale

fuck all those pea shooters what you want is a 416 Barrett
Ah,never seen one of them before.
I think you are correct.
That's what he needs
Yes hopefully that works out, may just keep the win mag chamber standard if I get thatQuote:

The same would be for the 300 PRC and the 300 Norma.
30nosler if you reload 300prc or 300win mag if factory ammos the go
30 blaser could be another option. Norma brass
If thats the case then I think it would be wise to factor in barrel life and the amount of powder used.Quote:

Apparently the barrel had a fair bit of throat erosion and fire cracking after 250 rounds.
You need quite a few rounds for some of those comps also.
308 norma magnum or 30-338 maybe?
Custom 300 Win mag chamber will do everything a 300 PRC does. 230 and 250 gr. Check out Mark and Sam on youtube. They running same powder charges and getting less pressure from Win mag than the PRC.
I saw that one. the 300 win mag is pretty impressive. some of these new calibers carry some hype. Be interesting to see with lapua brass weather the 300prc would test any different.Quote:

Good advice. That would remove the need for new brass and dies.Quote:
