Anyone else building a Savage into the 300PRC?

Actually signed up for this forum for a different reason but seen this thread so I'll offer some information.....

In regards to out performs the .300nm.....it does out perform the .300wm at normal working pressures. The .300prc will be an easy 75fps faster then a WM. Where it out performs the Norma in my opinion is the Norma has too much case capacity and there isn't in my opinion a suitable powder to use that case capacity with out going over pressure. The PRC falls in between the two. A Norma with a 220-230gr. bullet with the powders that are out there is at max. pressure in the low to mid 2800fps. range. Yes you do see some guys claiming 3000fps. with a 220gr. bullet etc....but I will guarantee at that velocity they are pushing pretty close to 80k psi.

The .300wm with a 220gr. bullet at max working normal pressure your only in the 2700ish range velocity wise.

How do I know...we make plenty of ammunition test barrels. So I have data on the pressures of the rounds vs. velocity.

As you pointed out the Norma is also a bigger rim diameter. So you need a bigger/altered bolt face where as the PRC uses a standard mag. bolt face.

I built late last year a new F open class rifle on a Barnard action and the barrel on it is in .300 PRC. I'm running 225-230gr. bullets at 2900fps and the gun will hold 1/4moa for vertical at a 1k. I can use a different powder and get more velocity with out going over pressure if I want to but no need to push on it. My barrel is a 1-9 twist. Standard PRC chamber. It's a nice chamber design. They did there homework on it.

Im having a barrel made with a 1:8" twist (5r). Am I shooting myself in the foot with that fast of a twist?

Your doing a .30cal in a 1-8 twist? What are you chambering it in? Am I correct to assume .300PRC or something different?

Yes a 300prc, 28" barrel heavy palma, 1:8" twist. Should I call them and have it changed over to 1:9" if they haven't started it?

The 1-8 won’t hurt ya. I don’t see a need for a 1-8. So to me a horse a piece. If your just going to be shooting heavy bullets like the 225 and heavier then leave it as a 8 or we can change it to a 9 twist. I know we made plenty of 1-8 twist barrels for Hornady as well if memory serves me correctly.

Saami spec. On .300PRC is 1-10 twist but again if your shooting 225 and up to 240gr. Bullets I’d run a faster twist then a 10 myself. The 230SMK if I recall need like a 1-9.29 twist min. At 2800fps. I’d have to rerun the numbers to double check that as it’s been a while since I did the twist calc on them.

The barrel can be started....as long as it’s not rifled we can change the twist rate for ya. No big deal. Rifling is the last thing that gets done anyways.

I rechecked the twist calc and at 2800fps. you need a 1-9.24 twist min. for the 230gr. SMK

Also depending on powder....I know of some guys running the .300PRC out of long range PRS type guns and running the 225 bullets around low to mid 2900’s out of a 27” barrel.

That’s getting it done!
