300 PRC Build

[Don A Parsons]

Tag,,, I'm an old school 300 Win & Weatherby Mag dude from way back when. I miss them at times since returning to the old old school Ought-6.

The missing part is the punch down range,,, but I've been lucky so far with the smaller cartridge ,,, "so far that is."

Awesome thread as you get things underway,,, that's what really counts,,, good times in the hunting fields fore sure.

Nah, not really to you.

More for the benefit of all.

Something is definitely going to replace the 300 Win Mag.

Time is a helluva thing, so is progress.

The 300 Win Mag will eventually go the way of the 30-06, the 300 H&H, etc.

I'm determined not to kick and scream about it, because it really won't matter in the end.
In X amount of years, whatever cartridge takes the Win Mag's place will have market support just like the 300 Win Mag has now.

Nobody or nothing is King of time forever.

Hard to know what it will be, but with the way Hornady goes at the marketing game, it may very well be what they are offering in the 300 PRC.

Marketing is what makes cartridges Kings of time. Without it, you have cult.
Some Weatherby, RUM, even my beloved 264 Win Mag.

I do not know, because I don't study those things that close. I have my love. I have my loyalty. I will pass down some very nice 300 Win Mag's and maybe even a rifle chambered in a new cartridge... time will tell.

Im not who you are asking, but I'd go 9 twist unless you plan on shooting pills heavier than 212-215. Heavier than that, I'd look at 8-8.5.

My 10 twist shoots up to the Berger 215's fine, not sure if that's an elevation thing or a temperature thing or both, but I'll take it.
Either way, overstabilizing a little doesn't hurt anything. Understabilizing hurts everything.

So I went to order my barrel today, and I got a bit blindsided... The guy building my barrel can only do 8" or 10" twist, what to do. I think the 10" twist should be plenty for shooting the 212's, but I called Hornady and they hinted that perhaps a heavier load is in the works. Thoughts anyone? Should I go 10" which is probably all I need at the moment? Or should I get the 8", lose a bit of velocity, but be set for pretty much all the heavy pills (even though my sole intent at the moment is the box 212's)?

Thanks for all the help everyone,

Colton

Started a thread recently about twist on a 300wm. From what I got back, I'd say go with the 8 twist. Even if you don't go to the bigger weights you'll still be fine.

Just curious Colton who is the barrel maker ?

Hornady lists a much higher bc for the 212 with a 1:7 twist vs the 1:10
https://www.hornady.com/support/ballistic-coefficient
I'd go 1:8 hands down and never worry about it.
Obviously it's just fine using even a 1:7

 

[wildcat455]

This is all just my opinion and thoughts on it, so take it for what it's worth.
I'd do the 8 twist. Hornady isn't the only one looking to bump up the 30 cal heavies. At some point Berger may come out with a 245.
On the twist rate calculator by BERGER, you'll be at 2.3 with a 215 gr

2.17 with the 230 gr and probably about 2.0 with a 245 if it ever gets made.

I don't think you'll be wanting to use lighter bullets in that rifle though. So if you planned on running 180 grain or less for anything you'll be at 3.55 or so. I'm thinking that's more than a little over stabilized.

No big deal, if you want to shoot those do it out of a different rifle

Christensen Arms offers their 300 PRC with a 1:8 twist. I'm sure they did this with heavier bullets in mind.

Dave Tooley has been playing with the 300 PRC for over ten years. He says in his experience go with 9 as the fastest and a 10 will work. Yes you will lose some bc but apparently the faster twists cause other problems. I am typically a faster twist is better guy but Dave is a sharp guy and has experience.

How was it getting a wildcat var-tac stock shipped down there? They are nice stocks, and light!

I personally think theres something to the really fast twist and jacket integrity. I think that may be why Berger backed off there twist rates. You here people talk of bergers exploding on animals would be interesting to know what twists there running because I've never had a problem but I dont run really fast twist only what I believe will be enough to stabilize.

Talked to mark today at Bartlein Barrels on the 300 PRC. Beside being a big fan of the shape of the bullet and angle of the shoulders he said go 1:10 with bullets from 185gr to 215. And above that go 1:9.
But he said u could and they will put any twist rate in a barrel.
Doing my research now on this gun and magazine length is what I'm mainly trying to research the most. Any way to each his own on how many guns he has or blah blah. U got it to spend than spend it and don't walk in another mans shoes.

Colton - what twist rate did you end up going with?

Does anyone know what bottom metal options are out there for a 300 PRC. I have a Greyboe stock being built for my 300 PRC build and was going to use there bottom metal long action for magazines. Is everyone using the mags with OAL of 3.85.
