Which one for long range , heavy game hunting? Coin Toss?

Same bullet, you won’t shoot that far

PRC usually carries better due to higher grain weights/higher B.C's. realistically, I think your have to shoot past 1200 or so to really tell a lot of difference. there is only like a 1" (ish) difference at 500 yds

They’re close enough that the belt would push me to the PRC.

They’re both .300’s, so how does that work?

Didn’t you just buy a 7mm?

The .300 win was designed in the 60’s to exceed .30-06 capabilities and give .300 H&H performance in a non-magnum length action ( this is why it has the stubby neck).

The .300 PRC was designed to push heavy for caliber bullets at long distance.


Given the almost 60 year age gap between the two, for hunting I like the availability and selection of .300 win mag ammo

Speaking specifically about factory ammo, 212 grain is relatively rare in a 300wm, while it is the standard for PRC. Look at Hornady for example. The highest factory loaded ELDX ammo in each caliber is 200gr for the the WM but 212 for the PRC, and the difference in MV between them is only 40 fps, which is within the standard deviation for Hornady factory ammo. In ELDM the heaviest WM load is 195 @2930 while the PRC is 225 @2810, meaning that at 1K+, the PRC will be the flatter round.

Yes, they are both 30 cal, but that isn't the only factor. Case capacity, max OAL and common barrel twists in a given cartridge are factors as well. if the goal is to go as far as possible, the PRC is the better round in terms of ballistics. but it does cost more, availability isn't as wide, and their are fewer rifles offered in it (though that is changing rapidly)

10/4. Thank you for explaining that.

You building your Nilgai rifle?

This should be a fun project. I would go 30 PRC out of those 2. I think 300 PRC is going to have a good future. It just gives you more room for longer bullets.

For factory ammo this is probably correct, for reloads I am skeptical though, The 300 Win Mag will handle at least the 230gr Berger and per Hodgdon data push it faster than the PRC and from Berger that bullet is stable in a 1:10 twist barrel. BC for the 230gr Bergers are higher than the 212gr Hornady by about .05 on a G7 BC.

Bergara Ridge in 300 PRC.

WM can certainly do 230gr, but I've seen a LOT of people loading PRC up to 250gr (I believe its the Hornady A-tip). That has a G7 of nearly .1 higher than the Bergers, and while Im sure someone somewhere will try to cram that into a 300wm, the PRC is certainly more conducive for it. I just used the hornady examply to try to keep it as appples-to-apples of a comparison as possible. once you talk handloadin, it changes a little obviously, but Id say the statement that "PRC generally runs heavier loads than win mag" is still true.

I would hope that anyone shooting either cartridge to their capable rangeA are not trying to do so with factory ammo.

Aren't these threads really created to throw out something completely not on the list? Like a 28 Nosler or 30 Nosler or 338 Lapua or something along those things?

Neither.... 300 Norma Improved. Just got mine in from Ryan Pierce. It’s stupid accurate just fire forming off the shelf ammo. Only will get better once reloading begins.

A quick look at hodgdon shows this both with berger 230s (the heaviest listed on hodgdon). These are the top loads listed for each, both with 24 inch barrels:

300 PRC 2740 FPS

300 win mag 2835

Great answers, man you guys are good !!!

I like the fact of no belt.

I may sell the 7mm Mag, its so yesterday

Maybe not another custom cuz I wont shoot it a ton. I'm kind of a recoil puzz.

Looking at Bergara and Christensen, Both chamber both .30 cal Mags

The Nilgai outfitter I'm talking to, said If I was confident , I could use my 7mm Mag. I think the guides prefer a BIG gun as to keep from tracking all day. I don't think I need a .416, .338 or .375

Thanks for indulging another one of my threads

I am actually asking myself the same question.
Correct me if I am wrong, but as I understand the .300 PRC will allow longer bullets
Which, if any other manufacturer get on board, could result in a new variety of hunting rounds.

What makes me wonder is, why no Europeans joined the prc train yet. Neither Sako/Tikka nor Mauser or AI have
Offerings. And I am a bit of a Sako/Tikka fan.

But on the other Hand I always wanted a Ruger haha

Edit: the 375H&H isn’t coiling hard. It’s not like you would think it is.
Without having tons of experience with Magnum rounds, I would say .375H&H is more like
A soft, long lasting poke vs these short hard hits.

The 300 PRC is slightly hotter than the 300 WM. It has slightly more case capacity, but about 2 grains. If is also spec'd with the bullet seated much further out, where the 300 WM the bullet is seated deeper. The 300 PRC will be faster by about 50 to 75 fps with the same bullet in either case. Hodgdon's posted load data is VERY conservative and light. And the load data on Hornady's site is also a little light, and does not achieve the advertised velocity with the given powder charges. So there's room to go up there also.

The 300 WM will shoot the same exact bullets as the 300 PRC. The issue you may run into with the 300 WM is magazine length. If you run a rifle with a long mag box, it won't matter. You can seat the heavy bullets out long. I run the 230 Berger and 230 A-Tip in the 300 WM, no problem, if you have the magazine to accommodate it. But you do see the PRC running some 9" twist, and even 8" twist barrels. You can run the 230 and 250 grain A-Tip. Those bullets put the 30 cal on the next level!

That’s clearly a good statement. Thanks.

May I ask what you think about this guy, and his rand on anything prc and creedmoor?

My response to him would be “OK, Boomer”.

The PRC is a redesigned case improving on the older case designs. It gets rid of the belt, it keeps the case body the same size as a 300 WM, if the belt went all the way up. It has a 30 degree shoulder, and is spec'd with a much longer COAL than the standard 300 WM and 300 Wby rounds. Yes, it's similar to the other rounds. But shooters like new rounds and they love having new rifles. New rounds sell new rifles and generate money.

And before I clicked on the video, I knew it would be an older guy cussing at the PRC and comparing it to the old school rounds. I also thought it was funny to hear his phone ring. It was probably a rotary phone!

Yeah, it is hard for me to believe that engineers in the weapon industry work different then we do in HD Equipment.
So yes new products do generate money, but we use science and follow new (safety) standards and regulations to design new equipment. Can’t invent the wheel new, but I can choose if I go in a Ford Model T- or a S550 Mercedes.

The German emperor said once: The car is just a temporary phenomenon, I believe in horses!

I recommend the Win Mag because I have two Rugers that I want to sell. Otherwise I would get a .300 Savage cause I had one in 1963 and the name had a cool factor. You are just going to sell it anyway. Also ready to sell my Winchester model 42

Just go and kill some animals and stop obsessing about rifles and cartridge nuances
