I like the new kid on the block. I love my 300 WM. If your looking for ammunition availability, obviously you probably don't reload. Both offer match and hunting ammo. The PRC doesn't offer nearly the number of each that the WM offers. I like change in the industry especially with cartridges. If it makes life easier or performance better, why not. That's not completely the case for this comparison but I'm looking forward to building the 300 PRC project. Getting away from a belted case and going into a match cartridge design intended for long heavy bullets. I'm excited for sure but aware I won't be upgrading in performance much at all.
.300 PRC or .300 Win Mag

The head space thing I do not know how anyone gets that one wrong.
As to the choice pick one. I use the 300wm. Tons of good load data already out there.
I have not had it happen to me but who knows maybe one day I will go crazy and not have ammo and need to buy some. 3OOwm is a standard you can get at most gas stations that sell ammo.

I don't see how you could go wrong with the win mag. Especially if you handload the 215s. ...and if you have been handloading for the win mag already, you've got the gear.
Either would certainly suffice but the win mag is beyond proven and brass, loaded ammo etc is everywhere. 215s from a hot 30-06 do well. 215s from a modest and accurate win mag do more than 95% (or more) of hunters/shooters should attempt.

U can't. I personally love mine. I only want to see how the PRC performs and loads with the heavies. My 300 WM is pretty long with 225s. I plan on shooting the 212s for hunting and 225s for the longer ELR ranges out to 1200-1500 yards max. I think the PRC is designed for the longer bullets and maintaining magazine length cartridges.

As much as I love the WIN the PRC is flat out the winner. faster twist carries the heavy's better and is just a better design IMHO.
That said if you have a great shooting WIN it isn't worth ditching it for a PRC but from scratch im taking the PRC every time between the two.

I have a 9 twist 300 WM that shoots almost everything fine. Just want a case designed for the long heavy bullets without losing case capacity or having a too long of a cartridge for magazines.

You'll need a 338cip mag to feed em
Plenty of people have stories of their ammo never making it to their hunting camp, thus 300winmag is the best since every store that sells ammo has much to choose from.
300 PRC is a more attractive option for sending led down range mainly because it has no belt.
I have two 300winmags. One for hunting and one for target work.
I use CIPs for the 225s.

6.5 creemoor takes up more room on the local ammo shelves than any other. With Hornady behind the 300 PRC I would bet it over takes the win mag soon for ammo selection too. The 300 PRC is a better case design than the win mag.
There are CIP length AICS 300wm magazines. The 300prc uses the same CIP length AICS mag as the 300WM.
I don't see that much 6.5cm ammo on the shelves of local dealers. Big presence on the internet, but I still see more 308s at the local range. It took 6-8 years for the 6.5cm to get traction with the public and by the time it had the PRS shooters had moved on to 6mms.
The 300wm has an installed base that's accumulated over 60 years. If the 300prc is going to take it's place, it'll take a long time to overcome that.

+1 here and +1 to the reply. I run Berger 230gn OTMs and Target hybrids out of a Kimber 8400 Adv Tac 300wm and a custom Rem 700/ AI chassis 300wm. On good days, 1/4 to 1/2 moa and 1/2 to 3/4 on bad days at 1000yds.
Amazing how people think that a longer neck length is somehow superior for accuracy with long bullets.
The moment a case is fired the neck expands, which is no longer holding the bullet, be it .0001” makes no difference.
The bullet, in 99% of cases, is still in the case body/neck when it enters the rifling, especially if it’s long.
How is this any different if the neck is shorter?
The 300WM has the advantage of the shoulder being further forward, allowing more powder space.
Anyway, choose whichever case floats your boat.
I will be running my 264WM (8 twist 29” barrel) side by side with my 6.5SAUM (7 twist 30” barrel) later this year to see which is more accurate. The 264 is a known for me and it holds 1/4MoA for me in F-class, so we’ll see if a new case design is in fact superior or not...I doubt it personally.
Also, belts are not a problem IF you understand how to size your brass correctly.
Cheers.

For me it's not the long neck making it more accurate. That's just laughable. It's the ability to load longer heavier bullets allowing more case capacity for powder. My 300WM using 225/230s unless I single feed, uses up case capacity having the base of the bullet too deep in the neck. CIP mags work if you have a bottom metal setup. I don't like single feed set ups for hunting rigs.

I have the great honor of knowing one of the best smiths with a elite agency that has built more 300wm than many could even imagine, he has even smithed National Championship rifles. He said they shot with the 300 prc, but they know the 300wm so well and it just works so easy, they are sticking with the good ole 300wm.
