Ok, is 300PRC "essentially" 300WM, loaded long for heavies?
Been into the rabbit hole on these and seems once you load WM long with heavies, theyre basically the same?
So if your WM uses CIP mags (or longer like the Seekins), is there really much of any difference between the two if you're a reloader?
The juice is not worth the squeeze. Most comparisons I've seen are always a 300WM 180gr, maybe a 190gr at 2850fps against a 300PRC 212gr at 2900 FPS and the slight edge makes all the bandwagon guys say "yay, it smokes the WM". Ok. Best comparison is to shoot like projectiles at whatever load possible. Which nobody does ever because it kills the narrative. Shooting a 220gr SMK at 2850fps from a 300WM is much different. Or even a 215 Berger at 2900FPS.
More rambling, the main differences once you get into the above are:
-belted vs beltless
IDK if this actually matters. The arguments for either are kinda weak IMO.
-PRC has tighter chamber specs
Not always a good thing. If you're a belly shooter or a bench only guy, then great. If you actually do move around a dirty environment, then take into consideration.
-WM is generally twisted slower, so can't go as heavy as PRC...but can certainly get "close".
They're both commonly 1:10, but many do the PRC at 1:9. 1:10 should not preclude shooting heavies from a 300WM. I think there's some kind of stigma that you must only shoot 180gr or 190gr from a 300WM. You can get a 1:9 barrel for a 300WM. It would probably be great.
My thoughts on all the PRC cartridges are the same with one slight exception which is the 6.5PRC. These cartridges don't really do anything so significantly better that I would have to invest in a whole new setup to shoot. They're pretty meh. You can only reinvent the wheel so much. The 6.5PRC does have enough ass to make me want to consider it, but so do a few of the 6.5 magnum cartridges out there.
If I was going to move on from a 300WM, it would have to be something worth the cost in time and money and the only two cartridges that would do that for me are 300 NM and 300 RUM, which is something I'll still probably do.
Now if you have money to blow and have to have the latest thing because it's FDE and the internet says so, because it's your hobby, then great. But the leap in capability really isn't there for me to chase it as far as the PRC series of cartridges goes.
