I zeroed it last weekend when the rain actualy stopped and of course there has been dry firing practice laying in the floor at my house lol
I would assume a .300 PRC would be fine with a good .300 wm can... It is kind of just a hot hand loded 300wm and less than a 300 NM
There is a lot of differences between 300WM and 300PRC. Hornady designed the 300PRC to address shortcomings/limitations in other existing 300 cartridges.
30 caliber can works for 300WM and 300PRC. USSOCOM actually uses a 338 can for both their MK22 cartridges 300/338NM....and the 308WIN. Uncle Sugar says, "One size fits all is good enough nfor young Jarheads down range."
Hornady .300 PRC (left) and .300 Win. Mag.
One disadvantage of 300WM is the belted case and head spacing on the rim. PRC shoulder head space is more consistent. Also, throat on WM is 0.315 versus 0.3088 on PRC....resulting in PRC presenting bullet to rifling much more consistently for improved consistency....Consistency is King in long range shooting.One of 300WM biggest disadvantage is a quite short 0.72-inch “head height,” which is the distance between the front of the case mouth and the cartridge’s SAAMI maximum overall length. Ammo factories must load to this standardized maximum, which prevents factory ammo from being loaded with long, super-sleek bullets with the very fine, gradual entry that so benefits extreme-range aerodynamics. In contrast, the .300 PRC is engineered with the latest cutting-edge cartridge design principles, and features a 1.12-inch head height, enabling the use of very long, low-drag projectiles without intruding inside the case. (You’ll find this is a common thread throughout most of the following comparisons.) As an aside, custom rifle makers have been circumventing the head-height issue with the .300 Win. Mag. by chambering it in true magnum-length actions that allow handloaders to seat long bullets at optimum lengths. However, these rifles require handloading to realize full potential. That’s not to say that the .300 Win. Mag. is not a superb hunting cartridge. It is, and the ready availability of a vast spectrum of various loads and rifles makes gives it outstanding versatility. WM takes a Long action; PRC requires a Magnum action........MRAD accepts all due to large mag well and common overall mag size.
.300 Norma Magnum vs. Hornady .300 PRC
Now this one is interesting. In many ways, it does what the .300 PRC does, and does it even better. It’s optimized for use with very long, sleek bullets, and pushes them significantly faster than the PRC does. Yep, it’s spec’d with a plentiful head height, too. 300Norma has more taper which makes feeding and bullet presentation to rifling more inconsistent. Where this cartridge goes wrong is in the size of the case. It’s a necked-down .338 Norma, and although it blasts those bullets out with wicked speed, the cavernous capacity of that gargantuan case is too much of a good thing. It’s not efficient at all, meaning it burns copious quantities of propellant. There have been reports that is some loadings with steep down angle scenarios, the 300NM shifts powder forward leaving void at primer with inconsistent ignition and muzzle velocity/accuracy issues. SOCOM must have resolved this because new MK22 features the 300NM as one of the calibers in kit. NM has lots of recoil and muzzle blast. Worse, barrel life is short. ELR guys like to shoot, so poor barrel life is a significant problem. Also, the .300 Norma requires a really big action. It’s too much cartridge to fit inside most standard-size magnum bolt guns, and even if shoehorned in, you can only squeeze a couple of cartridges into the magazine. All things considered, the .300 PRC is a much more polite, civilized cartridge that is durned near as capable and offers far greater efficiency. And, that, folks, is why Hornady designed the 300PRC.
