.300 win mag or 6.5PRC

Thinking about adding a another calibre to FAC for Fallow and Red. I am not a reloader so would have to be factory.

300 win mag or 6.5PRC?

Pros and cons?
 
I like .300 win mag. Better ammo availability and more rifle choices if you’re not home loading, plus it decks everything you point it at and doesn’t blow the smaller deer to pieces.

Below is the exit wound on a muntjac with 300 win mag.

I can only speak for the Win Mag great bit of kit, I shoot Federal Trophy Bonded tips 165g shot everything from Eland and Zebra to Springbok in SA and Namibia and Boar in Turkey and Croatia. Fast flat and lots of punch, some forces not keen on their use in the U.K.
 
Mix them together and get a 300 PRC….

If you want to avoid the recoil go 7mm PRC.
300PRC and 300 Win Mag are both great cartridges. But in my opinion, both are way more than necessary for the intended use. I’m not familiar with the hunting conditions and game that present themselves in the UK, but for deer of any sort these would both be too much. Unless you’re hunting at extreme distances. You’re going to be dealing with pretty stout recoil with the 300PRC and a lot of meat damage at the other end. 6.5 PRC or as someone else said above 6.5 CM would be more appropriate for the intended use.

There’s no such thing as too dead…….

We are staring a ban on lead in the face, people are stepping up cartridge sizes to sling copper fast enough for reliable expansion and the only way to to maintain bullet weight is to step up a cartridge or 2.

In a 308w a 165gr copper bullet may have performance issues after 250 meter, in a 300wm maybee 400 m.

Sure. But in my experience you can usually go down a size or two when shooting copper bullets and get better results. It lets you get higher velocities to ensure good expansion and terminal performance. And I don’t recall the 308Win being part of this scenario. The original question was 300Win Mag or 6.5PRC. Both of these and the 300PRC are great. But my argument is that either the 300PRC or Win Mag are way more than needed for deer even factoring in the use of copper bullets. Both of those 300’s are used here in the USA with Copper out west at long range on Elk and Moose and bear. Deer just don’t need that much horsepower. If you are willing to put up with increased recoil, ammunition costs, and meat damage, then yes, dead is dead. All I’m saying is that for the intended use, the 6.5PRC, or the 6.5CM would give you more than adequate performance on any deer species and afford lower recoil, lower ammunition costs, and less meat damage. I was just attempting to answer the original question. As far as there being nothing as too dead, that could lead one down the slippery slope and end up with a 460 Weatherby for squirrels 😑. I’m just saying that the 300PRC is an awful lot of gun. Especially if I was only going to hunt deer. But to each his own.

OP has not asked about 300PRC. I dont have any need for 300mag on deer for mee a 6,5 or 308w are plenty In scandinavia 180gr-200gr are the normal bullet weight in 30 cal so 165gr are a lighter choice roedeer season and bear season both starts in august. I assume OP alredy has rifles for smaller deer cartridges and want something extra.

Correct. The OP asked about 6.5PRC and 300Win Mag. Someone else in the comments brought the 300PRC into the discussion. Not much separates the two 300’s other than factory twist rates and the PRC as such can use longer bullets out of the box than the Win Mag. If he wants more then either of the 300’s will scratch that itch.
 
The OP did also say he doesn't reload so surely it has to be 300WM of the two? 7mm RM would probably also be readily available at a lot of gun shops but 6.5PRC probably wouldn't, although the OP probably knows if he can easily buy ammo for either from his local gun shop

Out of curiosity, is mail order ammunition purchase permitted in the UK? If not then that definitely makes local availability much more important.

I’ve got a 25-45 Sharps for deer, it kills deer with 28 grains of powder, I have a 300 PRC that burns 80 grains of powder and a few in between, they all kill deer or squirrels 🙂.

To be fair the biggest calibre I’ve killed a squirrel with is .280 rem 🤔.

This is a munti doe, about 20 lbs dressed, 300 gr from a 45-70 at 100 yards was probably overkill, but you probably get my drift 😂.
