.300 Winchester Magnum

Of all the varmint and big game cartridges developed and introduced by Winchester, the 1963 vintage .300 Winchester Magnum is the fifth most successful. Only the .243, .270, .30-30, and .308 Winchester cartridges are more popular. This is saying more than you might think when we consider that such cartridges as the .22 Hornet, .218 Bee, .220 Swift, .225 Winchester, .307 Winchester, .338 Winchester Magnum, .348 Winchester, .356 Winchester, .358 Winchester, and .375 Winchester cartridges were all born with WW headstamps.

Among the various magnum cartridges available to American hunters, only the 7mm Remington Magnum is more popular than  Winchester's .300 Magnum. Some even go as far to say that for all around use on North American game, the .300 is a more useful cartridge than the 7mm. Whether or not that is true would be most difficult to prove with hard facts but one thing is certain; The .300 Winchester Magnum is an excellent cartridge. When loaded with  bullets weighing 150 to 180 grains, it shoots plenty flat for deer size game at long range, and when loaded with 180 to 200 grain bullets it packs enough punch for cross canyon shots at elk and moose.

Probably the worst that could be said of the .300 Winchester Magnum is that the recoil is a bit much for some shooters and it destroys a good bit of venison when used on deer at close range. But nobody who has seriously worked with the Winchester's big .300 has ever said that it is inaccurate. It is, in fact, a favorite of competitive shooters who try to put them all in the X-ring at 1000 yards.

Most hunters who use the .300 on deer and pronghorn prefer 150 grain bullets, but a 180 grain spitzer shoots almost as flat and destroys less of the eating part. The single best load for elk and moose may just be the 200 grain Nosler Partition or 200 grain Speer bullets.

On the above mentioned text..I do not agree that the 300 Win Mag is a bloodshot beast.That has a lot to do with shot placement.If you bust everything through the front shoulders,yes you are gonna waste some meat.I don`t care if you use a 25-06 and put bullets in the shoulders,you are gonna waste some meat.I hear this same argument from folks who don`t own a 300 Win Mag but still seem to know everything about it`s killing characteristics and its "tremendous recoil".:rolleyes:Does the 300 Win Mag generate recoil?Yes it does , but it is managable even without a muzzle brake.I think personally that its performance ballistically and its downrange energy is more than a fair trade for the recoil it produces..

Here is a picture of the 300 Win Mag alongside a 243 Winchester cartridge on the far left and a Wildcat .25 in the center.It is not hard to see why the big 300 is renowned amongst hunters who push the envelope of yardage in the game fields..:wink:


My own personal loads for my Model 70 Winchester consist solely with the use of IMR4831,Hornady and Winchester brass and Fed 215 Mag primers.

I load the 165 gr Hornady SST and the 165 grain Nosler ballistic tip.I will not give my load data as I am over the book max for one manual and I don`t feel safe handing it out knowing ineveitably someone might try to duplicate it without working it up safely.

My load for the 168 grain Sierra Matchking is 73.3 grains of IMR 4831 with the bullet seated ten thousandths of the lands.This is an extremely accurate load in my sporter.I have on numerous occasions shot soda pop  cans at 300 yards with this load just screwing off.This teaming of a close kiss on the rifling however dooms my Winchester to becoming a single shot but it does perform...


That is enough of my thoughts on this splendid cartridge,lets hear about yours..:thumbs:
