  • Miss October, The legendary 300 Winchester Magnum






    [align=center].300 Winchester Magnum



    [align=left]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.

    [align=left]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 sameargument 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".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 energyis more than a fair trade for the recoil it produces..[/align]

    [align=left]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 theenvelope of yardage in the game fields..:wink:[/align]

    [align=left][/align]
    [align=left]My own personal loads formy Model 70 Winchester consist solely with the use of IMR4831,Hornady and Winchester brass and Fed 215 Mag primers.[/align]
    [align=left]I load the 165 gr Hornady SST and the 165 grainNosler 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.[/align]
    [align=left]My load for the168 grain Sierra Matchking is 73.3grains of IMR 4831with the bullet seated ten thousandths of the lands.This is an extremely accurate load in my sporter.I haveon numerous occasions shotsoda pop cans at 300 yards with this loadjust screwing off.Thisteaming of a close kiss on the rifling however dooms my Winchester to becoming a single shot but it does perform...[/align]
    [align=left][/align]
    [align=left]That is enough of my thoughts on this splendid cartridge,lets hear about yours..:thumbs:

      Well I see that and its a sweet win at that:lol::lol::lol:



      here is my Fav. Load and remember to always start at 10% less and work up slowly.



      it is a 165 XBT over a 78.0grs. of H4831SC in a W&W case with a WLR Primer out of my old 300 Win.Mag i was getting 3188fps and if I did my part right it would produce 0.4"groups

      As for a great round there is nothing in North America I wouldn't be afrid to take,Bullet choice for this round is one of the best you can load a 100grs Varmint bullet up to a 250 Soild for African game.

      Lets hear what ya;ll think of the 300 Win.Mag

        Never owned a 300 Mag. I know a few guys at my range who love 'em. Seems to be their favorite long range deer and elk rifle. It's definitely a cartridge that can get the job done.

        Guess I'd better make room for another rifle coming home one of these days.

            I have always liked the 300 Win mag but when i purchased my first 338 i sold mind to my hunting buddy and he has sincetaken three elk and a number of whitetail deer with it ,using the Seirra 200 gr BT and IMR 4350. The rifle is a SS Browning Stalker and groups this load under a inch all day long. I have been thinking of building me another and if i do it will be the 300 H&H , just because i have never owned one.:thumbs:

              I owuld have thought we would have had more posts on this wonderful cartridge.I am of the opinion that although not many fellas in my neck of the woods use it,it would be popular in the northwoods where elk roam...:confused:

                :confused2:

                Its OK I guess.....if you MUST have a magnum!

                but as you well know I am just not a magnum fan...except for the .375 H&H.

                  Here's mine, a Remington 700 BDL I bought new back in 1972. It still looks and shoots like the day I bought it. The .300 Winchester is one caliber I would never be without.It's one of the few that Remington put out with a "blued" Stainless Steel barrel. billt.

                    I personally love to shoot the .300 Win mag. I don't own one but a few buddies do. Unfortanatly they get used at the range more than in the woods. They do have some recoil and it's managable but I can seewhere a newbie high power rifle shooter might develope a flinch. If one were to fall in my lap with perfect price I would buy one in a minute.

                      Kind of interesting how things evolve. I really wanted a 264Win. Mag. at one time. All I considered was muzzle velocity, not bullet weights or barrel life, nothing but speed.

                      Then I suddenly became aware of the merits of the 7mmRem. Mag. Better bullets, better barrel life and better ballistics. That's what I wanted.

                      Eventually, I actually had a need for a more powerful big game cartridge, and started watching the ads. Then a buddy called and said there was a Model 700 for sale out by him, but it was in 300Win. Mag. Had a decent 3X9 Leupold on it, too.

                      Well, I had my heart set on that 7Mag but what the heck, the price was sure right, and I could have it rebarreled if it didn't shoot. Right?

                      I hit the books and found out right away that the numbers compared with everything I desired about both the 264 and the 7Mag. Hmmm? Guess you just have to look in the right place?

                      One thing I found out was that a 300 Weatherby beat the Winchester version by quite a bit, as far as muzzle velocity, especially 150 and 180 grain bullets. However, it seemed like a 165 grain bullet was closer in performance, maybe it was a natural weight for the powder capacity of the Winchester case?

                      So, after dolling it up with a fibreglass stock, I went to the range with four loads of two different powders and shooting the 165 grain Hornady flat base. The first two loads were about 74 grains of IMR4350, and one was okay but the slightly hotter load was opened up a little bit.

                      Theother two loadswas with a max load of 80 grains of H4831, and 79.5 grains, both of which printed about three quarters of an inch for five shots.

                      That's it, over twenty-five years ago, and (truthfully) it still puts that load under a quarter. Never developed or needed any other load in that gun.

                      I notice several comments above about 165 grain bullets. I thought it was my little secret? Elk and deer load, and several coyotes and a bobcat or two, seems to do it all?

                      I have put a few 168 grain Noslers through it, just for the heck of it, same load, always with the standard w8½ primer. It is actually a tiny bit better. All my loads used to be right out of the book, but the books (these days) have become a lot more cautious. Probably with advice from the lawyers. All I know is it's safe in my gun, gives me 3265fps. It's not uncomfortable to shoot from the bench, I think the word "Mag" scares some people?

                      So, I found it by accident, but it has found a warm place in my heart, and I was not very receptive. I just couldn't help it, the performance won me over. In my book, it's higher than #5....and I don't need a RemUltiMag, thank you.

                      Good hunting. LB

                        One of my favorites!!

                        I have been shooting a 300 Win Mag for a little over 20 years now. Used it mostly for whitetails, but took it elk hunting as well. I know alot of folks say its overkill for whitetails, and maybe it is, but with 150 gr Core Lokt, it is one awesome deer cartridge. Doesnt do alot of damage to the meat, as long as you stay away from the shoulder or backbone. Normally just knocks a hole through them, coming out about the size of a silver dollar or so.

                        Thing I like most about it as a deer cartridge is it really cuts down on tracking. Most deer shot are DRT.

                        Actually, its been on the shelf the last two seasons. Since I built my 25-06AI, I have been using it. I gotta say, although the 25 is a great deer gun as well, it doesnt do quite as well as the ole 300. I got a buddy coming down to hunt with me this year and hes using my 25, so Im breaking her out again.

                        Cant wait.
