300. Win Short Mag

Experience with this caliber please!.

Anyone here shoot a 300. wsm? What grain do you use? Do you like it? do you suggest it? What do you hunt with it?

At least once a year i do a big game hunt. Usually its Moose, Black bear or Caribou and there is a possibly of elk hunting. Right now i shoot a 7mm rem mag and i had a couple people tell me that with black bear the smaller bullet isn't recommend. I know my 7mm will put them on there *** its just i want that little extra range, power and bullet size. I would make my 7mm my deer rifle because it shoots 140-150 grain bullets better then it shoots the larger 160-175 grain bullets. I found a fantastic deal on a 300. wsm in a browning a-bolt and i know i will regret it if i dont take it. Im just asking if people like theres and how it works for them

Re: 300. Win Short Mag

I have one in the safe that I have no stock for so itís unfired. But I have been shooting my 300 win mag quite a bit lately and it is essentially the same thing. I donít think you will be disappointed at all especially for the animals you have listed.

If you only want to do one load for all the animals you mentioned pick a good bullet like a 180g Barnes TSX or MRX. They do cost a bit more but if I wanted to use them in a factory rifle magazine this is the bullet I would chose.

There are many other good bullet choices like Accubonds, SST, VLD Saraccos,Partitions but I cant speek for there use on bears.

With the number of bullets available in 30 caliber a 300wsm is very good for anything you have named and also a lot that you have not,,,,go get it..

Re: 300. Win Short Mag

exept I can say YES, Accubonds work well on bear out of a .300 win anyway.
+1 also with Flyin Lizard ......BUY IT! If you dont like it sell it. There are tons of .300wsm fans everywhere. You wont loose your $

I love my .300wby, but I still want a .300wsm when I can afford one someday

I've used the 168 gr TSX on elk out to 300yds. I will soon be playing with 168gr Tipped TSXs. I'd second the recommendation for 180 gr TSX for moose.

Re: 300. Win Short Mag

I think the 300 WSM is a great cartridge, very close t the 300 WM in performance. Either one will kill anyhthimg that walks in NA. With RL17, you should be able to drive a 177 GS about 3300 fps, if you have a 9 twist. Assuming that bullet's BC is .6 plus and it expansion velocity is 1600 fps, it is a 1200 yd plus killer.

With a 10 or 11 twist, I would go with the 180 E-tips. No offense the TSX guys, but the E-Tips have a higher listed BC and they are a tougher gulided monometal. They dont shed thier petals and expand to a more blunt, flat and larger frontal than the TSX's. They are also very accurate in my 300 RUM.

Re: 300. Win Short Mag

Here you go. I have found many good shooting loads, but the most notable loads are listed below. These loads were developed in my Browning Stainless Stalker 300 WSM. Both loads are extremely accurate and they may be hot in your rifle, be careful. Both of these loads have produced .25 inch groups. I have many loads in the .75-1" range, and I can give you that info too if you need it.

The SST is a fantastic deer or light skinned animal bullet, it's not nearly as expensive as the premium bullets, and it has a decent BC for longer shots.
The E-Tip is a true premium bullet that is suitable for any north americam game. Relative to the SST, they're expensive.

180 Grain Hornady SST
Federal or Winchester brass - both work well with this load
H4350 Sweet spot found between 65.5 and 66.0
CCI 250 primer
2980-3005 fps depending on your powder charge
COAL 2.860, just to give enough clearance in the mag box.

180 Nosler E-tip
Norma Brass
RL17 Speet Spot between 66.0 and 66.5 grains
CCI 250 Primer
3085-3110 fps depending on your powder charge
COAL 2.820, these like to jump a bit in my rifle.
