270 wsm vs 300 wsm

I am the proud owner of a Sako 75 chambered in 270wsm. I primarily use the gun for deer hunting and the occasional coyote. I am planning on going elk hunting and sheep hunting next year out west. I have been told that my 270wsm will be fine....BUT I am always looking for an excuse to get another gun.

I like the ballastics of the short mags, but don't know much about the larger calibers.

What is a good larger caliber that would meet the larger game needs I mention above?

Love the 270WSM

I have had it for 2 years and I love it. The Sako 270sm replace a Ruger 308. As far as the caliber goes, I have shot 5 deer, 2 hogs and a coyote with it and non have taken a step after the shot. The deer were on average 120 yards out. I am using 130 grain Winchester Ballistic tip and the new 150 grain Fusion rounds.

The 270 that you have would be fine. Like you said, if your like me and always looking for an excuse to get another rifle and can afford it, go for it. I don't have an experience with the short mags and don't plan on getting one anytime soon. But if your stuck on the short mag and want to take a step up, I would go with the 300 wsm. The 270 wsm and 7mm wsm ballistics are not much different to justify going with the 7mm. I would personally go with the 300 win mag, but if your looking for a short mag, I think the 300 wsm would be the way to go.

The 300 wsm would take the big boned elk and black bear. I had a 7mm WSM that will take deer to caribou. I used the Fusion round too, great expansion.Net will have very knowledgeable members there. More recoil, but more oomph. The 300 Win will do also. Bring one home and post it! Stainless barrels are the way to go with the WSM's.

Stainless barrels are the way to go with WSM? Is it because of more powder burning and/or higher peak pressure. Please explain.

I think the 270WSM will be fine on elk, use the heaviest, but accurate bullet you can shoot out of your rifle. josh

If you want a .300 mag, then the classic .300 winchester magnum can do everything that the WSM can do and then some; it is therefore the better choice.

The .270 WSM has a justification (makes sense), in that there is no other .270 mag to compare it to. But a short mag in .300 makes very little sense, because you handicap yourself in the one area where .300 mags really shine, and that is with long, heavy bullets, such as 200, 220, or even 240s. These compromise too much case capacity when loaded in a .300 short mag.

I for one have not figured out what the big deal is about the short mags. My plain old .270 and 300 winchester have been killing deer and elk just fine for me for years. I could care less about action length. Frankly I think it is mostly advertising hype and much ado about nothing.

I sure see a lot of newer shooters with them. 99% of which cannot shoot a 30-06 to its true potential, so what in the heck are they doing with "magnums"??

Of course someone had to say something about the "old reliables" being just as good as the new wsm. I don't think we can have a conversation without someone bringing that up.

I found evidence of throat erosion after about 700 rounds. It wasn't bad but I lost my hunting lease due to a friends death, so I traded it on my new Bushy. The hotter the explosion and faster the velocity, the more wear. Stainless is more resistant to this phenomenon than chromoly . It still got 1/2 groups at 100yds. If your gun can be improved by rodding with Microlon and shooting one then again and again. This will tighten it up and make it slick as owl grease. I always used wipe out on mine to keep from having to rod so much. Use that bore light often!
