Help me decide which caliber for my WSM build? ;)

I'm not sure which round I'd like to chamber my next build for, but have decided I want to use the WSM case. I'm seriously considering the 270WSM but haven't ruled out a 6.5 or 7mm. I'm not too interested in the 300, but if there's a serious advantage I may reconsider.

I've run the ballistics and I like what the 270 offers verses all the other choices. Hope to get some serious feedback and real life stories/examples of why one is better than another.

I plan to use this rifle for hunting anything on 4 legs I'll encounter in the Northwest (WA).

The 270 WSM is the most versatile IMO, I shoot laser flat 110 TTSX at 3600 fps for coyotes and antelope then I shoot 165 or 175 gr Matrix VLD's in the mid 3000's for long range elk slap down. Norma brass it excellent!

Re: Help me decide which caliber for my WSM build? ;)

I love my 7WSM so I'm a little biased. It really comes down to what you plan on doing with the rifle. Is this a hunting or range gun? If for hunting (which I'm guessing it's going to be considering this site), what type of game? What kind of range are you looking to shoot at? Do you reload?

If you don't reload, I'd say the 270 or 300 simply because trying to find 7WSM in factory ammo readily available is a pain for some reason (this was a major reason for me learning to reload). This would also rule out the 6.5 or 338 since I don't think (not positive, but pretty sure) anyone makes factory ammo for them. If you do reload, there are more options for good bullets with high BC with the 7 or 6.5. There are some bullet manufacturers coming out with new high BC 270 bullets, but there are a lot more for the 6.5 or 7.

These are just my opinions, there are plenty of people I know who love their 270 or 300WSM's. I'm sure many will disagree with me, but it's kind of like asking the old ford/chevy question. They are both good but it all comes down to is personal preference.

Re: Help me decide which caliber for my WSM build? ;)

If you're serious about making a true long range big game hunting WSM, my vote is 300 WSM in a 26"-28" barrel running .719 BC 230 Berger OTMs at around 2750 fps. The long range energy of the 230 is phenomenal in this round and it takes the 300 WSM to the next level over its little brothers. Plus, you'll likely have better barrel life. Get a muzzle brake regardless of what you decide.

I live in your area now and I can let you test drive this setup on some steel targets and you can see first hand what 2000 ft lbs from a WSM at 700 yards looks like.

300WSM is what I shoot.

As said, if you want to be able to purchase 270 or 300 is the only way to go.

I prefer 300 because of the range of projectiles.

I have a 270Wby and for pure hunting the caliber is fine.

7mm has projectiles but no ammo to purchase.

I'm partial to 7 WSM because I reload and I like the bullet weight choices. If you are not a reloader, my choice would be the .300WSM.
