How many of you hunters, shooters, reloaders have experience with the 270 wsm? Out of the experiences, I would be happy to hear anything that you all have found out as far as powders, bullet weights, cases... anything that you have discovered.

Thanks
Croberts

I've seen it at the range quite a bit and talked to the owners.

I would stay in the 140gr.+ bullet weight area because of the velocity from the guns I've seen. That round is a wonderful cartridge and I really think it has a lot to offer to a hunter.

Quite a few Idaho hunters I've met have gone from their 270 win's to the WSM and they can't say enough good about it.

The way I see it, it's a cartridge that will give you 270 WBY velocities and better in a gun that is slightly lighter than a 270 win.

To me that equals a perfect deer rifle even though it can be used for so much more.

Just to note, I have not heard any negatives about it.

Velocity Averages (Just something to look at):

130 gr Bullet:

-270 win: ~3120fps
-270 WSM: ~3260fps

140 gr. Bullet:

-270 win: ~3025fps
-270 WSM: ~3160fps

150 gr. Bullet:

-270 win: ~2920fps
-270 WSM: ~3040fps

Hopefully someone with some trigger time can add to this thread but this is what I've got from some light research.

Overall, Great cartridge!

FOr whatever reason, I was never able to get mine to shoot well. To say it equals a .270 Wthby is a stretch, though. I load for my buddy's .270 Wthby and it gets 3500 FPS with a 130 gr.

The .270 WSM is, in my experience, a picky round. Necksizing, for example, does not work with the WSMs. Since they are already loaded to the max, you often get stiff bolt lift with factory ammo.

If you get a rifle that shoots it well, it is a step above a .270 Win and it would be a great deer, antelope and sheep rifle.

I simply love my .270 WSM !! It will probably go with me to the grave. I bought this for deer and antelope only since I have lighter and heavier calibers for different game. I found it to be extremely accurate. I use only one load, a 140 Nosler Accubond at 3200 fps. This load gives me groups everytime I go to the range on the .25"-.30" MOA. I figure that's all I'll ever need for deer and antelope.

Guess I have to toss in my 2-cents' worth. All of my experience with short and super-short mags has been negative. Although two Brownings in .223 WSSM and .243 WSSM ended up shooting well, the amount of work it took to arrive at that point was far more than I've experienced with "standard" calibers I've worked up loads for. My biggest gripe was voiced by Calif. Hunter---stiff bolt lift, and I had to bump the shoulder every time I resized or the bolt handle wouldn't go down. Something was crazy with the .243 as well. As I was working up the first load and was 3.0 grs below max charge, the load chrono'ed 245 fps faster than the value shown for the max charge. Never figured that one out, but sure backed off the charge some more, even though my numbers were good per the loading data.

And, obviously other gunners have had good luck with them as indicated in the previous post.

What powders seem to do well in your rigs? Slow fast ??

Croberts, the 4831's (regular and short cut) both work well for me, as well as IMR 4350 and Win 760. IMR 4350 is my favorite, great blend of velocity and accuracy.

I have had ZERO problems out of my .270 WSM's. That is for 5 of them, 4 SAKO 75's, and one A-Bolt. I have seen the issues a few described (sticky bolt) in some Kimbers and one Model 70.

The round is capable of meeting and exceeding the Roy if the barrel length is the same. Folks have a way of forgetting the longer barrel that is typical on Weatherby's when comparing velocity. My pact chrono (lie detector) gives me consistently higher speeds with my WSM's which have the same length barrels as my Weatherby when loaded comprably.

The one interesting thing I have seen is that my rigs all shoot better with MORE jump to the lands. They round is NOT picky at all about it's recipe, I've got several loads for each rig that will shoot well. I have noticed on the rifles that I have recorded enough data on, that they slightly prefer near max loads.

My SAKO's all feed well, I've got standard cartridges that are better for sure, but no problems with my M-75's. My A-bolt went back to the factory for feeding issues, it was OK except for a few shorter blunter bullets i.e. the Fail Safe. Don't know what they did, but it worked fine after it came back. That rifle is on the trading block though, I just really prefer my SAKO's across the board. I've only got 3 (all the SAKO's) that will feed an empty case--don't suppose that matters, I've got standard long action cartridges (a 375 H&H for example) that won't either.....

The three bullets I shoot with great results are the 130 gr NBT, the 140 gr AB and the 130 gr XXX.

My typical load is Win brass, CCI or Win LRM primer and near max of IMR 4350.

I've taken some really big Whitetails at long range, and it really does the trick. It is also magical on Antelope with the 130 NBT.

Good Luck--Don

I have a NULA 270 WSM and it has become my favorite rifle. Very accurate with just about anything I feed it; but particularly with 130 gr. TSX and 140 gr. Accubond at maximum loads.
Even shoots 90 gr. and 110 gr. bullets very well. First and only 270 caliber I have ever owned and I wouldn't part with it.

I found the same thing. I started out seating close to the lands and the groups didn't start to tighten until I hit .050" off the lands. I finally settled on my current load which is a Nosler Accubond 140 seated .070" from the lands, Winchester brass that has been flash hole uniformed and trimmed, Federal 215 primer and 70 gr of Magpro. Magpro has worked great for me but it seems to work best with 140 gr bullets.
