Whats Your Favorite 7mm WSM Load

[Yaddio]

I just went to the range yesterday with my 7MM WSM M70 Featherweight. This was my first round at the range working up some loads. Previously I had only shot some break in rounds with 160 grain Sierras and IMR-4350. These grouped just a bit over an inch. I live in Ca. so I have to hunt with non-lead bullets. Long story short, my two best loads yesterday were:

Fed 215 primers for both loads

140 grain Barnes TSX with 63 grains XMR3100, got a 1.1 inch 3 shot group

150 Nosler E-Tip with 62.5 grains R19, got another 1.1 inch 3 shot group

Rifle is pretty much bone stock, but I glass bedded, free floated and did a trigger job. I've got some more work to do but I felt this was a pretty good start and this rifle has some potential.

[QUOTE=RidgeRebel;477105]I just purchased a Winchester M70 Coyote in 7mm WSM with the laminate stock. I am wanting to shoot both the Hornady 162 A-max for long range target shooting and the Berger 168 VLD for hunting elk. I was hopping you guys could give me some good loads to start with. The rifle has a 24" barrel with a 1 in 9.5 twist I believe.


Howdy,

My Win. MOD 70 Stainless Classic (rebarreled) likes the 168 Bergers with enough H4831SC to produce 2925 fps. It produces a SD of 7 and .750 inch groups at 200 yards with that load. Bullets are seated .005" off of the lands.

Please understand the main problems if you use the Bergers!!! I had to modify all of my seating dies for these VLD bullets. I drilled the bullet seating stems out about .200 inches to get the tip of the bullet to stop bottoming out in the stems. Now, I just start the bullet in the case just a little, then put the round in the run out guage, then correct the off-set before finishing the seating process. Rotating the whole round during the seating process helps as well.

The second main problem is that bullet jump to the lands is of PARAMOUNT importance. You could use up lots of ammo to test which jump length gives the best ... most consistent... groups.

Hope this helps and best to you.

Good shooting.

So far so good. It's accurately shot everything I've fed it fairly accurately. I'm just getting started with it. With some more load development I'll get it down under an inch and lock down some good loads.

I originally loaded for my 7WSM & 168 Berger VLD with H4831SC, and it shot well, but the load seemed a little hot. I had also tried H1000 in the beginning, but missed a good node as I was working up. Went back and retested with the H1000 and ended up with a great shooting load at 69 gr H1000. WW brass, Fed 215mag primers, seated .010" off the lands.

Have tried 18 different powders now, still loves the h4831sc!!

What rifle and twist are you using. Have a buddy that has a savage in 7WSM with less than 100 rds down the tube that wants me to own it as he thinks he needs a 270WSM I have never owned/shot a wsm but may give one a try.
