**7 wsm loads**

[Sportin Wood]

The 7 WSM needs its own little reloading data thread, especially since I'm on the verge of building a lightweight (hopefully) for hunting. Anyone running a 7 WSM please post up your loads here. As always, readers please use caution when using others loads. Start low and load up. Thanks guys!!!

Heres a few that were mixed into the 7mm thread:

7WSM

175 smk; 65.0 RL25; Fed 215M primers; Win brass; OAL 2.86"; 2,900fps 26" Kreiger 9 twist.

175 smk; 66.4 H1000; Fed 215M primers; Win Brass; OAL 2.86", 2,875 26" Kreiger 9 twist.

63g H4831 2940FPS
63g RL22 3027FPS
67g H1000 3011FPS

All loads were a little hot, not really to bad though. It was freezing and altitude is high. Im going to dial down a couple grains and see how velocity holds up. H1000 and RL22 seem to hold better groups.

Been shooting this load for the past 400-500 rounds without a problem. Not even measuring to the lands. I think last time it was .140 thousands. Don't shoot at 100 for groups that often, but when I worked up the load the group was .3 something with 3 of the 5 in almost the same hole. Mounted a new scope the other week and got a zero. Only shot one group at .285, not too shabby IMO.

New barrel already and new load.

Seated out to the lands it was pushing 3015FPS with a SD of 6.

I also have a mag feed load that is friendlier on everything. 64gr of 4831SC with a 2.960 COAL pushing it slowly at 2861 with a SD of 7.

Cci 200
produced .441" three shot group during load development (54.5 gr was not bad either)
Still working with this one, and I would like to try a slower powder.

I have also been working some loads with the 140 partition. Has anyone obtained great accuracy with the partitions?

Caliber: 7WSM
Action: Surgeon 591
Barrel: 1:9 24"
Stock: T5A

Load Data:

Brass: Win
Powder: RL-22 @ 63gr
Primer: Fed 215M
Bullet: 168gr Berger VLD
Seated: 2.905 (Will fit in a AI mag)

15 rounds fired consecutively over the chrono:
Avg: 3089 fps
SD: 7 fps
ES: 21 fps
~.25 MOA

This is a max load in my gun. It is also temp sensitive above 85 degrees.

Edit: 3/21/12

I have went back and modified this load as it was a little too hot. It was killing my primer pockets in 3-4 firings. Here is the new load that has been modified.

Same Rifle/Same components
61.5gr of RL-22
168 Berger VLD

Avg Velocity: 3000fps
SD: 3fps
ES: 7fps
This is from 10 shots fired over the chrono.

Accuracy is still sub .25moa.

Due to the temp sensitivity of the RL-22 I decided to work up a H4831SC load in hopes that it would be less temp sensitive. With the RL-22 I saw a ~100fps increase in velocity from 70* to 89* in the direct sun. Also a noteable pressure increase as well was seen on my brass.

I worked up this load:

Same rifle/components as above.
62.9gr of H4831SC
3,032fps average with the 168gr VLD from a 24" barrel
ES: 12fps
SD: 5fps
Accuracy was literally 5 shots in one ragged hole at 100yds. This workup was done in ~75* temp. I am curious to see how this load reacts to 85-95* temps in direct sunlight.

7WSM
Winchester brass
Wolf LRM primers
2.96" COAL
Berger 180 Hybrids pointed and BN coated
26" GAP chambered barrel
62 Grains RL-17
3050 fps 3 shot average

I have a 7WSM built by GAP on a Surgeon 591 short action and 24.5" Bartlein 5R.

180 gr Berger VLD
62.2 gr RL-22
Fed 215M primer (large rifle magnum)
COAL approximately 2.951
OAL to Ogive (touching) 2.241

No pressure signs at 62.2 but started to get some sticky bolt lift once I got up into low 63s.

Rifle has produced several sub-.25moa groups, and gets out to 1,000 yards with 7.2 mils of elevation at 1990 DA.

Will post my 180 Berger w/H1000 later

Good info guys. I might be building a 7wsm in a short action in the near future. I want to go as short as possible on the barrel and my goal is to send the 168 berger to at least 3000 fps.

How short can I go?????

I can push both of these loads a little more but they have performed very well and do everything I need to do for hunting.

7 WSM

176 Cauterucio

66.0 MagPro

F210M

Avg - 2880 fps from 24" 1:9"

Could run them faster, but the extra velocity added no extra accuracy, so kept the foot off the gas to stretch barrel life.

Hello all - anyone running the 180gr eld-m in their 7wsm.

Hello all - anyone running the 180gr eld-m in their 7wsm.

I have run a few hundred of these now. Great bullets that make great rounds. Zips right out to a mile to touch a 24" target no problem.

crc1028 thanks for the update - what twist are you running?

I'm end of summer busy and haven't had a chance to work them up yet but hopefully soon. Will report back & thanks.

 

[Roadkill4us]

Finally got out for a little while this weekend - elev 5880 temp 60 avg vel 2880 26" barrel suppressed 7wsm with the 180 eld-m. This was using h4350 only did 100 yrds but it was shooting great. 1/4 to 1/2 when I did my part. Will try to take to distance and see if it holds together. I see guys getting higher vel with other powders and wonder if it's worth chasing? Do you think I will be getting good use of the BC or do I need to run faster to take advantage of it. Thanks for your thoughts.

Anyone have some load data for copper/nonlead bullets? Planning on testing on hammer bullets since I'm in SoCal for hunting.

 

[2treeline]

Anything for Berger 190 at 2.950 COL?

Anyone shooting 166 ATips ?
