Ok so im about to start working up a load for groundhogs, paper punching and maybe deer later. its a 7 wsm based off a rem with a 24 in shilen. 1 in 9 twist. would like it to be pretty good out to 1000 but that will mostly be for groundhogs and paper. deer maybe out to 7-800. the question is what powder should i run for 162-168 grain bullets? i have heard good things about magpro but have never used it and also 4831sc. any luch with the reloader series? also, what bullets do you like. im looking at matchkings probably 168, amax and sst's.



thanks,

matt
 
Re: need some 7wsm advice

H4350 is a good one in my 7 SAUM (which is very close to the WSM)

I've had decent luck with 162's over H100v as well, and RL22 is definitely something to keep in mind for those bullets.

The 162 has a better BC than the 168 Berger does, if you're going to put out the cost for the Bergers I'd go with the 180.

I shoot 139 SST's for deer, 162's and 180's for paper/steel.
 
Re: need some 7wsm advice

r17 seems to be made for the WSM! 62.3gr r17 gets me 3150 in a 24" barrel running the 162amax
 
Re: need some 7wsm advice

wow thats quick. rl17 might be top of the list right now then. im gettin fairly good results with rl25 in my 257wby sub moa. i think the 180's will finish out to long for standard mag box. im leaning towards 162 amax. cheap, high bc and supposed to be accurate in most guns. 3000 fps with low deviation sounds good to me. 3100 wouldnt be bad though. just burn out the barrel a little quicker. thats why they make new ones though. lol
 
Re: need some 7wsm advice

I'm running Berger 168 VLD's ahead of 61.5grains of RL-22. Pretty mild load at 2800 but the SD is less than 6 fps.

Be careful with the RL-17 I've seen some denotation problems with a 6.5-284 and a WSM has quite a bit more case capacity which could really make things interesting.
 
Re: need some 7wsm advice

is 4831sc very temp sensitive? that is fast for a 180. so if im leaning towards 162 amax to start what powder is going to give me the best results. would like a speed arround 3k. i like the idea of the speed with rl17 but kinda dont want to blow up.
 
Re: need some 7wsm advice

I'm interested in the results too. I a 7wsm in a 1 in 10 twist. I'm looking at pushing 162 A-maxs but haven't had much time to do so. Anybody trying Sierra MK's?
 
Re: need some 7wsm advice

I believe Magpro and RL25 are going to be the speed kings in the 7WSM. I have tried RL25 with decent results, but now I use 4831SC as it's just more accurate in my rifle. I believe that is what Jered at APA and George at GAP uses in their rifles as well.

As for projectiles. I would use the 162gr AMAXs if they would shoot well out of my rifle. Good BC, can hunt with them and can be pushed really fast. Fast enough to shoot inside of the venerable 180gr Bergers out to 1k and a little beyond. The Bergers and JLKs are pricey, but boy do they shoot well.
 
Re: need some 7wsm advice

I'm shooting a 168 gr Berger w/ 66 gr of 4831sc. Getting about 2950fps. Shooting a little under MOA. I need to try the 162 AMAX, just haven't gotten around to it yet.
 
Re: need some 7wsm advice

I'm running 64.0gr H4831SC with moly'ed 162Amaxs. ~2960 from a 24" 9 twist Broughton. Have worked that combo up to 3050, but lost a little accuracy and started flattening the WRLM primers a tad...

The Amaxs are cheap, available & shoot great. And as Baccarat pointed out, you can push 'em hard enough to where the big 180VLDs don't catch 'em til after 1K...
 
Re: need some 7wsm advice

Im shooting 162 A-Max's over RL22.

here is my load, but let me warn you, the 162 A-Max touches the lands on my rifle at 3.118" so I have extra room for more powder

162 naked A-Max
Win case
65gr RL22
215M primers
3.118" OAL
3150 FPS
1/8 moa accuracy.

Other than the OAL I use the same load at 64.5....great results
 
Re: need some 7wsm advice

I shoot 162gr Amax's w/ h1000 @69.2gr,I'm getting 3030fps,shoots sub MOA.
 
Re: need some 7wsm advice

ok i feel a little better now. i was trying the kirby allen method of working up a max and got to 65.5 without any pressure signs. ran out of loads, didnt think i could get that high. so should i keep going. made a batch of 64 gr loads but they got a little over an inch group. previous owner gave me some 162sst loads that were arround 62gr and they shot great. i think seating depth is killin me with the standard short action mag box. i have them seated to where they just fit by a hair.
 
My barrel is a 1 in 9 twist and it shoots the 180 Berger VLD better than any other bullet out there. I run RL22 and get 2960 from a 26" barrel. It is actually pretty easy to get over the 3000 FPS mark with 162/168 class bullets and I would look at the H4831 or H1000.
 
My shooting partner has a Surgeon Scalpal with a 1:9. I load for him. With the 162 amax I used 62.3 h4831sc. A little on the "hotter side" but it will literally put then in the same hole at 100. I also loaded up some 180 bergers over vn560. AMAZED. I don't remember his dope at 920 yards from a. 100 yard zero but lets just say we were both amazed. FLAT!
I'm not an expert for the 7wsm, but for the 162 and 168 , H4831sc is the best powder I've tried. I have to admit ... This is one of those rifles that will pretty much shoot anything.. That being said , from a 26" bbl , he's getting right at 3,000 fps from the 162 amax load loaded at SAMMI length. It makes my 6.5 GAP look like a pea shooter at 1,000 yards. Not that my GA wont outshoot it , but as far as being a "laser" , I think that assessment is spot on.

It does?

I know Hornady advertises the 162amax @ .625, which is higher than the 168vld's .617, but I thought the .617 of the VLD was "real" and the .625 of the amax was "claimed"...?

No disrepect intended whatsoever, I trust your testing and workups...just curious to hear what you had to say about this.

3 + Years Ago When I Made That Comment The Berger 168's That I Had To Test Were FromAt Least A Year Earlier And Were Part Of The Old Orange Box shape Lots With A Lower BC. today The Statement Requires A Qualifier To Compare The Latest Generation Of Bullets.


So Based On Todays Data Available You Are Correct, Based On The Data From Early 2010 With 2009 Our Earlier Bullets, My Statement Holds True.

Hadn't noticed the date of your post. Had I, I wouldn't have quoted/posted... Sorry.

Anyway, thanks for clarification!
