Plus one

I can believe that. RL33 would work even better in the LRM. To reach 3000 fps with a 180 bullet in the WSM is pushing it to the limit and with most powders and barrels it's not gonna happen. It's much more doable in the LRM.

Re: 7 wsm or 7 LRM

i guess I better let him know that it just won't work eh. Gosh, to bad he has been doing it all summer long since we started playing with the RL33. And here I thought we were on to something. I probably better stop shooting 3000 fps in my edge with a 300 grain SMK also because you probably say its not possible either......young fella...beleive it. RL 33 is amazing stuff

Here is old article about the 7 LRM

Gunwerks 7 LRM???

Re: 7 wsm or 7 LRM

Thanks for all the input. So considering the following what do you guys think? Is the LRM worth it or should I just go with the standard WSM?
1. Availability and quality of brass available.
2. LRM brass proprietary to Gunwerks.
3. Cost of Brass triple that of Winchester.
4. Barrel life?
5. Let's assume 300 fps muzzle velocity difference between the two.

I would assume you did little research on the 7LRM as to the cost before considering that case vs 7WSM.

I just got new 270Wby from gunsmith last week cost me almost $2 per case and my 270 case cost 1/4 of that. If this is your first build might want to pick something little easier on the pocketbook.
