7 wsm or 7 LRM

I am currently in the process of building a new rifle and I can't decide on exactly what to build. I have narrowed it down to either a 7 wsm or the 7 LRM. I have a Krieger 27" 1-9 twist barrel. My goal is to get around the 3,000 fps mark with the 180 gr bergers. What do you guys think?

I would go with the LRM. I think 3000 fps with the 180 is a little out of reach for the WSM.

What is your opinion of the 7LRM from an accuracy standpoint compared to 7 wsm?

The cartridge will not make a difference in accuracy. Accuracy depends on quality of components and smithing as well as good load development and finally the shooter.

Re: 7 wsm or 7 LRM

I have a 7mm wsm 26"brux 9" twist. Its a freek bbl in that I get 7mm stw velocities out of it ? 69grs of Re# 19 behind a 139gr sst produces 3500 FPS . 65.5 Re#22 3160fps 162 gr A-Max . But how accurate is it ? MOA at 600yds . I need a better trigger ,but this caliber for me is a keeper. nothing wrong with my Chronograph. tested other known guns through it that day It measured those as to what they should be.

You'll get the best long range performance from the cartridge employing the most powder capacity. The WSM is a fine cartridge, but it will not run with the LRM when comparing apples to apples. The WSM might, emphasis on might, get you to 3000 fps with a 180, but the LRM will get you to an easy 3150 fps with the same bullet.

one of my shooting buddies is using 65grns of RL33 behind the 180 berger in his 7WSM match rifle and is bumping 3000fps with no pressure in a 27" tube. so yes it is possible
