7mm-300 Winchester Magnum Experience?

[nyrifleman]

Necking the .300 Win Mag down to 7mm has me intrigued. I googled this wildcat, McWhorter rifles seems to like it.

What I'm looking for is any real life experiences with this round.

I'm considering a build on a M-70 Classic Stainless with a 24" barrel.

>100fps faster than a 7mm wby. and a whole lot cheaper to shoot. Not quite the performer of the 7mm ultra but much more efficient and less recoil. McWhorters told me they are getting 3150fps out of 180 Bergers. I have already ordered the action. McWhorter will be building mine as soon as all the parts come in.

With what length barrel did McWhorter quote those velocities?

Here is a link to the thread on the one I have been working with. I will build another... awesome round!

Anyone own a 7mm 300 Win Mag?

Allan at McWhorter Rifles told me he was getting 3150 with a 26" barrel.

Jeff,

Thanks for the attempt, but I think you forgot something.

As close as I can tell with my Chrony and using what matches the drops in my exbl program I am getting 3175 ~3180 with 180 Bergers and a 28 1/2" barrel.
