[joshiwa220]

I am liking the idea of a 7 lrm. What steps are need to neck the 375 ruger brass down to 7 mm. Does it need trimmed during the process? What dies are recommended?

Look into 7mm Dakota. I believe its similar to what you are trying to do...and already done.

joshiwa220,

Go to the other thread you started on rifles barrels and ballistics to read how I necked down the 375 Ruger to 7mm. http://www.longrangehunting.com/forums/f19/7-375-ruger-7-lrm-84543/
