I have built the 7mmwsm's on both long and short actions. This is my personal opinion, If you're going to be shooting primarily 168-180's in a repeater, the 700 long action works very well, but I feel it is crutial to use an HS bottom metal with center feed clips for positive feeding. If you use the HS bottom metal use the clips for the 300 win mag as it is a little shorter. If you use a short action I also would use the HS bottom metal. I have two different 7mmwsm reamers one is set up for the 180's and works really good for the long action and the other one is set up for the short action.meaning it has a shorter throat.
Best of luck on your project. you've picked and awesome cartridge.
without God their is no hope for this country
