Just wanted to drop an update on this old thread since this ball is rolling pretty good now.... and I'm all giddy & can't wait to start shootin!
After much deliberation & conversation with Mike Bellm, who seems to be the TC/CVA authority, I let him talk me into a .35 Brown Whelen. Mike did all my barrel work and also provided some custom dies & some fire formed brass. I just picked up a new frame, disassembled it, and sent it off to Jim "Shots" Hendershot Sr. to have the trigger work done. When it returns next week I'll be putting it all back together with some more goodies from Mike Bellm to tighten things up, and mounting a Vortex Viper HS 4-16x44 LR on it that I just purchased online. Then it's time for load development!!
The brown whelen is simply an improved 35 whelen isn't it?? There really aren't huge capacity gains to be had blowing out the whelen but I suppose it could net you another 100 fps. I'm using rl15 and a 220 speer in my standard 35 whelen going a bit over 2700 fps of that helps.
