It's gotta be the .35 Brown-Whelen,I'm on my second one. The first was on a commercial FN 98 with 23" Brownells barrel,it shot quite well.
The current one is a push feed Win. 70 with 23" Lilja SS barrel.This round comes within 5% of a .338 WM and less recoil.
200 gr. bullets for the little ones,250s,280s and 300s for the big ones.
