Got to searching his contributions on the M71 and M64 stocks shaping/design development.
Stumbled onto this posting:
"Killing power debates aside, Townsend Whelen and Ned Roberts both wrote of the 32 Winchester Special as having slightly better accuracy potential due to the rifling twist."
I take anything Whelens said/wrote as the gold standard.
So its worth digging deeper on these twist rates and bullet weights.
Also does anyone consider the 32 special ammo "as popular" or close-to for On The Shelf ammo???
I think it gives up some range with lesser BC but it should hit slightly harder.
I'm pretty well set on 30-30 but had to read that now
