shortactionsmoker;
Good evening to you sir, hopefully this finds you and yours doing acceptably well.
A short while ago I started a similar thread - I was going to say parallel, but perhaps that's overstating it some.
Anyway here's a link to that one should you be interested in reading the responses.
https://www.24hourcampfire.com/ubbth.../Tissue_Damage_270_vs_6_5x55#Post9248055The highlights for me were that when I finally measured the twist on the .270 barrel I was using it was slower than normal. That coupled with sluggish velocities for a .270 and my using TSX/TTSX/GMX bullets made for less than stellar performance - for a .270 anyway.
Anyway I believe enough in faster twist enough that I went to the garage, unscrewed the barrel and that action is at the gunsmith up the valley as I type this - having a fast twist 6.5x55 barrel installed.
Hopefully that was of some use to you or someone out there tonight. All the best to you and yours in this Christmas season.
