Unless my memory has tanked, I still have a magazine in which JOC wrote and gave results from comparing
the 270 W with a 7mm RM. In this article he used a 22" bll on the 7.
He preferred the 270 w/22" over the 7 RM w/22".
I have both 270 (s) and 7 RM (s) and 24" barrels don't bother me 'none'. I never notice the diff.
I do have 1 rifle with a 26" bll and occasionally I notice that length IN my truck, otherwise when hunting.....
bll length doesn't bother me.
