My 7mm RM barrel is 2 inches longer than my 280 Imp. I should have noted that in my difference in velocity estimates, since that would give a barrel length advantage to my 7mm RM over my 280 Imp.
Thanks .280Rem for bringing that bbl length issue up, since it plays a role. The Tikka Lite barrels are 24 3/8 inches long in 7mm RM, the same as their 300 WSMs.
