Re: .243 Win 87gr. V-max ?
You may not be having more pressure.... you probably aren't.
I ran a test with a bunch of 308 rifles some years back, and 100 rounds of Federal Gold Match, all the same lot number.
The velocities ran from 2545 to 2715... all with the same load - and the longest (27.5") and the shortest (24") gave the highest velocities... the 26" barrels gave the slowest velocities.
If you have no pressure signs, don't worry.
