DINK: I was not really responding so much to you or singling you out,but just needed somewhere to start....
In the case of the 180 in the 7 mag and the 180 in the 300 winmag,I suspect the powder charge would be lighter in the 7RM than in the 300,at max charges for both,and the 180 7 mag load could not be pushed as fast as it could in the 300 so in equal rifles my guess is the 7 mag would kick a bit lighter...
