I lack both the scientific expertise of a Bryan Litz-type feller as well as lacking the field, on-game at-range experience of a feller like Broz to substantiate my opinion.From the same rifle on average we get 3100+ from a 180 H VLD and 2950 to 3000 from a 195. In side the effective limits of a 7mm for hunting its about a wash, in my opinion.
However, my complete lack of a reasonable, substantive rationale does not impede my hubris!
In my obviously humble opinion, i believe anything more than 180grs in a 7mm/.284 bullet is just too much weight - regardless of whether there is enough powder to push it fast.
I think 180grs in 7mm is the threshold of diminishing returns in terms of weight as well the necessary velocity to push something that long to effective velocities.
It seems to me that bullets which approximate pencil length just is not optimal for shoulder fired rifles - regardless of caliber.
