Well here you go:

165gr Sierra GameKing BTSP 30cal bullet starting out at 2400fps will be traveling 2203fps and have 1778fpe at 100 yards and at 500 yards will be 1516fps and 842fpe.

165gr Sierra GameKing BTSP 7mm bullet starting out at 2400fps will be traveling 2226fps and have 1815fpe at 100 yards and at 500 yards will be 1606fps and 945fpe.

So, the 7mm bullet has a higher sectional density will have more retained velocity and energy at any yardage and therefore will have more killing power. Will it deliver more shock, given the fact that they are as close to the same bullet as far as design and make up as you can get, I believe so.
