Goatbrother,
I hadn't thought of doing a by caliber comparison, I will look into that. I was just wanting to see if all the claims of modern inlines being equal to CF rifles had any validity, so far I find that none are comparable to a CF in terms of Point Blank Range unless you compare them to the 30-30 or 35 Rem. Even many sidelocks compare to those two calibers when shooting something other than a PRB at typical hunting velocities. As for the 7mm to ML comparison you mention, here is an energy comparison for my 175gr 7mm load to the BP Express with a 300gr SST. Muzzle 3497/4163, 100 yards 3051/3161, 200 yards 2652/2356, 300 yards 2296/1735, 400 yards 1979/1269, 500 yards 1697/950. The BP Ex starts out higher but drops quickly compared to the 7mm. The trajectory isn't even close with the 7mm being down about 32" at 500 yards (6" PBR sight in) and the BP Ex being down 84" at 500 yards set up the same way.

Nchawkeye,
Your SST load, according to my ballistics program, is going around 1600fps and would give you a 6" PBR of around 153 yards. It drops to 1000FPE at about 95 yards and to 700FPE around 205 yards. The round ball load worked out to about 1500fps with a 6" PBR of 125 yards, 1000FPE at 11 yards and 700FPE at 47 yards. Your shot of 115 yards still had 457FPE at the target. These numbers are approximate based on your info.
