Roskoe, you need the Lee shooters program down loaded into you puter, then you can get this info for any gun you want for about $10.00. Asuming the guns weigh about 7.5 lbs each, the 7mm 08 should have a free recoil velocity of 11.2 fps and a free recoil energy of 14.6ft lb----- the 7mm mag should have a free recoil velocity of 12.2 fps and a free recoil energy of 17.3 ft lb. I hope this helps, Glenn I think the price may be a little misleading that I qouted above, the program cd cost ten bucks .
