The scope base is the attachment interface on the rifle's receiver, onto which the scope rings or scope mount are fixed. Early telescopic sights almost all have the rings that are fastened directly into tapped screw holes on the receiver, hence having no additional scope base other than the receiver top itself.
In the 18-pound (8.2 kg) rifle used by Accurate Reloading this would result in recoil energy of approximately 160 ft⋅lbf (220 J). This is more than ten times the average recoil from a .308 Winchester which is a common hunting calibre, and more than 4 times the recoil of a strong .45-70 Government round.

A quick look at the .45 GAP (which is loaded to .45 ACP +P pressures) shows that the 185 grain bullet is pushed to 1090 fps, for 488 ft. lbs. of muzzle energy; .45 ACP +P should be equal to or (since it can use a slightly slower, less dense powder) slightly ...
