A 10.75 pound 500 NE is within my recoil tolerance.

A 9.5 pound 458 WM is within my tolerance.

A 10.5 pound 450-400 3 1/4" DR is within my recoil tolerance.

A Marlin Guide Gun (45-70) loaded with Garretts or the like is above my recoil tolerance.

Could shoot a 9lb 375 H&H all day as long as the stock fit me.

Like has been said before... It is about stock design/fit and concentration up to a point, IMO.

500Nitro,

Would love to see any pictures you have of the Lang 500 you mentioned. Do you still own it? When was it built?
