NOTE: Long Action Only The M77L is not suggested for the following caliber power factors

Use this formula. Multiply bullet weight times velocity. If you exceed a power factor of 500,000 the M77L will not hold up. You will need to use our new M77LX mount.

Example: .338 Win Mag.... Bullet weight 200 gr...Velocity 2950 fps..... 200 x 2950=590,000 this exceeds the M77L mount capability the M77LX would be required
