OSP Shooting School's Gil Ash breaks down a crucial shotgun stock modification. 👨‍🏫

Gil Ash from OSP Shooting School explains the concept of 'third dimension cast off' in shotgun stocks. This refers to the bending of the buttstock, typically achieved by heating and shaping it, to correct for the shooter's shoulder pocket and eye alignment. Proper cast off ensures the shooter's eye is aligned with the gun's rib when mounted consistently, leading to more accurate shooting.

Quick Summary

Third dimension cast off in shotguns is a lateral bend in the buttstock, achieved by heating and shaping. This adjustment corrects the offset between the shooter's shoulder pocket and eye, ensuring proper alignment with the gun's rib for improved accuracy. A consistent gun mount is essential for a gun fitter to achieve an effective gun fit.

Frequently Asked Questions

What is 'third dimension cast off' in shotguns?

Third dimension cast off refers to the lateral bend or 'warp' in a shotgun's buttstock. This adjustment is made to compensate for the shooter's shoulder pocket and eye alignment, ensuring the eye looks directly down the gun's rib when mounted.

How is shotgun stock cast off achieved?

Shotgun stock cast off is typically achieved by heating the buttstock using methods like hot oil or high-frequency infrared. The heated stock is then placed in a jig and bent to create the desired warp.

Why is a consistent gun mount important for gun fitting?

A consistent gun mount is paramount for effective gun fitting. A gun fitter can only provide an accurate and beneficial fit if the shooter can consistently mount the firearm to their shoulder and face in the same way each time.

What is the difference between cast off and cast on?

Cast off means the shotgun butt is bent away from the shooter's face (usually right for right-handed shooters). Cast on means the butt is bent towards the shooter's face (usually left for left-handed shooters), correcting for opposite shoulder/eye alignment.
