I have an old Aya shotgun and would like to know if it is safe to shoot modern lead shots (mainly #4 & # 6 for pheasants) in this gun. The proof mark says 850KG.

Also the left and right side of the action has two small extensions (like ears) that goes on the outside (left and right) of the barrels when the barrels are closed, does it serve any purpose? Do all guns with cross bolts type locking mechanism have them?







Thanks

the 850Kg may be.85Kg barrel weight.what bore is the gun?the ears are side clips&probably dont do much but cost more.

Thanks KimR,

Its a 12 gauge. There is another mark which says 1370 gmos which I think probably is the weight.

I believe that is proof pressure, about 12 ksi. Should be good for any factory lead loads. I would stay away from any steel loads as it is very easy to bulge chokes on the older guns.

1.37Kg makes more sense for 12b bbl weight.

These 'extensions' are refered to as Side Clips.

It is generally held that side clips don't offer much additional strength. Their original function was to keep the barrels from moving laterally. Now I think they are there just for looks.

I believe that 850 kg is the proof pressure for the barrels of your AYA, If this is the case then it is the CIP proof standard.

650 bars is the standard CIP (British and European) service pressure for shells designed for guns proofed at the CIP standard of 850 bars.

If you use "standard" velocity and pressure (up to about 10.500/11.000 psi) lead loads, and stay away from high velocity (and pressure) loads your gun should be fine.

If you can post a picture of the proof marks on the action, and the bottom of the barrels, maybe I can find out something more about your gun.
