I currently shoot a Beretta Silver Pigeon Trap 12ga. using 1oz. loads.

I also have a 30" 20ga. o/u barrel that fits this gun. Question: Has anyone 'out there' used this combo to shoot Trap singles or doubles using 7/8oz. or 1oz. loads? Do you see a big difference between the 12ga vs. 20ga?

Regards,

John

Usually the difference between 12 and 20 gauge is not the payload but the weight of the gun. Mark

Used both 12 and 20; the hits with the 20 were fine. However, I did have a chance to use some Rio 20 1oz and the hits were even better. Did I run them? Of course not as I seldom do. One of those skeet shooters I am.

Those reasons would include the weight of the gun, and the availability of the appropriate ammunition. Mark

For singles and doubles, my scores are the same with either load. If you miss it appears the decreased pellets are not a significant contributing factor.

Scores are the same for 'caps too, but mine are dismal enough that isn't an endorsement LOL.

Generally a 12-gauge will pattern 1 oz. slightly better than a 20-gauge choked the same will due to setback deformation in the taller column. But the 20-gauge will pattern 7/8 oz. about the same as the 12-ga. will.

Your 20-gauge barrels MAY be HEAVIER than your 12-gauge barrels, as that often happens when 20-gauge barrels are made to fit a 12-gauge frame.

Whichever one you are most comfortable shooting is probably the one you will score the highest with.

The main reason people shoot 12-ga. in the Olympics is probably that ISSF rules do not permit any other gauge.

Shows what an old f**t you are! :)

I stand corrected -- they DO allow smaller gauge guns to be used. Rule 9.4.2.1.

I'd guess no one is using a smaller gauge because they need the weight to absorb the recoil of the high # of shells they have to fire in practice and competition, and it is usually hard to find a 20-ga. that weighs enough.
