I have a lot tougher time shooting 2" DAH than I do shooting 3" DAH.

That said, nobody fears me at the range with my Nitro, that is around 2 7/8ths DAH.
I get a real bird with it, here and there. But, I suck shooting clay targets with it.

Someone above posted a point about pitch, something I have found to be pretty important for me to have some kind of success when shooting. I prefer between 1" and 2" measured pitch, and if it sneaks out much beyond 2", the gun starts to kick too much.

Joe, I'd not be too intersted in a 16 gauge double at 7 lbs. My 12s are all around 6 lbs. These are hunting guns, not clay target guns.
If I am going to shoot 100 rounds of clays, I likely use a pumpgun.

Best,
Ted
