    Other than maybe reduced recoil, does a .740 bore have an advantage over a .735 bore or is .750 bore best of all.

    I am a little confused as to why the premier trap gun makers utilize different bore sizes.

    The big bore barrels can decrease the number of fliers in the pattern. This is because of less shot deformation. HMB

    Thanks hmb, I had not considered the reduced flyers. Do some of the TG makers use a larger bore than .750 that you know of?

    Would .755 be better, is there a point of diminishing return? I am just curious about this.

    Thanks

    I do not understand how a larger bore will reduce recoil unless velocity is reduced.

    When they market something, they market what sells best. Don't you find it strange no one can agree on what size overbore works best? GAP

    If the bore gets to big I understand there can be problems with the was sealing the gas behind the wad --- with a reduction of velocity and perhaps poorer patterns as some gas could be ahead of the wad and could let it come out of the muzzle slightly cocked.

    Several years ago, I had a M-32 Krieghoff 30" barrel set that had been overbored to .755". It had fixed chokes, tighter and tightest. It was the best Bunker barrel I have ever shot. Even with the Heavy Dove Load, 3 1/4 X 1 1/8, recoil was very acceptable. At the time, you could get a flat of them for $30. Of course, the gun fit me, or it would have kicked my head off.

    I let Les Greevy talk me out of it. He set it up for a student. He was impressed with it, as is everybody who shoots it.

    It seemed to put about every pellet on the target.
