Trap, IMO, puts a premium on "stable" gun dynamics. That is, high mounted swing effort (high MOI at shoulder). When shooting a gun with much lower swing effort, one must be much more accurate. Trap is, by and large, a long range game, so allowable aiming error is much smaller. Instability is a real problem for shooting game guns at trap. You can do it, but it takes more work than with a trap gun. As noted above, gun fit is usually way less than optimal for trap. My best efforts have involved shooting the game gun by the instinctive method; hard to do if you have developed muscle memory for trap with a trap gun.
