does porting affect hunting velocity??

Jim,

Let me guess on this one. The ported choke was on the top barrel and the unported choke was on the bottom barrel.

I could be wrong, but I am willing to guess that is how you had it set up.

The reason for my guessing that way is because the top barrel on an o/u always has more recoil than the bottom barrel, even if you use the same chokes. Clay shooters will always shoot the bottom barrel first, and if only shooting a single shot, will always use the bottom barrel.

The reason for the increased recoil out of the top barrel is because the barrel is more out of line with your shoulder. In essence, the bottom barrel pushes the gun directly back into the shooter's shoulder but the top barrel tends to rotate the gun up into the shooter's face.

The results would only be magnified by a hot turkey load out of an o/u which provides no recoil help like an auto.

Let me know if my guess is correct.
