Yup, assuming you are not interfering with free recoil of the barrels, a little more speed is needed to stop the crossing in these. It might raise the impact up a bit. Looks like the Euoplia is still regulated for the "right load". When you get 4-6" groups at 100, you know that you have the right load - wad, hull, ball alloy, ball diameter, powder, etc. tons of variables to play with & can be frustrating.

Very nice B & S.
