Found Ballistic Calculator for Spheres, #6 is good.

If federal every ditches their flitecontrol wad and loads up a 2 1/4 load of their heavyweights it would awesome. I wish they would load a trial run and send it to Clark for testing in a 3" 2 oz load. I am still kicking myself for not buyin more than 2 cases of their waterfowl loads before they quit selling them as #4s completely blow through geese and break wings at 50 Yds.

I could only imagine the results of a 5,6,7 or straight loads of 6,7 's i!!!! Pellet count would be about 34% less than lead but the way everyone talks about the 7's @ 1100 in a 20 gauge would make me have to shoot them.

Very interesting..this science proves what allot of turkey hunters have found to be true through experience. Whether you are shooting Pb 6's, Hevi 6's or 7's, producing dense consistent patterns to 40yds, keep your shots inside 40, and the lethality is much more efficient. Pb 4's, 5's, Magblends, TSS provides more distance if the patterns will hold up. Trouble with pushing distance is all the factors that are present in the turkey woods. Thanks for sharing that chart with us.
