Roll crimp
Depending on orientation of the "sprue" on the Round Balls, you may have to omit the Wool Felt for a more proper roll crimp.
I do not know this for a fact, as I have not done any pressure testing to prove otherwise, but I have had a lot of guys say that the 3" Fiocchi hull has the same internal capacity as that of the 3" Activ hull's, and that load data is interchangeable. Again, I have NOT pressure tested any loads in the 3" Fiocchi hull's, so I do not know if this is valid or not.
As far as the accuracy of this double .690 Round Ball load goes, both balls will generally stay within 3" or less of each other at 50 yards, and within 5" or less of each other at 100 yards.
One ball is generally right on target, and the other is just a couple of inches away.
For guys that use this load for hogs, I have never seen any other load that will drop a hog faster than what this load will!
Center punch the front shoulder of a deer, and it's light's out in very short order!
