I have L.C. Smith 16 ga. from hammer gun to Specialty Grade and like them all. Really fond of the hammer gun/s.
Since all of my 16's are 2 9/16" chamber, I roll crimp them using either the one in the drill press or the old fashioned hand crank one. Frankly, the hand crank one is faster.
A friend found a recipe using RST 16's, 2 1/2" hulls using the same wad I use for roll crimping, Ballistics Products SP16 and fold crimping them. Might have to try that.

If you join the 16 ga. Society and 16 ga. Reloaders site for a one time fee of $40.00, there are more 16 ga loads than you could ever shoot.
