Loading .223 on the LNL using the Hornady powder measure and CFE223 powder. The powder meters nicely - but - the pistol rotor is of course too small to get a full drop and the rifle rotor is touchy. The rotor stems are threaded at 1/2 x 20 tpi. On the pistol rotor you get about 1 grain powder for every turn of the stem. On the rifle rotor its more like 5 or 6 grains - so .1's are difficult to dial in.
I took a pistol rotor which has a powder chamber that is 0.315" in diameter, and bored out the powder chamber to 0.4375" diameter (7/16 ) This approximately doubles the powder capacity of the rotor. I made a new stem for the rotor - I think you could turn down the plunger end of a rifle rotor if you so desired - but I just made a new stem.
I haven't had a chance to try it yet - but it threads in and out nicely without jamming on the bore. I'll give it a try here in a bit and see how it is to dial in.
