Lee Loader

Any body here playing with this - super sonic? What weight bullets are you using? Powders?

Make smoke,

I loaded some but sold my upper before I shot it. Then I built another and did the same. Then I built one for a friend. Not sure if I loaded any for him either. To be honest I think I was just about equal to .357 Magnum loads...powder and bullet weight for supers in 300BO.

I built one. I am processing 1,000 223 cases into 300 AAC Blackout. I was about half finished when I went into the hospital. I did make and fire one round with a Lee C309-17-f. My load data is back down at my barn, but the round was not subsonic and fed well from the mag to the chamber. If it doesn't rain today, I will go get my load data and post it here.

With my 10"Ballistic Advantage barrel.
Hornady 125gr FMJ 30196, with H110, (which is supposed to be the same as W296), works good, no problem cycling or bolt lock back. I liked the H110 better than A1680 at this bullet weight.
Everglades V2 147gr FMJBT and Lil Gun, also woks good, cycles and locks back. Again, I liked the Lil Gun better than the A1680 at this weight.
A1680 worked good with the Berry's 220gr Plated Spire Point, subsonic.
I have some 110gr, and 150gr Supers loaded up, but still waiting for enough snow to melt to test.
