Made a quick run to the range. I tried 40 gr volume of 777, shot well, less smoke than black and no stink. 9.2 gr Trail Boss, also grouped well but no smoke...weird! And I tried the 50 gr pyrodex tabs, they worked well and had some real steam to them. Now I've got to bang that miserable sight over to the left a ways. I'll have to stick my clock on these come spring. I ran the Trail Boss last so clean up was a breeze. The pyrodex were a tad longer than the rest (1.65 vs 1.62) but fed well with a two step action, lever up until it bound up slightly, release pressue then take it the rest of the way in. No indication of pressure with any of the loads. Trail Boss is pretty neat stuff, fills the case almost to the base of the bullet.
