I find that W296/H110 perform the best using the 44mag, using jacketed bullets. Seems lilgun likes bigger heavy bullets, more suitable for the 454 Casull, I have found some strange power spikes with LilGun in my 454 Casull, found a sweet spot, then only one grain hike,still below max load, I could feel the higher pressure and recoil, too touchy for my likes, I like a powder that has a slow to moderate upswing to power, easy to find a good load, not erratic. Just my findings. Only tried it in two types of bullets Hornadys 300gr XTP .452 and Speers 300gr GDHP's .452... Aim small hit small. RAMbo.
P.S. I forgot to mention what caught my eye's using lilgun was the big decrease in CUP comparing to the other book loads using w296/h110, in tern less pressure lower recoil and less beating up on the revolver. Good cocept if it works.
