You’re still not getting what he’s saying. The observation he stated is exactly why I have pounds of titegroup leftover from a purchase ten years ago. When I shoot, I burn about 300+ rounds in a range trip. I work the cylinder exactly as he describes. Any powder will get the cylinder hot. Titegroup seems to get them much hotter, much faster given a similar rate of fire. I actually got to the point, more than once, I couldn’t touch the cylinder at all. I can’t recall that happening with another propellant in similar circumstances. Now all that said, Titegroup meters like water and makes accurate loads. I will get around to finishing the stock I have on hand.
