Re: powder choice
Yet another vote for Blackhorn 209, nothing else equals it. I can take the T/C to the range without cleaning equipment finally! Took 14 shots a few weeks ago because I had a new Leupold 2-7 to sight in and there was no loss of accuracy at 50 and 100 yards. Very little difference in loading effort from completely clean barrel all the way to the 14th shot. Stable shelf life too. Just remember the maximum load by volume that should be used is 120 grains, not 150 grains like other BP substitutes.
