I have used Unique powder for all my light handgun loads for years, but after this week end I think my revolvers will get a steady diet of Trail Boss for plinking loads. I loaded some 250 RNFP over 5.4 grn of TB yesterday in 45c. Accuracy was great recoil was nonexistent and no leading.
I was shooting this in a Bisley New Vaquero. I had a 2" black dot on a cardboard box for an aim point. After the first shot I thought the bullet had lodged in the barrel because of lack of recoil and I didn't see a hole in the box. I unloaded pulled the cylinder out and checked the barrel- barrel was clear. Walked over to the target and nearly dead center of the black dot was a .45 caliber hole.
Fired a total of 25 rounds of this load and had 3 - 2" groups of five and 2- 3" groups of five. Point of impact was dead on point of aim for all five groups. All groups were fired off hand from 12 yds.
I have read a lot about TB and have had 5lbs on hand for a couple of years. Glad I got around to trying it. Something I noticed, The TB I have is labeled Hodgdon but the stuff I see advertised is labeled IMR. This is the same powder I isn't it?
If this powder will do the same in my 327's, 357's, 41's and 44's I'll give up Unique in everything but shotguns. I didn't set up the chrono but data said 700fps which is plenty fast for my plinking.
