I built the KY rifle a bit over a month ago and I am really impressed with how it shoots. It is my 3rd Kentuck and the second one I have built from a kit. I have tried all the Pyrodex styles and the rifle does not like any of them. It almost likes Select but I have to scrub the bore between shots and then use a spit patch, not a lubed patch if I want any kind of accuracy. I got some Schuetzen 3f Black Powder and I think it is very good. Much better than any Pyrodex load. But it is still not totally uniform. It has its moments but there is always a flyer. This blackpowder is finicky. I have to swab the bore and make sure the bore is dry, and then use a spit patch. No big. Saves money on Bore Butter. It is somewhat more accurate than the other powders but I am not satisfied yet. I got a couple of the Mag Spark nipples on Gun Brokers and after more than 4 weeks I finally got the nipples replaced and headed for the range. Shooting at 25 and 50 yards I am hitting a 2" bullseye consistently. Next trip to the range I have to take a file to whittle down the front sight. I am 2" low at 25 AND 50 yards but all shots are on the lower border of the bullseye. Oh, I switched powders too. The Mag Spark nipples are designed for Blackhorn 209. I recommend this combination for sidelocks. I am also going to try it in my other guns. If I can bring the balls up 2" @50 yards I will be satisfied. I fired all five shots in this group and started with a clean bore. I did not dry or wet swab between shots. The group slants from left to right but it did not progress exactly that way. The shots actually started at appx. 6:00. Second shot is far left of the string. The last shot is second to last and I don't remember which was shot 3 and 4. But all broke the border of the bull. I think a light swab job between shots will tighten the groups. Hopefully Blackhorn will help me with some better shots with the Wolf and the Kodiak Magnum. Deer season is coming up in October. Whichever smokepole shoots best will be my deer rifle. And I got 2 tags this year. Wish me luck. PS In the second target, the #1 shot was a first shot test to show me where the first one will go with that load. It is the Schuetzen 3f load. 4 of the shots in the upper group...(5 shots, with one hi flyer) are wet swabbed between shots and a spit patch used. The topmost shot is a flyer, fired after only a quick dry swab. But all are acceptable for deer hunting. Appx. 2+ MOA group at 50 yards...4" at 100 yards...all good enuff fer deer. I really like this Kentucky.
