I would like to try swiss but I think the price is a little out of hand $17.00 a pound .I here that swiss is the cleanest burn from all the powders
Swiss is my favorite powder. It does burn much cleaner than Goex and gives more velocity, too. I don't know how much more, because I don't have a chronograph, but I have reduced my hunting loads, using Swiss, by about 15% from what I used with Goex and seem to have comparable velocity. My rifles are also more accurate with Swiss. However, like you said, the price is hard to swallow.
After reading some good reports on Kik powder I purchased some to try. I really like it. Jerry, at Powder, Inc., referred to it as the poor man's Swiss because it gives comparable velocity and also burns quite cleanly. After using some, I would agree with that. Velocity seems to be equal to Swiss and it burns almost as cleanly, cleaner than Goex. Accuracy of the loads I have used so far, in my rifles, is outstanding. At about $210 a case, delivered to my door, it is the best buy in there is in blackpowder, IMO.
