Sorry about the short intro. I was very tired.....anyway. I will list the things that have been done to my rifle. It is really just for fun, although I do plan to use it for at least a few competitions each year. Midway SS bull barrel,bore polished, hand polished sear, lightened hammer, target trigger w/stop, volquartsen stabilizer, Fajen silhouette stock, free floated barrel, various extra power or reduced power springs,24x target scope. I have my best results with Federal Match, 25+ yards sub .5" 10 shot groups. The only limiting factors I can see is MY ability. I was trying to see if I had overlooked anything in my quest for the one hole group.
