Has anyone tried any of the graphite barrels (e.g., Butler Creek) on a Ruger 10/22?<br><br>I have the standard factory barrel on my Ruger Deluxe Sporter (vintage 1984). I typically get about 1 1/2" groups for 5 shots at 50 yards. I'd like to improve the accuracy without greatly increasing the weight. It is primarily a hunting gun.<br><br>Thanks,<br><br>John
