Have a new Ruger Bisley Vaquero in 44 mag, bought some ultramax ammo, 240 gr lead, cowboy load to try. Had a real problem with leading right after the forcing cone, at the start of the rifling. So much that with 100 rds, the grooves were filled to the point of equaling the height of the lands. What could be causing this with factory ammo? Accuracy went down the tubes also. Yet after being cleaned, shot some full power JHP loads and POI was POA and accuracy was fairly good, ie 3" @ 25 yds. Some of that was me. Cant really see any signs of shaving lead, Would this be a case of too soft or too hard lead?<!--emo&???--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'><!--endemo--> Never had this problem before.
