Gentlemen; I have a factory #1 in 38-55. 500 were made in the late '70s for the Cast Bullet Shooters Assoc. Wonderful fun gun but i have a problem. Ruger confirms that they made the bores .379( mine slugs .3798 as best as I can measure) at the request of the buyers. <!--emo&???--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'><!--endemo--> Any suggestions for cast .400 bullets? My .377 Lyman and Saeco moulds sure won't work and .375 jacketed start tumbling in the bore!
