Does anyone here know what is largest cast bullet, LBT style, that will reliably feed from the Ruger 44 Carbine or Deerfield? I realize that the guns are gas operated and the lead bullets can cause trouble, but they would be gas checked to alleviate this problem. The main thing I'm looking to find out is the max OAL allowable with these rifles and if they will reliably feed the LBT bullet styles.
