Improved Hoch action 22 LR. Could be used for bench or silhouette. No. 4 part octagon barrel. Built by Meacham Tool & Die to their exacting standards. This rifle is very accurate and will shoot with the bolt action 52's, 40X's and 54 match rifles. Frank deHaas wrote a good description of this action and the original Hoch in his "Potpourri of Single Shot Rifles and Actions" Will e-mail a copy if interested.
