RE: wolverine
The USAK American Knight for $90 is an absolute STEAL!!!!!! The only difference between it and the Wolverine is the trigger. Otherwise it's the same action & same Barrel (22").
Again I would add my voice to HIGHLY advice the .50cal over the .45cal. Load workup will be a 100X faster process, since there are SO many more bullet/pwder combinations available for the .50cal.
