For those who own a 44 caliber USFA, have you slugged the barrel? If so, what did it measure? Also, the chambers. I'm talking about 44wcf, 44sp, & dual cylinder models. From articles I've seen online, in years past, USFA used a .427 barrel for their 44-40s. That apparently hasn't been the case the last few years. I was told, by one person, 44-40s were changed to .428 several years ago. Another said .429 is used on all 44 caliber USFA guns sold today. Conflicting info given to me by two different individuals. Both in a position to know. So, I'm wondering what you guys have discovered.
Even if you haven't checked the barrel or chambers, I'd be curious to know when your USFA 44-40 was made and how it performs. Any accuracy or leading issues?
Thanks
