I have the 444 with the 1:20 twist and 22 inch barrel. I have only shot factory loads at this point, but I really like the gun. I have never owned a 45-70, but I am sure they are a great gun also. I have just got set to reload, I bought H4895 and the hornady 265gr. I also plan to try some cast around the 300 gr level. I replaced the sights with the williams peep and the front fire sight.
