Mowrey made some fine rifles. I was shooting competition in the late 70's at Electra, TX and Brady, TX with the Red River Renegades Black Powder club and Mowery would show up with some rifles. I shot a few of them and one that sticks in my mind is a 54 cal, with peeps that we would shoot off of cross sticks for a Buffalo match. That rifle with the 1-60 twist was remarkable. It liked a little more powder that my shoulder did when getting the best groups.
There were a lot of his rifles for sale about that time because most would purchase them, mainly in smaller calibers and it would be too
heavy for them shooting all day. Like most, I was without funds then just getting a new job and shooting a Dixie flint Kit in .50 that was given given to me if I could shoot it and would take care of it. I really wanted one of the TX built later models in iron hardware in a .54.
Some guys around there had installed new barrels in .62 and .58 for Elk and other big game by Mowrey or themselves.
Thanks for the PDF file. Had a couple of articles from NMLRA magazines back in the day that I have kept.
Nice find on the kit.
