I have a Freedom Arms .454 Casull through which I have been shooting 300gr Hornady XTP and Sierra bullets. I have never had a problem with the either bullet but I understand the "mag" XTP is recommended for full power .454 loads.
I have about 300 XTP bullets in 250gr and 300gr, so I decided to download to 45 Colt to shoot out of the .454.
I have .45 Colt RP cases, and 26gr of H110 with the 250gr XTP had 5 rounds touching each other at 25 yards (book stats = about 1100 fps). The 300gr load is 18.5gr of H110, and 5 shots fit inside a 3-inch circle but do not group as well as the 250gr.
Anyway, it should be, once the round is fired, the case expands to release the bullet. What I've found is neither .451" or .452" bullets will slide into a fired, unresized case .45 Colt case at all. If I resize the cases to deprime, and bell the mouth I can reseat both bullets without any bulge or effort.
Is this a problem I should be concerned about?
