The 325-grain FTX .458-inch bullet that is available for reloading has two cannelures. Does either cannelure permit reloading 45-70 ammunition when using brass trimmed to 2.10 inches and 2.55 inches overall length?

Yeah - that's what the deep seat cannelure is for. Hornady sells 45-70 ammo using that bullet.

I'm not certain you responded to my question. Hornady's factory-loaded 325-grain FTX cartridges use a shorter-than-standard 45-70 case. This is what I want to avoid if it can be done.

No, you will have to trim the case back to the specs Hornady recommends.

This is so you can crimp and still have the proper OAL.

i wonder how fast i can make them go in the 458AR
