Looking at the Hornady page, I only find a 325 red tipped .458 diameter bullet in FTX.

XTP is only in handgun catagory and is pretty much a hollow point self defense bullet.
I saw your other thread about 45-70 loads last night.
I load 325 gr cast hollow point bullets and have loaded other soft point bullets too.
At 150 yds and under, I suggest you sight in at 100 yds and find what the drop will be at 150 yds.
Any of these 45-70 bullets will kill a whitetail.
I have loaded with Unique and Trail Boss with cast bullets and with Benchmark & Varget in the jacketed soft point and Hornady FTX. There are better powders to use, I am sure. This is a 45-70, it will kill any large game in the US.
I have Hornady dies, It's a three die set. Sizing, Flaring, and seating/crimp. The Hornady shell holder probably is too thick to insert in a Lee press.
The crimp is set with the seating die adjustment but I wouldn't be surprised to find a factory crimp die is available.
Yes, I lube my cases. No big deal. Don't try
NOT lubing them, they'll get stuck.
This was one of my early loading experiences.
I loaded the FTX or leverevolution bullet myself.
I am pretty sure they are one in the same in this case.
I have a Marlin 1895 guide gun. The Trail Boss I loaded up for an antique trapdoor my buddy has.
I shot some and found they are nice for my guide gun too for a more relaxing session. I wouldn't choose these for deer but then I wouldn't want to be a deer and get hit with the Unique loads.
