Matt's 500 gr in 45-70

Hi,


I was always interested in these bullets but never had a starting load point.


I reached out to them and asked for starting load data but was told there are a lot of people using them, so the data is out there.


As of yet, I haven't found any.


Im not looking for high level loads.


I know Chris Costas runs a 500 gr load at 1350 ish, Im not looking for that fast, more in the 1150 ish


I was hoping to use h4198.


I was hoping someone with quick load data or actual data might have some suggestions.


Below is the data on the bullet

Thanks in advance


This bullet is 1.242 inches long and .400 from the crimp groove to the nose. It was designed to function in a lever action.



Thanks in advance

Much thanks for the reply.


I saw that load data for the 500 gr bullets but that lists it as am oal of 2.8


Matts 500 gr bullet is 2.55 to fit in a lever action.


Ive added a picture of the bullet for reference
