Last year I picked up an 1870 Husqvarna Rolling Block and finally got some CH4D dies for reloading last month. Problem? I'm having a bit of a time trying to figure out loads for this rifle.

It seems a lot of people use 30-40 Kragicon data as a starting point for 8x58mmRD loads but few of my manuals and online sources agree with each other about min/max loads. I have one manual whose minimum load is past another's max load!

So I come to you with the hopes that someone has figured this out already. I'm currently using 220 grain 8mm bullets in repurposed 8x56mm Mannlicher–Schönauer brass (much cheaper than the 8x58mmRD brass that Bertram sells). I'll be testing new loads ranging from 39.5 to 43.5 grains of H4831SC to see how that performs but if someone has a better suggestion(s) I am all ears.
