Fired my first black powder cartridges and had some problems
I finally made it out to the range with my .43 Spanish rolling blocks and the ammo I made. I fired a total of 8 rounds and I noticed some had a line on the neck that I could feel with my finger nail and one case actually split open and almost went all the way around. Most of the cases had the primer pushed out a bit after firing.
I used 85grains of 2F old eysenford powder
CCI large rifle Magnum primers
I used a drop tube and compression die then seated the bullet to the crimp line with a tiny crimp.
Can anyone tell me where I went wrong ?

Sounds like an over sized chamber to me. You might try annealing the brass you have left and just neck sizing.
