Are the chambers in your barrel smooth? Are you having problems with casing stickage in the chamber? Having problems with extraction? Steel casings do not shrink instantly after firing as much as brass cased ammo. Romanian 8mm has an excellent reputation as far as surplus goes. I used it exclusively in my MG-42 for years.

What size nozzle are you running. You could try a slightly smaller nozzle to increase the recoil pulse. Try that and see if it helps.
