Do you use Trailboss in your Nagant ?
I have a Tula 91/30 dated 1944, that was given to my Business Agent.
We took it to the range once, when it was his with Soviet surplus ammo, it was not pleasant to shoot.
After three rounds, I was done, it's been a wall hanger since it was handed (given) to me (along with the remaining ammo.)
I guess Dennis was done too
