Ok, good to hear that. I cast the bullets from scrap lead collected from indoors airgun range.
Bullets sized 11.41mm are snug fit to my barrel.

Went testing today. 500gr bullets grouped to approx. 20cm, but holes were not round. So they didn´t stabilize properly.
Tried with ca. 45gr load of Swiss #2. Recoil was a bit unpleasant even with that load... Also forgot the wads home. Will redo next week.
