Chambered in 7mm Altius (54r Improved necked down to 7mm)
27" Hart barrel
Athlon Argos scope.
54r Bond Improved vs .308 WIN:
After I made the print, just for fun and out of curiosity, me and my brother machined a facsimile from an old bolt.
So this gave some real visual aid to the endeavor. The machined bolt on the left. And stock 54r case on right.
