MOST Savage MLIIs run on the loose side. Mine did not but it still would not shoot the EZ load sabots or the crushribs as well as a tighter sabot.

If you have some 50cal bullets like the 50/300gr FTX its easy to tell. If the 50cal FTX will drop down your bore its a looser model. The 50/300gr FTX runs really close to .501. They would not start in mine.

I could shoot the MMP short in mine with a 250gr but they were a bear to load. Mine liked loaded sabots in the .505-507 range the best. Anything under .504 would not shoot very well with a couple exceptions. The Harvester smooth black for under 300gr bullets would sometimes shoot ok WITH a .452 300gr bullet.
