As you have 2X the experience I have ...... what caliber for Chrony?
A Berry's 230gr plated RN @ 850 did not give complete penetration......
1st one, 45acp 140 gr Glaser Safety Slug @ 1350 from a G21. It penetrated the brain and bent the middle divider WAY over but did not penetrate. I recovered most of the shot, tip, and jacket from inside the Chrony.
2nd one, a 22lr Stinger @ ~1000 fps from a FA Mini-Revo 1-18" bbl. Penetrated the brain and dented the divider. Bullet unrecovered.
