I shot my Marlin 25MN today. At 100 yards I got groups around 1 inch with this Win 30 gr tipped ammo. Some later groups opened up, but I believe fatigue, failing light and smaller targets were to blame.
I also got similar groups with CCI Maxi Mag JHP and white box Win Super-X JHP.
Federal 30 gr, PMC Predator and CCI MM +V were all quite a bit worse.
