I have a Marlin 25mn rifle (1972) when shooting win. 34gr jhp my groups were 1/2" at 50 yds. Then I tried Rem. 33gr. jhp at same range and now get 3/8". The gun sure loves that ammo. I ended up buying a brick of ammo so i'll have plenty to hunt with. I like to head shoot rabbits, squirrel, yotes, and pats. I'll be passing down the rifle to grandkids when the time comes. Well happy shooting to all.
