I've disected a Remington 260 Managed Recoil round or two..

they are loaded with 30 grains of IMR 4198 and a 140 grain Rem Corelokt..

If you handload and want even better accuracy.. load 30 grains of RL 7 instead..

The 120 grain Ballistic tip is still the best bullet for that lower velocity..30 grains of either powder and the 120 BTip will give you an MV of approximately 2450 to 2500 fps..
