Just bought a 300 RUM in Rem 700 BBL.
Plans are to shoot 220 SMK long range and 200 AB for hunting. Found a lot
of load data on the 200 AB and just a little on the 220 SMK bullet for
shooting long range.
Many shooters shoot the 220 SMK at all?
After barrel is gone I am building a 338 EDGE on the action but for now look
forward to shooting the 300.
3.75" OAL, 91grs of h-1000, fed 215m primers, rem brass, runs about 2900fps out of my stock remmy. Shoots under MOA always with some .5 moa groups.
Good luck working it up, Start at lower powder weights and move up.
