Because you are shooting a rifle, and your priority is playing, I recommend a 280 gr LFN. It can be shot at low velocities, and is a quick varmint killer even with mild loads and feeds smooth as silk. Best speed for playing, in my opinion is 1200 fps at the bottom, with 1400 fps making it a deadly thing with fairly flat trajectory. If you like playing with a bit more snap, crank it up to 1600 or 1800, but you might get a bit too much kick out of shooting it at the upper velocities. Top end velocity will be around 1900 fps. and recoil will have most shooters undevided attention.
For other readers who might be interested in the heaviest weight practical,, a 300 gr is max accurate weight, and top velocity a bit over 1800 fps and it needs to be moving at around that speed to stabilize at long range. My testing being at 450 yards.
