Other than the weight difference between the 50 cal Maxi Ball-ets and the the regular Ball-ets (270 HP/245 RN gr), how are their on game (deer) performance? Why the hollow point on the 270 gr bullet?

If I can get them to shoot well out of my GPR I might use them this fall for deer. I've shot the 245 gr with 70 gr 3f Goex and they grouped well at 25 yds. I plan to shoot both tomorrow. Does anyone have any pet loads for these two?

Thanks,
