hello, i like roundballs also, and used them here in pa. back from 1968 to around 1980. shot a lot of bucks in that time with them . do i like them now for deer, yes, but dont use them. i feel i get better groups at lower powder with the maxi-ball or powerbelts for DEER. most roundballs you should shoot a higher powder charge to get velocity etc. my best groups with roundball were 75 grs of 2f but hunting i used 100 grs and groups were not good but more power to send roundball to deer. i did not like kick also.look at roundball,i think he shoots 90 grs of 3f with his round balls on deer, thats around 105 for me on 2f.wow, what a kicking machine, not me anymore. i like shooting like i am holding a .22 cal, ha. also the maxi/powerbelts are much easy to load at 10 above zero here in pa. i broke a few rods hunting using roundballs in pa. in winters of 1970s,brrrrrrr, it was cold then, nothing like now. its just so much better with the maxi/powerbelts to reload than the roundball in cold. i could never get groups with roundball as i get with maxi/powerbelt. roundball does, he gets good groups but he shoots aLOT, more than average person.he has everything down to nuts/bolts. most cant shoot like that and refine their shooting and loads etc. so, MAXI-BALL/ POWERBELTS will fill in that void that helps the shooter that only shoots a couple of times a year and hunts that way. for practice i amd shooting nothing but the roundbal BUT when i go hunting WHITETAIL DEER,IT WILL BE the maxi-ball370 or powerbelt 295 in .50cal with 1-48 twist flintlock with open sights. my favorite load is 80grs of 2f with the maxi-ball or powerbelt and around 75/80 grs. of 2f for .490 roundball. roundball is real good at ROUNDBALLS and cayugag too. both shot more than me with them as i could never get real good accuraty with them with my twist of 1-48, they do. its little tricks to get a roundball to shoot well and they both know them. take care.
