ok i'm still new but i'm realy learnin alot from you guys so what i have is a trad pusuist lt. 50cal, now my question is when i get to the range to sight it in and work up a load how do i know if as you guys put it if the gun likes what i'm using? i bought some bh. and hornaday xtp .452 45 cal in 300gr. and harvester black crush ribbed sabots. now i know when i shoot my cartridge rifles its just buy a few different boxes and what groups best go with em. but on this i read that some group good and then go bad with higher volumes of powder and vise versa. so how will i know if the gun dont like the setup or if i need to go hotter charge if its just shooter error? i am thinking of starting out at 80gr. of bh to start or do you guys recomend something else? and i havent got the primers yet i bought the wrong ones so i need to get more what do you recomend.
