Hello, my brother in law got a cva buckhorn for christmas, and wanted me to help him get it sighted in, because I am the only one he knows who shoots muzzleloaders. He got powerbelt bullets 245 grains with thespire tip. I thinks that is what its called. He has pyrodex pellets 30 grain pellets. and 209 primers. I was wondering what would be the best load to start with 60 or 90 or 120? I have never used pellets. Also will those bullets work good with that gun? stacking that may 30 grain pellets in a row will that hurt anything? should he go get 50 grain pellets? Just give me all the info about this gun and setup as possible. I'm not use to cva's. I have always shot t/c, and knights. Thanks alot
