Of the four custom big bore round ball longrifles I've been fortunate to have had time to test out , three were Pa. deer hunting rifles ,and one ,a .50 , was a deer rifle and a competition rifle . All four rifles had one "sweet spot" load for all occasions. I just wasn't one to switch loads around for different occasions. To each his own. .................Now there is this ugly skinny 3/4 st. oct . brl , .40 cal , patterned after an old relic from the Cheat River Valley of Preston Co. W. Va. that has captured my attention . This rifle likes 35 gr. fffg for a light load , and 50 gr. , fffg for a more robust job. Here in the Pa. big woods , there are mountain lions , 700+ lb. black bears , red wolves, coyotes, and sundry other creatures to defend against , while taking a walk in nature. Bearing that in mind, the 50 gr. load is my go to load. Good shooting to ya.........oldwood
