Ifin this be her maiden shoot then please do start gentle her bein' a virgin and all. I would start at 80 with that shot load and work my way up. But I betcha ya be liken it around 95 - 100 grains better. (BSEG)
Not "period" but I 'ave a friend that is "all things expert" about smokeless and 'as several champs under his belt in speed/accuraccy in the SASS world. Give 'em 'is due. He be fast. But NO BP experience. So he goes and askes all the right questions to the all the wrong people. After I found him a grand deal on a .58 Zouave. "$175 never fired) Went with him to shoot it for the first time and he's telling me how it's supposed to be loaded. 60 grains, no wad or patch, using maxies. I just sat back and said'"Realy". He couldn't hit the paper at 50ft. but did hit the target 4 over from where he was aiming. I walked down range and got the target he hit and brought it back to show him the perfect cut through of the maxie as it went through the paper sideways. No expansion "0"! "Well, why didn't it work." "Well, because you wouldn't listen to me or anybody else who's been shooting BP most of their lives but instead refered to all these SASS guys and "the internet" sites YOU like. Now! try this pre-roled .58 charge I brought. Tear the top. Pour. Shove the paper in. Drop in the maxie. Push it down. Now tap it firmly. Cap and shoot. BLAMO! hit the paper. Go figure. "Why did that work?" You didn't have enough compression to expand the Maxi to where it would catch the slight rifling this thing has and shoot straight. Not enough lead in your butt so to speak. 80 grains and a paper wad or cloth patch.
