Yesterday I took "Big Ollie", my 50 caliber round ball chunk gun to the range to get scope settings for shooting out to 40 rods. Since we have even distances such as 100 - 200 - 300 yards I went out to 200 yards. It was shooting 10 shots inside a 3 inch circle at 100 yards so out we go. I used the same load I.E. 80 grains Goex FFG, .490 pure lead balls, pillow ticking bought at Walmart lubed with spit and #11 caps. I checked my range book to see what I had used for the 540 grain Creedmoor bullets so I upped the scope settings to match those since both are Unertl scopes.
I asked a shooter next to me to look at the impact incase there were no hits on the pain white backer. He said the hit was below the backer in the dirt so up another 30 clicks. Next shot was just on the backer so up another 30 clicks and right below the 8.5 x 11 home made "shoot-n-see" exploding target. Another 15 and just below the little white center mark. Shot several more and the impacts were within several inches of each other! I checked the hash marks and they were way higher than the slug gun which I sort of expected and proved to be true. Next time I plan to try some different powder loads and also some .495 round balls. The barrel is a 1 in 48 twist Douglas XX stainless steel muzzle loader with false muzzle and the only draw back is the gun is heavy!
