I thought you had the Deerstalker. I almost purchased one of them. They really looked like a nice rifle to carry around. And you have shown they are good shooters. I never tried cotton duck, but I wonder if them old carhart duck cloth pants in my closet would work? Although as worn as they are they are no where near .023 anymore. I just wore them out. Wood cutting will take a good pair of pants and kill them.
That is great shooting. It makes me want to shoot more and more. I am wondering if I need a larger bulls eye at longer distances so I could focus on say the sights cutting the middle of it. Them little 2 and 3 inch bulls I use look awful small to me way out there.
I do know one person, he swears to it, and he said he shot a deer with a Lyman Great Plains rifle at 134 steps with a roundball and the buckhorn sights. In fact he said after he shot he was kind of upset with himself for even shooting. But it was in the middle of a hay field and he had a good rest. He said it ran about thirty yards and just tipped over.
I have seen how well Semisane shoots that Lyman Great Plains Rifle of his. One reason I wanted one so bad. I think I will be shooting that with olive oil and liquid wrench next week and see what happens. Although I have to drift the sight a little still.
