Ok, i cleaned this up for a bit better assesment of the ole girl at 40yds on say a turkey head, no didn't take art..... Pic basically self explains, but that's zoomed in 40yds view, used a shooting stick , left with a,7.5 high speed dove load 12 hits head neck. Right is a favored heavy #6 (1 1/4) 13 hits. I cant say for sure I dont know but I believe both would be kill shots the 6 probably more reliable effective on such a big Bird. Soooo why cause, I like know,limitations. Also, can ya use a 100 dollar gun cheap shells instead of 3.5 inch cartlidge destroyers in a gun with a choke that cost more than my single ? Yes within limits, if ya need to bust one at 60 yd gotta spend $$ im just gonna git a lil closer myself bad shoulders.
