i finally got my sporterized 30-40 krag out and i shot some loads. pictures look like c$#p, but your dealing with a stroke-abled guy who can not seem to draw with his left hand!!! i've been using a scope now for 20+ years, it was a little odd for me to start using open sights. i have, thank the Lord, 20/15 in the left eye and 20/20 in the right. i don't know HOW they did/do it(young and full of pep in the 1900s), but for this guy its going to be a redfield 102k (that i bought) peep sight.

everything was shot at 50 yards.

165gr(173gr) ranch dog(.311") with 25.5gr of h4198

i took 20 rounds out because i had to sight it in. rounds 1 and 2 shot the bottom of the paper. 3 was real high. 4 as you can see was up a little bit. 5 and 6 were low and to the right. 7 and 8 are a little high and left. 9 and 10 almost there, but high and left. 11 and 12(i don't know what i was doing?) low. 13 and 14 a little to the right. 15, 16 -17 are almost on.
the first 3, i had my sights way to high, i think 500yards, and them boolits just kept goin!!! alright, they didn't. they stuck in the dirt bank past the target. i couldn't believe how good the ranch dogs were. i've got a couple of more powders, but i think i'm going to stay with h4198.

Great shooting!  Your results speak for themselves.  Even the 190s aren't too bad.  Any of those shots would mean a dead deer in anyone's book! 

The 165s seem to be pretty accurate to me.  I've shot 165 gr Hornady BTSP bullets in my last 200 yard CMP match with fairly good results.
