I loaded up 50+ 30-40 Krag rounds a couple months ago. I got side tracked shootin my handguns, and neglected doing the testing with the Krag rounds. So, a couple days ago I decided it was time to get on with it. The boolit
used, was the Lyman 311284. Cartridge overall length is 3.060. Powders used were IMR 4227, IMR 4198, and Re-7. My rifle has the Redfield receiver sight. Distance was 50 yards. Target was a 8" black, with a 4" white
bullseye. Results were, I thought, very good considering my aged eyes.
#1. 7 shots: Re-7 18 grains. 1.3" ctc.
#2. 8 shots: Re-7 19 grains. 6 shots .770 ctc
2 shots pulled out to 2".
#3. 7 shots: IMR 4227 17 grains. 1.23" ctc
#4. 7 shots: IMR 4227 18 grains. 1.15 ctc
#5. 7 shots: IMR 4227 19 grains. 6 shots 1"
1 pulled out to 1.375" ctc
#6. 10 shots: IMR 4198 19 grains. 9 shots
.735 ctc 1 shot out to 1.12"
#7 8 shots: IMR 4198 20 grains. 7 shots
.900 ctc 1 shot out to 1.23"
As you can see, it's going to be hard to pick out which loads shoots the best. My plan is to load some more rounds, and move the targets back to 100 yards. I realize how much I took my good eyesight for granted in my younger days. With sights and targets going blurry from time to time, and all those darn floaters floating around its a real drag. Going to hit the range in the next few days. After the 100 yard testing, I'm going to jump to the 200 yard. That's the longest distance at our club.
I'm really enjoying this 120 year old piece of art. Good groups can put a smile on your face.
Good shooting to all.
