Finally got to test ammo. Results: used IMR 4350, H 4350 powders 40.0 grs., Hornady 220 gr. RN Interlock .308(#3090) bullets, Remington 9 1/2 primers, with 3.000 c.o.a.l., and case trim length 2.304. Both powders produced nearly identical   1 and a 1/4"x 1/2" groups at 100 yards (5mph quartering wind) Both groups were spread right to left not up and down, indicating shooter error, not ammo spread. The H 4350 group had 3 shots grouped 3/8" x 3/8", the IMR 4350 had 3 shots touching spaced  3/16". It appears that both powders will give nearly equal results with the Krag, much different than my 6.5x55 Swedish Mauser, which does not like IMR 4350. I could not post pictures of my groups, tried to download cell phone pic from computer, and tried to scan, download groups, but got pics too large error when I attached the to thread.

Nice groups in all of Frank's posts.

As for posting pictures...I had to figure out how to resize mine before I could post them here.  After fiddling around a bit I found you can resize from Windows by right clicking on the picture while viewing it from your Documents/Pictures folder which brings up a menu including "Resize". Clicking that gives you options for Small, Medium, Large and Custom.  Tried Small and it worked fine.  It asks if you want you to save and automatically saves a copy so doesn't alter the original.  Was easier to do than describe it !
