Lots of good things to say about the Krag and only a few bad. The only real bad is that they are definitely not suitable for high pressure loads. For those of us whose eyes have started to get old, the sights can be a little squinty, too, but there is a very slick receiver sight (Redfield, I think?) that mounted without need to drill and tap the receiver. I have one in the "sights" box, but haven't gotten around to trying it (note to self for warmer weather: put this on the list).
The good...lots to mention. The smoothest bolt ever delivered by the hands of man. Beautifully made, literally old-world craftsmanship. Nothing made after the start of WW1 really is on this level. Soft-shooting. Excellent performance on game, if you want to hunt with this cartridge. When you get used to the magazine, it's pretty slick, especially relative to other rimmed cartridge case repeaters - you don't have to worry about correctly staggering case rims. I could go on...take it out and enjoy it. The old 220 grain round nose load which was original issue with these rifles shoots particularly well.
