Thanks! I picked up another Krag in need of some work, and while I could part it together enough to get a reasonable facsimile of a carbine, it was definitely going to need to be re-crowned in order to have any hope of decent accuracy.
Been messing some with powder-coated bullets, and have had some success with one of my rifles. Wasn't sure if a load like that was acceptable (assuming decent groups are possible below the velocity cut off).
