It's really a matter of playing with different loads until you find the one that works best for you and your particular Krag.

Thanks, I figured as much, but thought the asking might winnow the field a bit.

My .30 Krag rolling block is now disassembled in preparation for a trip to a gunsmith. I'll start with the common 168 gr spitzers when it returns. The 100 yd range was closed the day I tried my first 220 RN loads, but the 50 yd results are promising.
