Good report Dave. I'm impressed with the 250 gr shockwaves. I think that is what I'd use.
How do you keep track of your loads for each rifle? It used to be easy - but now with so many ML, I find I have to keep a log of which on shoots what the best.
Even with a log, I keep trying new bullets, powder, charges, etc. Hopefully this week I am going to try some sabot/bullets in one of the .50 LRH barrels. I got some Harvester EZ load sabots 50/44 and going to try some 240 gr and 265 gr bullets I have. Report will follow.
