I made 180gr LRN max loaded with h110. I'd shoot them into the ends of blocks of firewood 16 to 18 inch. I also did this with 240gr LSWC 44 mags and 300gr LWFNGC loaded as hot as I could. Both in 12in carbine barrels.
For what it was worth I recovered almost all of the 44 cal bullets. 300 deeper than the 240. I had a hard time recovering the 180 LRN. They would over penetrate the 44 and usually completely through the blocks.
All that I learned in this case was the 180RN to penetrate deeper than a 300WFN. Just thought Id share.
I still prefer the bigger hole.
