I shoot a inline NEF Huntsman 50 cal. 24 inch barrel, 1 n 28 twist. Going on my 1st CO elk hunt. I need help narrowing my bullets down to a few to test shoot. I bought some Maxi-balls & Great Plains to test out. But I have gotten some bad reviewed by people who said they got no blood trails & lost elk. How @ the new Hornady FPB ?
