What do you guys feel is the best calibre currently on the market and will do the most damage to a 600 lb deer inside 1500 yards ? Looking for huge wound channel and heaps of energy on target and wants to weigh no more than low 20 lbs. I am looking to see if there is a round out there that will show big bullet performance in the 1000-1500 yard range than will leave heaps of clues on the ground at impact, blood, tissue etc... Hav seen what the BMG 750 Amax will do and looking at a middle ground between this and the EDGE. 375/408 might be it ? Open to ideas and have wondered if a larger bullet diameter than 375 Ct may do better ? straight 408 or 416 ? Not sure either way yet. Throw your 2 cents in please !
