I don’t have the same experience as some of the others here but I have shot monos for deer and one moose in 300 win 257 weatherby and 243. In my experience if you hit them in the lungs with no major bones they typically don’t go down right away but with the ttsx I don’t think I have had anything travel over 30 yards. I had one doe shot through the lungs with a 100 gr tsx out of my 257. Showed no real signs of being hit and ran about 70 yards and was dead. Anytime I hit any major bones or neck shots nothing has travelled far at all and most dropped on the spot. I agree that on average the cup and core bullets put animals down faster but if you put a mono in the vitals and especially if you want to save as much meat as possible I have no issues using the Barnes bulletsYes, sorry I wasn't more specific about this: I've killed them with everything from a 22LR to a 375 H&H and all the different types of bullets. I know those 22s work because I've used them on hogs, and still do on occasion. But I normally don't have the time to cut these pigs open, and I'm probably not smart enough to know what I'd be looking at anyways. All that to say, I understand the differences between a fragmenting lead core and an expanding mono within the same caliber, but not within different calibers. I'm curious to know the wound channel differences between a .308 130 TTSX and a .224 77 tmk at the higher velocities.
