cayugad as far as blood trails go my father & I shot 5 deer with them , 3 never moved & 2 went 40 yards ,the blood trail on the ones that ran were not spraying by no means but they did not go far enough to start I think . 4 out of the 5 did not pass through , found slug under skin on other side . Three of them were long shots over 100 -125 yards, but when I opened them up the chest cavity was like jelly inside so the bullets did what they are supposed to do , I am wondering if they would act the same because 12 ga is 2100 fps, what kind of load would I need to get this in my 50 cal i do not have a chrono to check fps .
