Yes I understand this and shoot to save meat.
Example 6 deer all shot the same double lung shots.
3 with 270 and 140 bthp and all ran 25-50 yards.
3 with 243 and 58 v-max and all hit the dirt like they was stuck by lightning.
I have said this over and over and I just had to prove it to myself one more time because people keep saying you can't kill deer with a 243.
Rather it's a 243 or 270 or ?? I have always had better results with a lite bullet
and a double lung shot and the bullet never comes out the other side and the deer took everthing that bullet energy had to give the heavy pass on through bullets
do not stop and the deer only takes part of the energy.
Its not the energy that is doing the "killing" for you there. Its the bullet fragments your sending several FEET thru that deer!! Talk about loosing meat, you must have horrific holes and blood shot meat from that varmint bullet!!
Ultra lite varmint bullets can produce this kind of ''THORS HAMMER" effect. Trouble is if that animal moves or your aim is off and you hit that shoulder or need to penetrate thru a couple more inches of hide and mussel. Your soon see the south end of a north bound animal!! Oh you will likely kill the critter, but I doubt you will get to enjoy the spoils as you will be feeding the carnivores in the area!! Using the 58Gr bullet for big game is not a responsible thing to do. Heck the standard Varmint weight for the 243 is 70 Gr's for Pete's sake!!
At 300 lbs your at about as big as I feel comfortable with the 243. But the 270 is just fine. Even that 243 with good bullets and a carefully aimed shot from a patient hunter will not have a problem. An animal traveling 50 yards after a lung shot is PERFECTLY Norman performance. Try hitting bones, like high shoulder or if close enough, the base of the neck, with that 270 load. Do that right and you will see the same Bang Flop you experienced with those varmint 243 bullets!
