My dad shot a bull one year at about this same angle. Shot once through top of 5 and the bull just hunched up. I called a wind correction and he put the next through 1. The bullet went through the back of the close side shoulder blade, through two ribs then exited. Was a 130 berger hunting vld at 685. Bull fell in his tracks. I prefer hitting the shoulder blades if the angle allows it. Always try to aim center of the lungs though.
1 or 4 if its over 150 yards or so. 7 if its close. We kill about 25-30 bulls a year on the ranch I guide on, never lost a bull that was hit 1/3 of the way up, lost several from hits that were too high, in the no-go zone, ie through the backstrap.
Results of a 28 Nosler with 195 grain Bergers and shot placement close to the bottom of #5 at 225 yards. Saw steam punched out of his nose on impact. Didn’t drop in his tracks but almost. Staggered 5 yards and was partially down so shot again but don’t think it was needed.
People whom shoot at 7 better have a really good idea where the bone actually is in the neck....that hair is very deceptive...on really old bulls it could be really long at the bottom of the neck..like 8" long..and hair on top could be 6" long....and then it can be really short hair.....missing that bone could lead to a lost critter running quite a ways before succumbing to blood loss... I have shot two bulls with in 10 yards....the first was actually through a small alder tree at about 6' straight on..that bull ran about 200 yards into an opening and was only known to which elk it was because he was wobbly on his feet..but he went another 150 yards to a landing and then fell over into a hellhole.... The other was ten yards..and the broadhead took his heart out of him.....clean pass thru...and I stopped him again at 20 yards..he then fell over into a hole where a tree had fallen over....
Be sure it’s a burger hunting bullet . Cup and core design of the burger is designed to fragment and is asking a lot for those massive shoulder blades . A Nosler Case is on the upper end of valocity and will push the limits of that bullet . DO NOT GET ME WRONG ...... it WILL do the job !!! Will all that horsepower, I like to shoot a premium bonded bullet or solid ! #5
