That is the way to do it, SB. No matter what the trajectory of your bullet, a hunter needs to know what it is and to know what limitations it causes. I choose to use a higher velocity, even though it makes only a small difference in POI out to 200 yards, just because the powder coating makes it easier. I also choose to shoot deer through the chest cavity to avoid meat loss and it was only my failure to hit properly that caused the meat loss in this kill.
I also shoot my loads out to 200 yards just to insure I know the POI. Unfortunately, I only have a 100 yard range on my property and have to load up everything and go to the hunting lease to shoot farther. It's a little bit of a bother but is still fun....and, I can assure myself what the load is actually doing beyond 100 yds. I have no intention of shooting at a deer beyond that distance with cast although I probably could stretch the effective distance a little if I wanted. When you get beyond 150 yards or so, regardless of having a slightly higher muzzle velocity, bullet drop increases too rapidly with small increment of distance. This isn't a problem when clanging steel and there is plenty of time to consider bullet drop, but in hunting conditions it can cause problems getting a killing hit. As I stated, The deer was rapidly walking across the easement and I had to make a snap shot. If he'd been farther away, I would have had no time to consider trajectory and made the necessary adjustment in hold over.
Again, it was my poor shooting that resulted in the unnecessary meat loss. My intent of posting the pictures was to illustrate the effectiveness of a cast flat nose. There were two surprising results from that experience. First, that the deer went as far as he did considering the damage done. He crossed the remainder of the easement plowing the ground with his chest. He was going down a steep hill which helped his progress. I assumed he would be dead at the treeline of the easement. Somehow, he managed to make it another 100 yds or so after leaving my sight. Second, despite the massive damage all around it, the heart was untouched! I grilled it Friday evening and it was excellent. The rest of the meat is still aging and I'll cut it up tomorrow afternoon.
