I also opted to change my deer bullet from a "trial run" of 50, older, Winchester-Nosler, Combined Technology (CT), flat based, moly coated (mostly removed), 150 gr., Partitions, now relegated to sight in rounds. These CT bullets are accurate, but comparatively MUCH louder, than tried and true, return to service, modern, 150 gr., Nosler Partitions. On different days I killed one deer (at 50 yds.) and two (take advantage of 20 yd. shot moments) turkeys with the CT bullets. A head/neck shot on a turkey at 20 yards from a rock solid rest is "fish in a barrel" work.
However, with the Combined Technology bullets I completely missed, twice, one each on two separate days, at broadside, 150# plus, hogs that were over 250 yards from the stand. These eyes are NOT that bad. The gun with modern Partitions and I, are completely capable of that shot, though the old scope and old (new to me) CT bullets may not be. The rifle rest is rock solid. The rifle, scope, and CT bullet was sighted in and "right where I wanted it to be" immediately prior to the season.
My approach to each of those shots was methodical, calculated, controlled, and unhurried. My "guesstimate of range" has been laser measured many times before the shot. I know my land. My bullet doping can be questioned as I shot HIGH on both days hitting neither hide nor hair on either hog. Best to miss completely than to hit and injure. My confidence is gone and before continuing to hunt must be restored.
I will shoot the modern Partitions for accuracy to get the rifle, scope and bullet "right where I want it" today. Following that, I will remain and sit quietly to see if anything crosses the range before sundown. At least that is the Plan at 8:30 a.m. on a rainy Monday...
