I'll use the 100gr. .257 in 14 twist .250s, they shoot well and behave appropriately on game at those velocities. I like the .308 165 gr. hot-cor as a cheaper practice bullet than the same weight partition. Same for the .358 250 grain bullet in the Whelen. I shot a 6 pt. in the neck at 6 yds with the .308 200 gr. in a .300 H&H, at about 2850. Almost beheaded the deer. Shot two deer under 25 yards with the 150 BTSP in a .270. They behaved about like a varmint bullet. Killed the deer, though. I also shot a four point in the chest cavity with a .308 165 gr. RN from a .300 savage. Looked like the deer just deflated. Great bullet, I miss that one. Last, I shot a decent sized doe at 8 yds with the .41 cal 220 gr out. Of a 10" contender. Entered the chest, broke most of the ribs on one side, transected the abdominal cavity, and exited the opposite hip. Messy gutting job, but no tracking. You could say I like them, but when used within their limits.
