I killed one of my 3 antelope this season with my 99 in 300 Savage with a peep sight. Didn't have a camera on that hunt (like most times) so no pics.
I used a 140 Hornady Mono Flex and a charge of 41 grains of 4064. The kill was from about 160 years away. The bullet worked super well and the wound was straight and pretty wide.
But still I can't say the resulting hole was actually better then what I have got in the past with 150 grain Remington Core-Lokts. Might be a better bullet for elk or bear because of it's ability to retain it's weight, but for deer and antelope I can't see any real advantage.
I have tried 3 different powders H4064, H4895 and IMR4320. And 6 different bullets (150 grains with a Hornady interlock, the Remington Core Lokt and the Nosler Ballistic Tip Hunting. 180 grains in the Sierra Pro-Hunter and also the Remington Core-Lokt, and the bullet above, the 140 grain Mono Flex Hornady) In my 99, and the old Remington 150 grain has (so far) been the most accurate. Just barely over 1" groups at 100 yards, which for my old eyes shooting the peep sight is excellent. All the 150s and the 140 shot under 1-3/4". The 180s both shot to about 2.5" to 2-3/4"
I think I will just marry the M99 to the load with the 150 grain Remington CL.
If I can get my Remington M81 300 Savage to shoot 180s under 2" consistently I will probably marry it to that load. So after that if I want to use 180s I'll take the Remington 81 auto, and if I want to use 150s I'll use the Savage.
