Partitions just simply work.

140 gr Partition
.461 BC
2800 fps
1800 fps min for full expansion
Sight zero: 350 yds

3100 elevation Billings, MT
59 degrees F

100 - +5.7
200 – +7.9 inch
350 – 0
400 - -(6)
450 - -(13.9)
500 - -(23.9)

500 – 1986 fps / 1226 ft lbs

Go grab a box of federal premium with 140 Partitions, and sight her in at +5.7 in high @ 100 yds, and enjoy your hunt. At 350 zero, you won’t have to worry about bullet drop until 450 and you’re good to 500 yds for full expansion.

Edit: Go use the Hornady online ballistic calc to determine your proper height at 100 for a 350 zero at the elevation, temp and humidity conditions you'll be shooting at when you sight it in, and then set the calc up for hunting elev, temp conditions to get your drop at 450 and 500 yds for hunting conditions.
