In 2020 I built (3) rifles and shot (3) deer.
The rifle pictured is a 250 savage with a 20" Bartlein barrel with 8" twist.
The rifle with bipod, sling, rear bag, scope, and ammo is 7# 14 oz.
Wimpy cartridge with short barrel killed a mule doe at 200 yards.
For shooting deer at 600 yards, I would need a longer cartridge and longer barrel....and it would weigh 10 pounds.
