Current times the ranch to the N has been doing better management and runs their pen traps three times a year. Larger hogs get removed and sold to the packing plant. What is left is the little footballs that quickly grow to 75-150 lbs.
Switched over to the Ruger Ranch in 223. Quality commercial loads are 3200 fps and SP’s expend their energy quickly. Currently purchased a case of 1K V-Max, a good neck shot shocks the spinal cord and they go down. With multiple pigs in the kill zone @140 yards, shots are planned with largest first and have about 1 second to hit 1-2 others before they realize they are in danger.
If the larger hogs somehow recovers from the shock, multiple follows up can be placed to keep it down.
