I was one of the folks who worked/lobbied with the ODNR to expand the list of calibers. This was for a purely selfish reason. I want to use my drilling with the rifle tube chambered in 9.3x72R to hunt my land. Now I can.
I have taken a doe with another drilling using a 16 ga. slug. She took two leaps and dropped. Last season I used a Marlin in 444 and had to track a short 50 yards. Both were lung shots. Both rounds went through. I figure the 16ga left a bigger hole and thus the quicker drop.
All my hunting is on my land and shots are 50 yards or so. Never more as brush and trees make it impossible.
Previous years my hunting was always with a 12ga. slug gun.
The folks at ODNR are true professionals and a real pleasure to work with. For those of you in Ohio I encourage you to attend one of their open houses and get involved.
