Thank you.
I thought something with 61 ft lbs of recoil energy would handle the 222 5 ft lbs of recoil. I guess the 11,000 lup vs 50,000 psi make the difference. The orignal 158 toppers came in 22 hornet, 30-30, 155 Shikari 44mag,and 45-70 circa 1979. Would these calibers work. When did H&R start making 10 gauge.
