I have an old Jeffery rifle, manufactured in 1920 chambered in 404 Jeffery. I plan to hunt a buffalo with this "grandpa" rifle this June... and i will do my best with iron sights.
I feel is like a "sin" to drill this old british rifle, to add him a scope... so i will not do it. I have tested the rifle at home, and shooting it for practising, and the recoil with 400 grains bullets is quite mild for such a big caliber.
Really i can't wait the moment to be in front of the Buffalo with the old Jeffery in my hands.
