When I was a young man with good eyes I useda rifle in 7 x 57 with iron sights. Took a couple deer with it and it performed very well with some handloads my grandfather cooked up for it.

Still have the original box and recipe in his handwriting....
Wincheter brass, CCI primer, 36gr of IMR 3031, pushing a 160 gr Sierra spitzer BT. It was modest speed and recoil, accuracy was ok in my rifle at 100 yrds with the open sights. My eyes can't keep up with the rifle anymore though.
