I've hunted with HK rifles for many years. Mainly used the sporting rifles( 270, 300, 630, 770, SL6, SL7) But I did sneak a 91 out for whitetail one season years ago. The HK's are great hunting rifles but I'm a little biased. I live in a state where there is no mag capacity restrictions. So a 91/93/715/716 with 20-30 round mags are fine. There are 3/4/5 round mags available for the HK sporting guns.
