Since typical combat ranges were typically between 100 and 300 yards, manufacturers set about developing intermediate-power cartridges that were more powerful and had a longer effective range than a pistol cartridge, but had a lighter recoil than full-powered rifle cartridges. Full automatic fire was much more controllable with those sub-machine guns, but they didn’t have nearly as much stopping power or as long of an effective range as full-powered rifle cartridges. However, they also had a lot of recoil and were difficult to handle in a fully automatic rifle.įor that reason, the various armies supplemented the rifles the infantry carried with a number of different sub-machine guns chambered in pistol cartridges (like the 7.62x25mm Tokarev, 9mm Luger, and. These rifle cartridges were quite powerful and capable of engaging targets at ranges in excess of 600 meters. 303 British, 7.92x57mm Mauser, and 7.62x54mmR in their primary infantry rifles at the beginning of World War II.

My Troy di-optic rear site proved to be too wide for that task so it has returned to the interwebs from whence it came and I replaced it with a KAC. If you take that approach make sure to use a rear sight with a narrow aperture so you can see through the optic and stay on the sight plane. The sighting system I’m using now is flip-up BUIS for supersonics and my Aimpoint T1 for subsonics. Again this not much to remember and 2″-3″ is not a lot of deviation without doping. That setting leaves me 2″ high at 25 yds, 3″high at 50 yds, back to 2″ at 75 yds and zero at 100 yds. For the subsonic zero range: 10/100 yard zero. Figuring out holdover on the fly (and without a dual-reticle optic) is a nonstarter in this case. Now to compare the blue line to represent subsonic rounds to the red line- big trajectory difference as one would expect. That’s not too much to remember and even without doping shots hits will deviate by about 2″ or less at any range from 0-250 yds. This leaves me dead on at 25 yds, about 2″ high at both 50 and 100 yds, back on zero at 150 yds and 5″ low at 200 yds.
