The two-point
British
sling is indeed easy to get into, but less solid. The sling will slide down the tricep and get out of position unless there is a button or something to rub against. There were a few old school DCRA shooters using two-point slings when I was new in the game, but overwhelmingly everyone preferred single point slings.
The issue web sling is really a carrying strap, not a marksmanship aid. However, if the shooter can wind his support arm through the front end, the rear portion will come across his chest. If the sling is short enough, it will give support. Too long and nothing works. But too short and the rifle is uncomfortable to carry over the shoulder.
Hunting magazine editors have a long list of topics to assign to their writers, but few articles actually seem to have new information. So in between the debates over magnum or belted or short fat cartridges, scope zeroing, rifle maintenance, jerky making recipes and photospreads of successful hunts (how come my deer never look so magnificent as theirs?), someone writes a splashy article discovering how the Acme Brand sling will improve readers' shooting accuracy. Revelations! And merchandising opportunities abound! Then as the cycle moves, the next big thing will be Anchor Incorporated shooting sticks to rest the rifle on. New revelations! And more merchandising opportunities on the horizon!
