Have been using single shot actions in my rifles with BR actions and 40x actions and have epoxied single shot ramps in 700 actions. All have large diameter barrels which create a lot of leverage on the action especially with a big hole in bottom of action. No I dont carry such rifle around as I have a light rifle for that but when shooting long distance I like a heavier steadier gun shot from a rest. Even a varmint rifle I have is single shot with a sleeve. From a rest, second shots come quickly as cartridge box is just inches from loading port. Realizing the amount of pressure a 2 1/2 foot leverage bar (even a light barrel) has on the skinny little side rails of an action I have loaded rounds one at a time because my long range rifles are single shotCurious, because I have always single fed my 338 edge and rums because I seated the bigger bullets out so far. Became a habit and now I catch myself doing it with my rounds that will feed.
