Phillip, A Ching sling has a secondary strap about half way down the main sling body. It attaches to a swivel stud mounted just forward of the floorplate on a bolt rifle. Works like a military loop sling only way faster to get into. Makes sitting and kneeling solid as a rock. Used one years back on bolt rifles, works great. Was hoping somebody on the forum might have tried it. I'm worried if the extra pressure on the fore end of a #1 will muck up the accuracy. ChuckT.
