If you are unable to use a squeeze bag due to injuries to your supporting hand I would recommend a good wedge bag. Instead for squeezing it you can slide it forward and back or side to side for elevation adjustments. I run a bipod for most shooting where I can have both front and rear support, but shoot off a bag when I can not. PM me and I'll send you some pictures of the wedge bag I have. I have since retired it from use due to finding a bag that is more universal for how I shoot and compete.
