Re: What shooting rest bags?
I have one that's just the front rest. It's not a $3,000 bench rest competitor's dream. But, it works really well with my Savage 12F and the wide flat firearm.
It's stable, with a relatively broad coarse adjustment range, and fine adjustments are easily managed with your free hand.
I shoot most of my other rifles from bags or bipod since it's pretty bulky to lug around.
I think you'll like it.
