Best bag???

There is not one bag that is best for all, and to be honest, there is no best bag for YOU when switching different stock/bipod combinations.

Bipod height, comb/butt height & parallelism, the size of your chest..etc... all plays in.

I'd suggest you start out with a mid sized bag, if its too big, loose some of the fill, too small, add some. You don't want it to be really full or really empty either though, as it wont offer firm support at all.

If all your doing is bench shooting, why would you want a field style bag though? You would be better suited to something leather/sand/with ears.
 
Guys,

Need advice on the best bag for my bolt guns. AIAX 308 and AIAW 6.5 creedmoor. I shoot mainly from bench, not prone. Thanks

Since you're talking about shooting and not transporting Im leaning towards a rear bag. Ive got a protector DR bag, 15lbs, very solid.

Yep, TestnDoc must be talking about a shooting rear bag; the one you have is very good, I used it yesterday. That's an heavy little guy so if I were to have to carry it around, I would go with something lighter but as he shoots mainly from a bench, it would work perfect for him.
Good shooting.

I use the Protektor medium sized leather bag with the medium ears. Whatever bag you use, make sure to use a heavy sand fill. Makes it able to do fine adjustments and hold very steady.
