Can these be attached to a balistic helmet

Attached ? No. But they fit comfortably under standard ACH.

Do they come with a case to carry them

No I bought a separate case to carry the earmuffs and my eye protection. Here's a link to the case on Amazon. https://www.amazon.com/gp/product/B07BVD2JW9/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

what is the recommended NRR rating for indoor shooting with large caliber rifles?

??? Don’t know. I know they work where I go indoors. Next lane can be shooting 308, shotguns. I’m shooting a 9mm between lane separating walls and they work.
