I shoot a lot of Hunter matches. Here's what I suggest.
1) Tripod. I'd run a match without a bipod before no tripod. You will not be able to shoot all prone. There will be positions where you need to shoot standing in many matches. Figure out if you want to clip in (via ballhead or anvil) or bag on the top of the tripod. Both work, personal preference.
2) A good bag to shoot from rocks and other positions. You will be able to shoot many positions off tripod vs. a bag but some stages may be better with a bag.
3) Rangefinding binos. It's quicker and easier vs. a straight R/F. Many folks do use binos and a R/F so it does work. Bring what you got until you decide the matches are for you.
4) Pack for all your stuff. Practice with your tripod and gear in different places and see which is the most efficient for you to get your gear out quickly to start scanning for targets.
5) One MOA rifle or better. You don't need a tack driver. Target sizes are generous. If your rifle can shoot one MOA practice shooting off a tripod, rocks, tree branches, etc. before spending hours trying to shrink your group size.
6) Figure out how you want to run dope. Whether you're using a pre-made dope card for different density altitudes or using your R/F or binos that provide dope. Getting an accurate range and dope quickly is paramount.
