I use a light weight bipod on my 22 Hornet. I did trim the forearm and put a small foam pad under the tip of the forearm where the barrel touches, also trimmed the forearm so it was not touching the action. Also put the nylon washer around the forearm lug. The other item I have heard about in the forum is making sure there is zero oil on all the surfaces where the barrel and action meet up. I guess it kills accuracy if present.
When we use the bipod, we wrap our non-trigger hand around the front of the trigger guard. Seems to work just fine for us. It took a little doing for us the stop grabbing the forearm.
Good luck.
