Filling barrel channel of a wood stock

[montana_native]

I've recently rebarreled from a #5 contour to a #3. As can be imagined, I have a pretty large gap in the barrel channel now. Is there a filler that can be used that has a "wood-like" appearance? Thanks.

I did something like this once, came out to my liking. I wrapped the #3 barrel with three layers of electric tape in a uniform spiral no overlap wrap. I then wrapped it with two layers of Teflon pipe tape the same way. After protecting the stock with masking tape I spread a generous layer of common epoxy in the barrel channel. I then just placed the wrapped barreled action in the stock and snugged the action screws. Wipe off the overflow epoxy and wait for cure. Might take a mallet to shock remove barreled action. Strip off all tape from the barrel. Sand the rough spots, fill and sand holes if needed. It left a nice uniform .025 or so gap the full length of channel. I just spray painted the epoxy to match the main stock color. Most of it does not show any way.
