Marlins guy and SS Dave have the answer for octagon bobs. I don’t think the tool I use for round bbls would be a good choice for the flats. It’s impossible to control that tool with your hands that far apart and any rotation of your hands would be multiplied by the distance your hands are apart. When I’m doing flats I keep the fingers of my hands as close as I can to minimize rocking. I made a tool to hold the bbl for flats work but I can’t find the post that shows it. Anyway here are a few shots as the stock stands. It has a couple of coats of Chambers oil and the bling of the buttplate. I may refine the grip lines a bit.

Earlier, during the discussion of checkering, I was undecided, and stayed mum. Now, with the finish upon the beautiful chunk of lumber, I have decided to make my choice in favor of not checkering the butt. The grain, running from side to side is stunning on the end grain and is perfectly framed by the pair of plates at the heel and toe. Even little points serving as arrows to direct the viewer to that feature. I wouldn't change a thing. Another build from the numerous builders here found. 

Hi guys thank you so much for the kudos. I really don’t know why I can do this quality of work, it kind of comes naturally. My last name is Martel and my father had the same talent. Here’s a snippet of the name “ In modern times, the last name Martel continues to have a variety of connotations. Many may view it as a tribute to the Martel family members who were skilled workers and artisans in the distant past, while some may use the name to indicate they descend from a long line of metalworkers. Generally a strong and proud name, 'Martel' continues to be a common and well-respected surname in these times.” I guess it’s in the blood. 
Thanks for looking and I appreciate your comments

Thank you Otony! Well except for more coats of oil and a bit of refinement the butt stock is done except checkering. Most of the metal work is done including an DZ arms extractor. I also need to make a few screws too. Our first match is coming up in early April and I’ll be spending the next couple of weeks finding what this .22 likes to shoot. I’ll be competing without the forend as that is the next step on this rifle. I’m going to go “old school” on the method of attaching the forend to the bbl. I’ll use a key or tenon with a tasty inletted escutcheon. So next step is squaring up the forend blank on the table saw then milling the barrel channel close to final dimensions with a 1.00” ball end mill. Stay tooned. Oh! The the scope is a 10x MVA scope with Dan’s (DZ Arms) mounts a winning combination.

Getting back to using handles like yours, it was/Is my intention to keep the handles as close to the work as possible. If it doesn't work, then I will go back to my old way like marlinguy's, except the use of steel, as I feel the weight helps. Have in the past even thought of using hard lead. May try that also. Regardless, your work is impeccable. There are few who reach that pinnacle.

Excellent work!!  I hope you document your forearm attachment,  I've always wondered how to do this.
