Free Floating Barrel

I just got my Remington 700, 7mm RUM barreled action back from Hart, put it in the HS stock and torqued the action screws. This barrel has a slightly different contour than the original. I used a sticky note to check clearance between the barrel and the channel in the stock. It seems I have plenty clearance except in one spot, about six inches back from the end of the stock, where the sticky not drags just a little. I know I have clearance or I wouldn't be able to pull the paper through this area. I this enough clearance?

Thanks for you help.

Not in my opinion. Put some sand paper around a round wooden dowel and sand a little of the stock material away.

+1

It may touch under use or changes in support positions.

Re: Free Floating Barrel

Thanks guys.

It passes the dollar bill test so I guess the sticky note is a little thicker. Is the dollar bill test adequate? Do I need to worry about removing too much?

Re: Free Floating Barrel

The dollar bill test is nice for looks, but useless for functionality. Put some sand paper to that barrel channel and open it up until it passes the 5-one dollar bill test. Five one dollar bills stacked together, or five sheets of standard writing paper.

You want enough of a space between the stock and the barrel so the barrel never touches the stock under any positions or conditions of fire. That barrel touches the stock as the bullets in motion down the barrel and there's no way to know where that bullet will impact - compared to the barrel not making contact with the stock.

I believe your stock is pretty stout/stiff - which is why five thicknesses of paper is likely to enough clearance. Some of the cheaper plastic Tupperware stocks require even greater separation from the barrel because they'll flex and bend so much more easily.

Put a spittin' gap in that stock all around that barrel - a little larger toward the end of the stock than near the receiver.

+1 I sanded my HS stock so that I could run my buisness card down it without touching .
