I had a gunsmith to mill my R700 action to fit in a Wyatt’s 4” magazine box. I’m building a 300 RUM.
I’m using the Remington ADL Tupperware stock and needed to relief cut some of the stock to get the Wyatt box to fit. I used my die grinder to get some clearance. The box fits into the stock now snugly. I had read you don’t want the box to be tight or loose.
What would be the best way to determine the fitting of the magazine box?
Thanks
