B & C Medalist stock magazine fit????

Finally got the bbl work done on the Krieger 6.5x284 , on action, skim bedded in B&C medalist that is for the centerfeed long action....and the magazine is loose in the cutout on the stock....maybe normal, but is has play frt to back, so do i have it all the way back in the mag well or to the frt of the mag well......the B&C medalist i had for the SA i built the mag went in like the factory stock.....screw spacing is right, so i know it's the right stock #...any suggestions?...Thanks, rsbhunter
