Just installed the JO BDL in my 6.5 (and sold my OGS!). Snug fit just like Mr. York’s model, but no inletting required. Had a little feeding trouble with the first round down, but I looked it over and pushed the follower spring all the way into the floorplate and that fixed that!
Found out that Mule Deer’s trick of loading from the bottom works perfectly with the JO unit. Chamber a round, then turn the rifle over, open the floorplate, tilt the muzzle down, and drop three (nose first please) into the mag box. Tilt the rifle back so the rounds settle against the rear of the box and close the floorplate and you’re good to go. Tried it at least five times and it worked every time. Kinda like a Howa Krag…..
