The factory MKX contour is too light in my opinion. Yes it worked for 30 yrs. but I want a touch heavier without going to a target barrel. Since I built the stock there is no issue in expanding the channel. Going smaller would be an issue.

In looking at the supply of bullets I have on hand I have several 1000 in the 60-69 gr range. I "believe" the factory is a 14. I do need to think going with a twist quick enough to shoot the 69s.

Just my 2 cents.
