I have a Remington Sendero SFII in a 300 RUM. I have Leupold Dovetail bases and rings on it. I have right at 40 rounds through the pipe and the ring screws had already came loose? Wondering if there is anything that I can do to keep these tight or will they seat in and not come loose after it is shot in a little more? Just seems like that they loosened up very quick. I realize the recoil is fairly heavy but I did put a break on it to help reduce this. Any info would be greatly appreciated.
