I checked a few bullets for depth to lands and found that none of them could be loaded in the magazine of my S&W, M&P15PC-1 Talo Exclusive rifle. This is supposed to be a highly accurate rifle. For example, a Hornady, .224 dia, 75 grain BT A-Max in my rifle has a depth to lands of 1.982" giving me a COL of 2.514". The Hornady manual for this load states a COL 2.390". Even this will not likely fit into a magazine. This was the same for the Sierra 69 grain, HPBT and the Berger 70 grain VLD. The VLD was a bit closer though, by about .050". I realize that single feed is the way to go for bullets loaded very close to the lands, especially for bullets such as Berger Bullets, and I have every intension to do so, but, what about those shorter 55 to 60 grain bullets? Won't they be way, way off the lands to be even close to being accurate? With such a large jump, will that erode my barrel? Should I be concerned?
