I have recently purchased a stormlake match grade barrel, I purchased some 180 gr tc loaded to a 1.12 oal and low and behold it won't chamber! I used the redding push theough die and also have the lfc die. empty resized casings drop right in about a thousandth below the hood. Soon as I seat the bullet where the cone stops and the straight begins that hits the step the mouth is supposed to headspace off of. I believe the leade is a little to tight to let the bullet in there. I have measured everything, the chamber size is .4245 the barrel size is .4005 and the chamber depth is .8559. The only way I can get correct headspacing is seating dangerous deep as in 1.09. any suggestions? I left a message at sl tech dep but they were gone for the day. I truly believe the leade isn't cut big enough to let the bullet.in at the. A proper oal am I on the right track?
