I have the BLR now in my possession and have ordered die sets,bullets,shells and I like the lee factory crimp die.You cannot over crimp the bullet and buckel the case.Just seat the bullet on one step and use the factory crimp die.I have heard loads are potentilly more acurate because all the bullets have to over come the same pressure to release the bullet as all the others.I need to buy more but they are only 9.99 each.Last time i loaded weatherby loads I ruined 10 cases due to trying to crimp them.These lee factory crimp dies guarrenty not to buckel a case of any kind.I ruined several 45/70 shells till I bought that factory crimp die from lee.Give them a try.They don't work on roll crimp I think.Look at graj&sons and they are listed.Drop-Shot
