I am fixing to start reloading 300 AAC Blackout and have always used RCBS or LYMAN dies and just used their seater and crimp die in 308, 45-70 etc. As of late I have wondered if the Factory Crimp Die would be of benefit to this process? Feel free to wade into the debate and thank you in advance....if it comes out yeah....then I will need to buy some more Taper Crimp Dies for 308, 9mm and 45 acp.....thanks in advance....Paul
