Boss just tried your method. I got back a 284 win match from Nate 308. I was using 6.5x284 Lupa brass it worked great!!!!! I didn't even have to size it up, just primied put powder in then a little cotton, and it blew neck to the my chamber. Beats the heck out of lubing, and sizing up. Thanks again Boss for sharing your knowledge.....
Glad you liked it---if it works for one of the best smiths and shooters on the planet then it is good enough for me!!
