I have been reloading for a couple of years and have enjoyed reading forums such as these. I have found the information very useful in safely reloading my rounds and some of the topics I have seen have been very interesting. I reload 45ACP, 9MM, 223/5.56MM and just started with 270 WIN. The 270 is a gray area for me as everyone talks about alot of differant powders and projectiles. I am starting out with 140gr SST and H1000 or H4831 powders. Any information anybody has using these combs, I would welcome.
