Hello fellow 10 Ringers! I've been member on this forum for a long time, but I have not noticed that there is a separate sub-section dedicated for the 10mm. I'm glad I found it. I recently got a G29 and after reading bunch of your posts on after market barrels, I'm still debating - do I really need one? Do I really need and after market barrel for better chamber support when shooting reloads? How better is the support from a KKM barrel vs the stock? How hot can I go with the stock barrel? I'm planing to load 165 and occasionally 180gn coated and plated bullets. I will probably stay off the nuclear loads untill I get a chrono so I can exactly see how fast Im going. KKM is my choice If I decide to get an AM barrel. Id love to hear your inputs and experience, especially from you realoaders out there.
