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.
I've read a bit on the forums here so this is how i understand it. Any point I am wrong on please correct me, i'd hate to put out bad info.
I think some of it has to do with what glock you have, the newer ones have better support than older ones.
you don't "need" an aftermarket barrel to do reloads. As you stated you don't plan on nuclear loads so it shouldn't be an issue if you use decent brass. (lots of people say stay away from the PPU pistol brass)
Mostly you want an aftermarket barrel if you are reloading a lot of full power loads.
I've done underwood loads through my gen 4 g20 and no issues with the brass.
kkm is a great barrel, definitely has good support, tighter than stock but on occasion there may be some hangups if the load isn't good enough, tighter specs give less leeway if something isn't right (such as bullet shape, seated incorrect depth, case expanded too far and didn't resize properly)
How hot you can go is really up to you. not all loads fire equally out of all guns, and it's up to you how far you want to push the safety envelope.
