Loading 5.7x28

[ttrailz]

Does anyone have any experience in loading the 5.7x28 cartridge . I am an experienced reloader of 175 different cartridges along with a lot of wildcats . I have not loaded any of these yet but have been absorbing info about all the horror stories involved . I am loading these for an MGM custom encore barrel . I love single shot & bolt guns . Not a fan of auto loaders . Any tricks that you have used because of recurring problems would be greatly appreciated . Also if you have a favorite powder bullet primer combo & would like to share it I’m all ears . Thanks for any & all suggestions .

I had a customer that used to buy this brass.

I know that you don't clean it like normal brass so that you don't remove the coating (this is a semi-auto issue which may not apply to your specific application).

He specifically told me the failure rate on sizing was high, like up to 20%. The necks are fragile and tend to crack on sizing according to him. He also indicated there was a learned feel to managing the handle pull for best results. I am not sure if he used the traditional lanolin oil mix to size or something else.

I think there may be specific Facebook groups or subforums on other sites for this caliber, but the number of people reloading it is small due to the challenges.
