I know the AEA stuff and Challenger (Not LB) are mostly 303 from what I have been reading.. Curious if anyone has slugged or knows if the newer Long Barrel is also 303?

I have one coming next week and wanted to check before ordering the 303 slugs.. Have some HN HP's coming initially which are .301

Thanks
Mike
