I was wondering if anyone else had a problem with this before?? I had a model 12 action chambered in .223 and wanted to re-chamber it to a .243 win well I order all new parts for the bolt such as baffle, bolt head, and such well when I installed everything minus the barrel the bolt was so tight so I sent it to Kevin at stockade guns and he had to time and true tat action to make it right.. Well i want to do this again but in a different caliber and don't want to run into the same problem of having to have it timed and trued just install all the new parts..
