[QUOTE="MAX, post: 28119, member: 184"] I'm wondering if your case necks are too thick and need to be turned. Necks too thick in a tight chamber can create very high pressures and an unsafe situation. There is no free lunch here. The sticky bolt lift is telling you something is wrong. Mic a loaded round at the neck, then a fired one, same place(before it is sized). The chamber(neck area) of any firearm must be slightly larger than the loaded case neck diameter to allow bullet release. If your measurements do not indicate a larger number for the fired case, you must turn your necks to facilitate bullet release. I hesitate to specify a specific number but .002" is commonly accepted. BR shooters use smaller dimensions but they are using much milder cartridges in the main. [/QUOTE]
