Tight primer pockets and case prep?

[greg11]

How do you guys address tight primer pockets? I don't have a swag yet, but I've heard chamfering the pocket a little helps it slide in. The few I've tried this way don't see much of an improvement.

Also, if I've prepped a case by trimming to size and chamfering the inside and outside of the case mouth, must I repeat the process on subsequent reloads? Or just touch up as required upon inspection?

What exactly does the chamfering process "do" in terms of performance?

get a primer pocket swager like the one offered by RCBS it expends the primer pocket out and removes crimps, i use if for the tight pockets on S&B brass or crimped primer pockets. I only chamfer and deburr if i have trimmed the brass otherwise i dont bother. Chamfering the pocket only removes crimps it doesn't deal with tight pockets. Chamfering removes burrs from the trimming process

1) tight primer pockets can be done with either a pocket chamfering tool, or a swage die. Swage die is better IMO, and I have tried both methods.

2) Yes, you must repeat the case prep on any case that you have trimmed.

3) Chamfering has nothing to do with performance, as chamfering is a method to remove and sharp edges or burrs on the inside of the case neck; but most importantly, it allows a slight angle to the inside of the case which makes it possible for the bullet to sit in the case much straighter and easier.

x2 - I've also tried both methods on primer pockets and a RCBS swaging tool does a far more consistent job than simply chamfering the pocket mouth. You may also choose to uniform the flash hole so ignition is more consistent.
