Until very recently I had never reamed or uniformed a primer pocket in any of the rifle calibers that I reload. I used an RCBS wire brush to clean them but that's as far as it went. Priming (on a LCT or Redding T-7) was never my favorite step in the process just because primers didn't always seat easily even though I had developed a pretty good feel for seating them.
Recently though I had a problem with a few FTFs in 30 carbine which I traced back to primers not being fully seated even though they felt OK.
I decided to buy an RCBS primer pocket uniformer and attach it to my FA case prep system in place of the wire cleaner brush. The difference it's made is unbelievable. Every single primer seats easily (but not loosely) and there's no mistaking that each one is fully seated.
If you don't already uniform your primer pockets, consider doing it. If you already clean the pockets, it doesn't add a step, it just replaces the cleaning. Some people say it also removes military crimps but I haven't tried that yet. It would definitely be an added bonus if it does.
