Does this procedure make a real noticeable difference in the firing of a reloaded cartridge? I've have read and seen some reaming that makes the inside of the flash hole look like a funnel, what can be gained from doing this, speed, firing-time?
Flash hole/Primer pocket reaming

People will argue whether or not there is a benefit to primer pocket uniforming and flash hole deburring, I do both because you only have to do it once and I figure it can't hurt to do it since it eliminates a variable. Then you will get the people who only use Lapua brass because the flash holes are drilled and not punched (which leaves a burr on the inside of the case) like in most other brands of brass, but once you deburr the flash hole what is the difference. If you have a drill you are laughing, once you set the depth stop on the deburring tool you can deburr a brass every few seconds and the same with the primer pocket uniformer.
I did'nt think that a full ream was neccessary, I was of the feeling tha simple smoothing the edges was sufficient, besides, I don't have the time or patience to go that extra mile, The only tiem I recall using something of this configuration, was when I bought some "hot-shot" nipples for my muzzleloader, they were funneled and did produce a better ignition, but you put the nipple on and it stays as is till it is replaced, not funneled every time.......what a pain.
