2 Reloading questions

[Tactical30]

First of all i am somewhat new to reloading, I have only been doing it for a couple months. I mainly reload for my AR setups
(.223,6.5 Grendel) for target shooting from 50-600yrds. Anyhow my 2 questions are:

1.) Do you have to chamfer and deburr again <span style="text-decoration: underline">after</span> the first reload? I deburred and chamfered the first load and went to the range and let em' loose, I noticed when I was going to reload them for the second time where I had first chamfered they looked kinda burred (not as smooth as initial deburr, probly cuz of the firing of the bullet) I lightly deburred again to smooth them out so I didnt scar the next bullet up when seating. Is this normal?

2.) I use the RCBS Trim Mate Prep Center to do all my case prepping (flash hole deburr, chamfer, Deburr, Primer pocket brush, primer pocket uniformer,flash hole uniform, military crimp removal (if needed) I noticed after I primer pocket uniformed and then went to install the primer, it felt like the primer was more easier going in (none fell out tho) as to just primer pocket cleaning with the primer pocket brush. When I used the brush the primers felt more tight going in. I would think primer pocket unifoming would be better than just using the brush.
What should I do in this situation?

Re: 2 Reloading questions

1) deburr new brass and again only if you trim case length

2) more damage is done by incorrect/excessive primer pocket uniforming.Do it with reloads on crimped primer brass or with brass that you have difficulty priming

Check your brass after 2-3 loads to make sure that they are within max length so that they chamber easily. When trim your brass, you need to chamfer and deburr the mouth

Unless you are looking for that elusive minute improvement in your accuracy, or you have lots of time on your hand to prep your brass, there is very little returns in doing so. When do it incorrectly, you may lessen the life span of your brass.
