Thank you for your most informative video. I'm about to embark on reloading for the first time and this has been immensely helpful to me. The tricks of the trade so easy when you know how. Many thanks from Scotland.
Honest to goodness, this has been the most straight forward helpful and informative video on this topic I have seen. Thank you very much. Definitely Sub worthy.
Hello, I'm from France i have just lost more than one hour in search on the net for know if the depht is adjustable on the rcbs tool....And i found this video! Thank you very much! : - )
Read Lee’s book. The first half. Since 1975, I have found a “dirty” un-uniformed primer pocket has no bearing on accuracy. I can assure you that , if you make a case weaker, you are buying into an unneeded practice. Don’t thin any part of any case. Don’t make sense? Weakening of any part of any case is absurd!? Really
After reading that same book I have been contemplating that very same thing. I have a hard time buying into it effecting accuracy. I seat primers till they are bottomed out. I do not uniform pockets and have had zero issues with accuracy or anything else for that matter
Sinclair uniformer is a one piece tool, doesn't need adjustments and can't move on you. There may be other brands that are made the same way. One less thing to worry about.
I have several similar things and use them. Every once in a while though you can have primers that don't sit flush so you need a deeper pocket than usual to prevent slam fires.
Is there a problem if you uniform your pockets deeper than the depth of your primer? I have done this and had no problems as long as I seat my primer flush with the bottom of the case. I also ensure that I am not taking off too much material out of the primer pocket. What do you think?
Just the opposite - a high primer can be very dangerous, especially in a semi-auto because you can get slam fires or out of battery explosions. Your firing pin should have plenty of protrusion to get to a primer seated a little below flush. (Firing pin protrusion on an AR-15 is usually around 0.030" for example.)
At 1:51 in the video I included the SAAMI specs. At the bottom it says seat the primers from flush to 0.008" below the face of the cartridge. A slam fire is a round going off when the bolt or slide closes but might not be locked. An out of battery explosion is when the round goes off before it is completely chambered. Either can cause severe damage to the weapon and personal injury.
so you would rather have a recessed primer than a flush one for those safety reasons. Obviously this is not advised but can you go slightly deeper in the primer pocket than SAAMI specs as long as the primer is not seated lower than 0.008" below the face of the cartridge? Lets say you needed to go a few more thousandths to get uniformity.
Haven't had a problem with mine. I'd bet if the setscrew was loose the cutter would just push back in until it pressed against the adjuster, so you'd be OK.

You're welcome!

Nice calm style on top of being informative and no annoying bla bla bla. Well done!
Thanks!
Excellent video... short, simple, informative and to the point. Neat trick with the paper hole puncher. shoot lots and stay safe.
I wish RCBS would have videos like this for some of their products. fantastic video
Thanks, this really helped... There was always that 1 in 10 or so cases where the primer would stick up.. moved the cutter out ~2 thou and voilla!
Great video, very clear and explained wonderfully, the paper punch is a great idea.
Excellent and straight to the point. Thank you!
not a lot of excess talk just plain good info
Solid video & good camera work, thanks for taking the time to share your knowledge & experiences with us. Take care,
You are certainly welcome!
Straight to the point .

Thanks for doing this. J.
You are welcome!
excellent video
Cigarette papers are an old machinist trick for a .001 shim.
Thanks for the video!! Where do you buy the primer uniformer for the prep center... I have the rcbs prep center.. Thanks again for the video.
Thank you. It's been a while but probably from MidwayUSA (who still sells them)
Thanks again

so are there specs for how deep you should uniform and where can I find them? What is a slam fire or out of battery explosion?

Look at the SAAMI sheet again - 0.008" below flush is in spec.
Going deeper won't improve uniformity - it will just seat the primers deeper.
Any problems with the set screw coming loose on the RCBS uniformer and the depth of cut increasing?
Haven't had a problem with mine. I'd bet if the setscrew was loose the cutter would just push back in until it pressed against the adjuster, so you'd be OK.
That moment you remove the set screw & realize it broke off inside.
