I have observed guys using the hand tool for this or weak cordless drills and most are not getting proper depth or square you really need to make sure you are deep enough and square. I do this by using plug in drill and making sure rub marks are uniform around the primer hole and no more chips are coming out I the double check with a hole depth gauge I made up myself. Any thoughts on this !! from other experienced re-loaders?
 
I use a Sinclair uniformer in a CT drill press. I also look for uniform removal around the pocket. I do not measure it after. I also clean said pockets with a quick touch on the uniformer again.

I was using a Sinclair until I found K&M way better! $22

I've used the Sinclair in a drill press for years. Like the OP I think it needs to be done properly to get the bottom square. Also it's a great tool to get the crud out when used sub sequently

I uniform every reloading on my .338 LM brass and i am not loading hot at all although not much material to remove.

How is the K&M "way better" then the Sinclair - which by all outward appearances is the same?

I've been using the Sinclair for years without a complaint. I've never bothered with a drill/press, 2 turns by hand and any brass I've encountered is uniform. I don't use mine to clean primer pockets, I only uniform shiny clean brass.

Yes you are correct I just checked the one I have and it is in fact not a Sinclair:redface: I do not know why I was under this impression that it was a Sinclair maybe because I have so many other Sinclair tools and could not believe I bought a Lyman uniforming tool:redface: I did buy it from Sinclair International that's where the similarity ends though the Sinclair is way superior looking. I do like K&M tools though I bought the KM neck turner with expander mandrels will make a report how this set up works once I pick it up! Again sorry for the confusion! I reload .50 BMG and .338LM and definitely need a drill to get correct depth and be square. I do throw brass in the Ultra sonic sometimes and have perfectly clean brass but only if time permits.
 
For my .223 & 6 br. target rifles I will use the Sinclair uniformer on new brass for their first firing. Have never found it needed after that. (just makes me feel good doing so.) Have done testing by shooting prepped pockets and ununiformned pockets and can tell no difference. I think a benchrest shooters may be able to see the difference on paper or over a chrony. What I do find important is to deburr the flasholes. It is amazing on how much of a burr can be around the inside of a flash hole on some brass.
 
The tools like Sinclair that are machined from one piece are prefered. The Lyman type with a collar can loosen and then the depth is not set right. Since the prices are all so similar the Sinclair was an easy choice.
 
I have both the RCBS and the Lyman and I can tell you that the RCBS beats the Lyman hands down.

I have some Sinclair tools including the Sinclair/L.E Wilson Ultimate Stainless Trimmer and whatever I have bought from them has exceeded my expectations.
I guess I'll add their primer pocket uniformer set on my next order.
 
I have the K&M and think it is great. any tips on how to not have to hold the brass in your hand while using the cordless drill? After 100 new brass my hand is pretty sore from the ones that grab. I usually just go slow and remove the tool from the pocket a few times like the instructions say but every so often one grabs. Granted this is with new brass only. When used on fired stuff it is fine.
 
I got a pair of Firm Grip Nitrile coated gloves at Home Depot that were said they are very grippy on the package. They are indeed. I use them to hold my cases when I trim them in the Giraud. Makes them very easy to hold, even when still covered in lube.
