Hi everyone. Google searches for questions kept turning up threads here, so I figured I'd join & go straight to the source. I've been shooting for 25+ years but just started reloading.
You probably get 100 questions a week like these so I appreciate your help and patience with a novice like me.
I'm reloading .223. I have a Lee classic turret press, Lee Dies, & assorted other tools (mostly Lee).
I'm not a hunter or competitive shooter. I'm reloading general target/plinking/training ammo. I have 2 AR's - one 16", one 20", both 1:9, and the rounds I load will come from/go into both. But I do want accurate & consistent ammo. I primarily shoot Fed XM193 & IMI 193. I want to load something similar but probably not as hot unless it has to be. My goal is to not have to change sights for ammo - I want a round of what I load to hit a target at the same place the XM193 or IMI will. I don't expect to put 3 rounds into the same hole at 100M with M193 (not that I'm that good anyway) and I don't expect what I make to do it either. I do expect it to group in a reasonably tight circle though, all at point of aim.
I have 1,000 Hornady 55 gr FMJBT on the way. I have on hand 1,000 CCI #41 primers, 4 lb H335 powder, & 1,000 rds "1x fired LC brass". That should be enough to load 1,000 rds minus anything I screw up or brass that gets rejected.
That leads me to my 1st question. I've gone thru about 1/4 of the brass so far. Cleaned, decapped, sized, & trimmed. My chamfer/deburr hasn't arrived yet so that's as far as I'm going this weekend other than maybe putting in primers. I never saved my brass so I bought some "1x fired Lake City" locally. Turns out that isn't what I bought exactly. First, it's a mix of LC and regular Federal commercial brass. Second, it's more than 1x fired - now that I see the ring that my FL resize die puts near the rim I notice this brass has it. The LC brass doesn't have crimped primers either. But no cracks, big dents, creases, smashed mouths, etc. so I really don't care if it has been fired 1-3 times. I don't think it has been fired more than a couple times based on extractor marks and brass deflector dings. Anyway, from what I've read so far is that if I do everything the same I'll have higher pressures with the LC brass due to thicker case walls. What I don't know is how much a difference in pressure that would be and how that would translate to FPS & where the rounds strike the target. I have a few thousand factory loaded M193 so other than recycling this stuff I bought that will be my future supply of brass. Should I segregate the commercial brass & get it out of the mix now? Or is the difference going to be so small it doesn't matter?
Next, I'm using an ultrasonic cleaner for the brass and RCBS case lube because it's water soluble (maybe they all are - IDK). The cases are coming out very clean. Maybe not as bright/shiny as tumbled, but I'm really happy with the results considering how easy it is. The primer pockets look new. Does that mean I don't need to do any further prep to them? Or do I still need to brush or run a primer pocket tool for some reason? Of course if I do come across some of the LC that is crimped I'll have to take care of that, but if the pocket is visibly clean can I start putting in primers? I haven't done the deburr/chamfer yet but I don't think chucking each case back into the drill would make that process any faster & would probably lead to over doing it. But should I wait until after that step to put the primers in?

I'm still experimenting with my ultrasonic cleaning solution of water, LemiShine, & Dawn. I've had some turn slightly pinkish/copperish in spots around the case mouth. Other than cosmetics, is that hurting anything? I think it indicates too much LemiShine - too acidic.

The 2 on the left are FC headstamps, the 2 on the right are LC headstamps. It seems to only be happening to the LC brass & not all of it -maybe 1/2. I'm guessing the annealing has something to do with it.
How accurate do I need to be with case length trimming? After trimming I'm at 1.751 - 1.752. Should I be chasing that last thou? I'd think with the Lee case trimmer I'm using they should all come out the same - I don't see how I'm getting variation but it could easily be my miking skills that are the defect. It's well within tolerance but I don't know how much variation I should have within the tolerance. I found a couple that the tool's cutter head never engaged and they were around 1.749 - 1.750. I segregated them. Once the load is worked up I'll load those & then next time they'll be longer I guess but didn't want them to end up being some of the first since they were shorter. Am I worrying about something insignificant - is just making sure every one is under 1.760 good enough or is holding them all to as close to the same length as I can get them the right thing to be doing? I'm using http://www.midwayusa.com/product/107333/lee-case-length-gage-and-shellholder-223-remington & http://www.midwayusa.com/product/476992/lee-case-trimmer-cutter-and-lock-stud A random pull of IMI shows 1.755 case length. Does it matter if I'm making mine .004 shorter?
I don't know how my case length translates to seating the projectiles. Looking at the press and how I think it will work is that it's going to put the base of the bullet the same distance from the head every single time regardless of case length - the finished rounds will come out at the same OAL regardless of individual case length variations. I'll see more or less cannelure depending on case length. From inspecting a random box of IMI I see (by my calibrated eyeball) .010 - .020 of cannelure. there is only .002 difference OAL between the round I can see the most cannelure and the one I can see the least so that means either the bullets or the cases are different lengths or the cannelure placement isn't consistent.
My book - Lee Modern Reloading vol 2 - doesn't give me a case length to go by - only a min OAL.
Lastly, when should I clean my FL sizing die? Will it eventually get mucked up with lube, carbon, & debris? How do I know it's time to clean it? I don't think the other dies will get dirty since only clean, dry stuff will go in them, but this one will probably be a slimy mess inside.
