anyone notice a difference in poi when doing this??? noticed some range brass for sale with mixed headstamps...jst wondering if it makes a huge difference to plinking loads.

I reloaded a significant amount of 9mm a year. This year I reloaded around 16,000 rounds. I use all sorts of headstamps, whatever I can get my hands on, and there is little to no difference in POI with my reloads. Even at the chronograph, I am pretty consistent with shooting 1,050 fps +/- 10 fps with 124gr CMJ Montana Gold Bullets. At times some headstamps might be around 10 or 20 fps in difference, but my 25 yard static groups are the same whether I am shooting all starline brass, or a mix of everything brass.

My .223 plinking ammo had mixed headstamps. I'm not trying to shoot tiny little groups with it, all I know is it's accurate enough for my needs.
I shoot mixed headstamp brass and never noticed anything for range/practice ammo. I never looked for it but never noticed anything either.

For plinking loads it won't make any significant difference.
As noted above I haven't had any issues when in the plinking pressure range but you might encounter problems when loading close to max. Good practice is of course to work up to max or near max in small increments checking for signs of pressure. Having a load that's safe in commercial brass might well put you beyond safe limits jumping over to brass with less capacity, military brass for example.

I don't bother sorting headstamps on my .223/5.56 brass, other than to toss out ones I'm specifically avoiding, even when loading up stuff like OTM match rounds.
I'm not shooting anything with optics over 4x, though, so between me, the rifle, and the optic I'm not likely to notice much difference if I'm doing everything else right in the reloading process.
With some other brass, like .308, I'd do it differently, though.
Truthfully I don't mess with sorting by headstamps on "most" handgun cartridges or my 223/5.56. Most of these are practice stuff and not maxed out loads. I have yet to see any noticeably larger groups. However for most of my hunting or serious work loads I do sort by brand or headstamp and often keep separated by different lot numbers.
I only sort off brass if I know a specific headstamp needs a crimp removal or something. After that, I couldn't care less.
