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 only sort off brass if I know a specific headstamp needs a crimp removal or something. After that, I couldn't care less.
i only due it with my bolt rifle. As lousy as i shoot it, i dont know why i do but i do.

I've reloaded thousands of 9mm over the years. I was told early on that due to the very limited space in the 9mm case and the differences in space from brand to brand that I should separate cases by brand. I did this for years, then got lazy and stopped. I don't load to high pressure, I load for competition, low recoil, muzzle blast, etc. The few times I have loaded a batch of high velocity loads I used once fired brass in good shape from one manufacturer. Case capacity will effect pressure, velocity.
