Orange, black, and yellow settle down considerably. I’ll probably split the difference between black and orange. Green was promising but it’s lies outside the other groups kinda by itself.
Referencing your charges that correlate with each color help readers follow along. ThxI shot my last set of tests for TAC and the 52 grain Match Burners. It appears I was a little under the optimal charge. The load I was using is purple, with the other shot below the paper. Orange, black, and yellow settle down considerably.

Ah, right.Referencing your charges that correlate with each color help readers follow along. Thx
My calculations say 25.48 was my predicted best load with a 55. I bet a tenth or so higher would be the 52 load.I shot my last set of tests for TAC and the 52 grain Match Burners.

Thanks, much easier to follow. Looks like your on the right path.Ah, right.

I also like how yellow shows up. I hadn’t tried it before. I can see all the colors I have except brown. It looks like black after the alcohol treatment.
Barnes max is a bit over 26 even. I could keep pushing, but these results are more than satisfactory for a 20” chrome lined upper that isn’t free floated. I need a little TAC left to replenish my full power FMJ supply. I don’t intend to get any more of these bullets unless they just amaze me when I start shooting for score. I’ll have to switch back to the handle sights to see how that goes.My calculations say 25.48 was my predicted best load with a 55. I bet a tenth or so higher would be the 52 load.
That is the 223 load....which I find near max is best. The 556 load will be over a grain more. I havent found the additional powder useful. If one was shooting the ttsx the terminal performance would probably justify it.Barnes max is a bit over 26 even.

Your charge for the 52 makes perfect sense.... sounds like you hit a lower node with the 55 because that's my 69 load. I might be in the high node... I need to start plotting all this out.I'm pushing the 52gr SMK @ 26.2gr as I posted above. These are moving 3255 fps out of my 24" barrel. With the 55gr Hornady 55gr FMJBT I found the best load to be in the 24gr range. I have not done a lot of work up with the 55gr due to the fact that I have several 8# jugs of CFE-223 that I worked up before I got the TAC.
The yellow charge nicely overlaps the previous black charge. A pause/ flat spot so to speak, that should be a good place to load as well.Thanks, much easier to follow. Looks like you’re on the right path.
What do you color code your bullets with?The load I was using is purple, with the other shot below the paper. Orange, black, and yellow settle down considerably.
I use sharpie but I also wash the target with rubbing alcohol. Just blot it from the back at each hole and it runs enough to see.What do you color code your bullets with?
I wanted to distinguish some pistol loads and Sharpie just didn't do it; under good lighting, I could just barely see a hint of color on the target... sometimes.
Nevermind, thought you were loading 69 gr bullet but reading previous posts, you are loading 52 gr bullet.I’m getting ready to load these ... I plan to split the difference between black and yellow at 25.1 grains of TAC.
