Advice? Which of these 2 loads to pursue?

[Mike_Honcho]

Ramshot TAC / 175 SMK / 4x Lapua / Win LR Primer / AIAW 24" / THOR Ti

A) 5 shot groups - so small sample size / minimal statistical significance
B) 42.2 group has least stringing (image upside down - bottom group 2,603 av/ 15 ES / 6.52 SD)
C) 42.8 group - top round was on me but the high shot was definitely stringing (image upside down - mid group 2,658 av/ 5 ES / 2.74 SD)
D) Other group was 43.2 and 2,770 av with 137 ES (did not calc the SD) all holds were money - so this load just walks around

Short of loading up 10 or 20 more of each of the 42.2 and 42.8 and testing it at 100 - 300 - which would you pursue?

Hint - my old RE15 load (2,609 av, 31 ES, 13.45 SD) was an easy 1/2 MOA load at 100 and I have had lot and lots of hits out to 1,150 with it. I would rather be out banging steel than dinking around with that last tiny bit of potential accuracy.


Thank you

My standard TAC load was 42.5grs. So you're right in there.

I'd run some at each and one step in between them 10 shots of each charge to make sure you find the sweet spot in it. Then double check another set of 10 of each at 300. It's a lot of ammo for a test but if you really want to dial into the best charge for that combo it's probably the best way to see it. You're definitely closing in on it though.

You answered your own question. There is near-zero significance to your data. You need to shoot more.
