115 gn RN FMJ over 6.5 grns of Win 231.
Wow! 6.5 gr of W231 is way over pressure for 115 gr FMJ!
Winchester load data lists 4.9 gr as max charge for 115 gr FMJ -

I'm currently using Precision Delta. I want to try something different as it's time to reorder. I'm looking at two that I think may be better projectiles than PD.
Berry's 115gn FMJ RN or Hornady's 115gn XTP
It will be used for training and practice only.
As far as I know, Berry's MFG only produces plated bullets for 9mm 115 gr. Over the decades, I have used Winchester 115 gr FMJ as my reference 9mm bullet but have shot various other FMJ/JHP and regular/thicker plated bullets.
I believe Atlanta Arms used or currently uses Zero FMJ bullets for some of their match grade ammunition (115 gr FMJ loaded to 1.130" OAL) which produce 1.5" groups at 50 yards with match grade barrel fixture -

For the "Myth busting plated bullet" thread, I have started initial comparison testing with jacketed bullets using Hornady 115 gr HAP (essentially XTP without the expansion cuts on nose tip), Zero 115 gr FMJ and RMR 115 gr FMJ using W231/HP-38 -

I plan to conduct further testing once the rain season ends (we got like twice the average rain fall this winter) but the initial testing results were eye opening. I consider Hornady HAP to be very accurate bullets and many reported great accuracy with Zero bullets but my initial shot groups showed comparable if not smaller shot groups with RMR 115 gr FMJ bullets (Testing done with scoped 17" Just Right carbine with bipod at 25 yards shot prone).
If you are looking at training and practice (and even for match shooting), I would seriously consider RMR 115 gr FMJ bullets they manufacture themselves and test RMR 115 gr Hardcore Match plated bullets for accuracy comparison -

With RMR 100 gr Hardcore Match RN and JR carbine, I got sub 2" shot groups at 50 yards -

BTW, nice picture of 115 gr FMJ for your avatar. They are Winchester 115 gr FMJ loaded to 1.135" -
