KKM 5.5" bbl. M&P C.O.R.E. 200grn. .40 VV N320 major

I searched and got tired of looking. I'm building a M&P Limited gun out of a .40 cal. Performance Center C.O.R.E. with a KKM 5.5" bbl. He wants to run a 200 grn. using VV N320. I'm looking for a starter major load for him. We started with 3.8 grns loaded at 1.160 with win sp primers and hit 749 fps. I would like some input in order to shorten trial and error. Right now we're testing with Zero's but when those run out he's switching to Bayou.

Thanks in advance.

4.3gr N320 w/ 200gr Bayou at 1.160" netted me 172PF out of a stock M&P 40 pro barrel.
