What hand load comes close to duplicating factory Hornady 123gr SST

[kbarnes12]

I have 16" and 20" Grendel rifles that I have tried to develop a hand load for a 100gr Barnes TTSX, but I have not found a recipe for that bullet that comes even close in accuracy as a factory Hornady 123gr SST.

So my question is, do any of you have a hand load recipe that comes close to duplicating the ballistics and accuracy of the factory Hornady 123gr SST?

Have you tried 30.0gr of XBR under the 100gr TTSX?

I loaded 50 Barnes 100 grain TTSX with 29.0 grains of H-335 with CCI 450 primers in Hornady cases. The few I shot at 100 yards were close to 1" 5 shot groups. This is not a hot load but shot so well I never looked any further, this might be a place to start.

For 120-125 grain bullets I'm using CFE 223, this powder with CCI 450 primers gives the best accuracy and velocity in my 16" & 20" 6.5 Grendels.
