Quik load guru’s ?

Can someone that knows Quik load check the pressure on this load? 20” 223 Wylde 1:7 twist.

It's thermonuclear.

All kidding aside, QL for some reason or another doesn't model XBR close to being correct. In QL it shows to be around 76k PSI. It's not.

24Gr XBR is the exact load me and a couple of other friends shoot with 77gr SMK and TMKs. We have shot this load to 1100 yards before and have used this same exact load in at least 10 MK12s. It's a high load for sure, some people have better luck in the 23.4-23.8 area with that combo.

Generic GRT inputs puts it at 64 and some change PSI & 2850 mv.

Thanks, I’ll look into downloading that program.

I ran GRT for the 77 TMK - I haven't held them side by side but there's several K of PSI difference between what Heretic got with the SMK, for what it's worth.
