Can anyone share their load data using 69gr SMKHP's and 8208 XBR powder? TIA.

I loaded up some Sierra 69gr TMKs with Tula primers and tested up to 24gr XBR 8208 for pressure signs. I backed the load to 23.7gr and it shot well for me.
I found out first hand that XBR, like many powders, is lot sensitive. We had a hot load that a buddy worked up. And it was working nicely until I bought a different lot of XBR. I got a lot of blown primers after the lot change.

Good to know. I have loaded up 10 rounds starting at 23.1grs (increasing in .3gr increments) up to 24grs max. Brass is once fired Hornady with Fed 205M primers. I hope to get out and do a little shooting next week. FWIW, the barrel is a 20" Krieger 1/7.7 twist.
I've gone up to 24.0 using 69s with good results but I chronograph every time I get a new keg and adjust the charge.
Pappabear grabbed an 8 of XBR. I'll have to dig into it and compare velocities on this stuff. As mentioned up above, the last two times I checked, the changes were stunning.
