25.3 grs of Varget with 69 gr Match Kings is what shoots best in my Bushmaster AR 9" twist. This just happens to be the suggested accuracy load out of the Sierra manual also. I have killed some groundhogs with this load and I get golf ball size exits and no crawl offs.
I'm shooting the 65gr Sierra game king over 25gr of H4895 in a LC case and CCI 400 primer. My upper is the varmint model from White Oak with the 24" barrel in 1:8. Once I found this load the gun has shot 3/8", 5 shot groups with boring repeatability. I stopped there with load development and it has been a terror on big hogs down here in south Louisiana. Hope this helps.
Sorry cant help you with loads as we quit useing hollow-points of any form after a couple of seasons of video showed that be it a TNT or MK they bounce around the prairie way too much for my likeing. Just be aware of the backstop!!
