Might have to dip into my last pound of XBR for 10 or 20 rounds. The weather is the only thing that can wreck us.

Got these 75s loaded up to test this weekend. Running the RMR 69s and 75s with WOLF SRMs, H322, and Norma once fired brass.
Here's pic of the Hornady 75gr, RMR 75gr, and the RMR 69gr

Those look more like Sierras in the Ogive than Hornadys. I wonder if they’ll be more forgiving to jump length.

OAL with no dies adjustment was about .005" longer on the 75s compared to the 69s.Originally Posted by 1168

What load are you using for the 75’s?
Senior Member
21.8 gr of H322. Same load I use for 77s. We didn't chrono or shoot any to 1000 yards yet. We had a pair of extra shooter yesterday, and I didn't feel like setting up the chrono. Next weekend probably.

Did you end up doing this? I have a some XBR so curious to hear the accuracy with that combo.

Also, we didn't do any load development. Just subbed in the current load so we should be able to get these groups to tighten should we choose to work at it. If we can get MOA consistency, thats good enough for us. Just had some weird fliers Saturday.

I did. Shot 5 on paper which were similar to the other groups. I really should have got chrono on them, but I've given up on getting every single thing buttoned up on one range trip. We'll get some more info this weekend.

I’m out of 77gr SMK and perilously low on 77gr Nosler bullets. Based on the fun you guys are having I may order a thousand of these new RMR 75gr.
I’m curious about the terminal performance since the “H” in 3GH is allegedly for “hunting”.
