What kind of luck are you guys having reloading for the 7 PRC? What powder and bullets are you guys having the best luck with and what velocities are you getting? I am running a 26” barrel with a suppressor and I’m seeing 2850 with 1 moa in accuracy with factory Hornady 175 ELD-Xs.

7mm PRC
Anyone loading lighter projectiles for deer? 175 gr seems a bit heavy. Thinking more in the 139-147 range? Trying to justify using my new rifle for deer season this Fall. I noticed that Hornady has published 7PRC load data for a 139gr CX.

Just for clarity, are you indirectly saying you think this is good or bad, so you want to study alternatives to improve?
Speed or target performance, or both?
Just for perspective, your 175 @ 2850 is giving you 4280 Joules or 3157 ft*lbs
To get this to 3000 fps you would need an additional 341 ft*lbs worth of energy, which is like adding the equivalent of a 9mm to the load.
There was lots of hype and marketing when the 7 PRC was released, and after a while there were many folks who thought they should get higher speeds with their 180s too.
If your rig is getting 2850 and an honest 1 MOA, that is better than the average that I have seen. Not telling you to settle, but for perspective many folks in marketing are known to say things that they know are not true.
To get this up to speed (62KSI) you will need to increase the charge with handloads, or find some of the factory loads where they already did this. There was some ammo at first that was fast and later some that was slower, and recently it is getting faster again. YMMV
