In the ammo we've received and the load data provided to us prior to the launch of the 7PRC, the powder Hornady used was RL26.I believe that Hornady has been using Staball HD for their factory loads. I picked up 8lbs of it and found similar mv as their factory stuff but it’s hard to know for sure as I’m still breaking in my barrel and I have a 27.5” barrel. I’ve got 16lbs of N570 as well and was going to try the 190 atips and Bergers, as well as the 195 Bergers but not in 7mm PRC. The F Class guys are shooting N555 (and H4350 to H4831SC) with the 180s but not in 7mm PRC but rather in a necked up 6.5 PRC like an Alex Wheeler case 7PRCW in Lapua brass.
I see no mention of N568 ? Reason s ?. Thxs
Excellent, thanks for sharing.I am using N570 in my 7mm PRC with 180gn VLD-H out of a 26" PVA 8 twist prefit for a Sako TRG-S. My current load is 70.5gn and my Magnetospeed is reading 3020fps. I have shot it out to 1270yrds. The ES is what has me hooked. I have had 5 shots with an ES of 13fps. I harvested my spring black bear with it on Tuesday evening.
Thank you for the replies. Especially the quick load data.
I've gone through longrangeonly and hawkins "guides" I'm not sure why they are referenced now when N570 is not mentioned. Backfire tv also has a "guide". Ive gone through these 3 guides and typed up the information in a more usable format for me but again, N570 is not mentioned.
I will load up some 184 Berger hybrid and run them in front of the chronograph to get some data hopefully in the next week or so.
Looks like a update came out in AprilWhat version of QL are you running? I need to get the update I guess, mine does not have 7mm PRC.
This tracks with the 6.5 and 300 PRC as VV570 is usually listed as the fastest potential for them using heaviest for caliber bullets and similar compressed loads. My 6.5 CM is magic with that same compression level using RL26.
That looks more like what I would expect from a case with much capacity and a long throat.7 PRC
26-inch, 1:8 twist barrel
195 gr Berger
66.9 gr N570

I know the cartridge has not been officially announced but a few forum members are playing with the cartridge using RCC brass. I would prefer you guys keeping your testing in your personal threads but you can post proven loads here. Please include all the data you can and group pics if you have...www.longrangeonly.com
I’ve seen pictures of Adg 7prc brass but I haven’t gotten notifications for any being in stock anywhere. I’m sure some of the YouTuber’s have their hands on it but I haven’t seen any videos released yetI haven’t seen any test work with Peterson or other brass.
