Was talking about this round today, glad I stumbled onto the thread. I’d be interested in a reamer print too or the name of the company who has it. Thanks for the info!
7-300 PRC Initial Results - Winner

Like Graham said reamer print is based off what bullet you want to run and jump. Most reamer makers dont make available personal reamer prints that people have requested but they may have created one of their own for the public. I'd call jgs and ask or like Graham said sent in a dummy round.
It's been running well. I dont know what's coming from hornady but when I spoke with them they said if they did a 7prc they would probably change the case dimensions a bit from the 300prc. I'm guessing they will be releasing 6GT brass that George already is selling.
Yup, I think the 6gt is a given. But if there were a 7 PRC that was aimed at the 28 nosler that would be awesome. Even if it were taking on the 6.5prc case/dimentions to compete with the 7 SAUM I'd be a happy camper!
I've seen somewhere you can use 8x68 RWS brass and form it for use as a 300 PRC.
Because Hornady brass is shit.
Wow, I had just started trying to work on this wildcat. In 2009 I had started a .30-375 Ruger, crazy exwife, divorce came, sold it all, blahhh, now it's the .300 PRC. So then I get an idea to try to make a .284 lol Let me say, I admire what you did, and the performance is even better than I had expected.
A great friend of mine, who is a PH in South Africa, just told me this very thing.
Yes. Hoping for Laupa, Starline or Peterson to get on board soon. Till then....ugh.
300 PRC brass from ADG is on preorder now and slated for January 2020.
Any updates on this round?
7mm is my all-time favorite round. Would love a 7mmPRC

I'm not sure your definition of easily obtainable. There are a number of gunsmiths clambering them up now but if you mean a factory offering it will probably be a bit on that if at all.
I was really hoping Hornady would have released a 7 prc based off this 300 case at shot this year. Hopefully they will Sammi spec it someday soon. My Kingdom for a decent 7...
If you need to move from "decent" 7 to Ultimate Super 7mm overmatch round, @THEIS has some new Hoplite brand rifles coming out hopefully this year and he has several super 7mm versions. Just think what you could do with a 7mm round pushed to somewhere close to 90k PSI or greater....
With the performance of his 7 MAX cartridge I’m not sure I’d bother with the 7-300PRC

I have a barrel at the smith as I type, that is being chambered in the 7 Sherman Max. It's ideal I believe.
I'll be curious to hear what the 7mm S Max does?
I was all set to do a 300 Sherman till I heard he had the 280 in the works. It sounds very promising.
Flounder's results are good so the Sherman 280 should be very good with the improved case.
As soon as he gets reamers in I'll be sending one to LRI
Rich told me the ADG head stamped 280 Brass will need to be loaded and fire formed to blow shoulders out to 40.

Just got some of the 30 Sherman brass and it’s standard PRC shape right now. Need to blow the shoulder forward.
I have a 7SS as well and now want one of 28 Sherman’s but a 215 Berger hybrid at 3100 FPS is hard to beat and both should be very close in the real world. If I was starting from the beginning the new 28 Sherman seems to be the best of both worlds.
He just shot the 215s at 3300 with RL33 on 6x brass no pressure or loose pockets
And that's only a 28" barrel
Laugh.out.loud.
Lol
Excellent accuracy, Jump tolerance and an excellent BC for the 180 grain bullets but can be frustrating watching that trace disappear well before the target and you scratching you head what happened.
With the ELD’s ?
1930 yards.
I quit using them because I was getting more than 25% blowing up before the target.
190 long range hybrids and 190 A tips.
I haven’t decided which one I’ll buy in bulk yet.
How does the potential mv compare with the 7-338 and 7-338ai with the heavy 190-195gr 7mm? I was looking to go that route for a while.
Jesus
The flatness of that with A tips would be amazing while it lasted.
well if a 30 sherman does 215s at 3200 I can only imagine what a 190 does
hell even if it only gets 3200
Contemplating 7-300 PRC versus 7 LRM. I’ve tried to read on these, but I’m a bit jumbled. Things I think I understand. 7 LRM is a necked down 375 Ruger. 300PRC is derived from 375 Ruger and therefore 7-300 PRC would be a second derivative of 375 Ruger. What are the differences in 7-300 PRC and 7 LRM? Shoulder? Neck?? Any real world performance advantages? Brass for 7 LRM isn’t as ”good” as 300PRC from what I gather?
7LRM is about .15 shorter in body length so less capacity than the 7/300PRC
You should also look I the 7MAX.
I did some reading on the 7MAX and reviewed some things on it. I might do one in XM action if XLR makes their Element magnesium chassis in that length at some point.
Sounds like a 7-300 PRC for me now. I was planning a Defiance AnTi action, with 26” Bartlein CFW #4 in a XLR Element magnesium with TR2 buttstock. Javelin Bipod (or hopefully Valhalla if it’s out) and topped with a S&B to round out the package. Should make a fun LR hunter.
Ultralight hunter will be 7 SAUM or 7MAX in XLR magnesium (one day if XLR is listening....) XM length with carbon buttstock. AnTi (or maybe Ti action) and Bartlein barrel at 24”. Have an extra S&B 5-20 US waiting for that build. Should be able to stay 8ish pounds. That’ll be my mountain gun for sheep hunting!
