Agreed, I have a 6.5x47 Lapua and that is pretty
accurate, even with my loading skills.
6.5prc necked up to 7mm

Is that the one that Cortina tweaked
I guess so based on the notes.

Lots of chat about it on various american forums.
I’ve been using a 6.5-7 PRC, what do you want to know ?

What is the rifle and spec, who chambered it (if not yourself) and what powder and bullet combination have you found to work for you?
What’s your intended use? Mine is a F class rifle.

6.5-7PRCW reamers seem to be becoming more common. Certainly they're being built in the UK now for F class shooters, and others interested in long range shooting are having them built. A replacement for 284w with better resistance to pressure=wee bit more velocity, and brass availability, driven by F class (I think?)
Bat Machine, Brux barrel 1.8.5 T
Chambered by a friend who I won’t name.
180 or 184 Berger Hybrids
Powders that would work, or do work.
V555
VN160
VN165
RL 16 & 23
RS62
H4350, H4831sc
IMR 7828 and 7828ssc
Very accurate if you stick to sensible speeds, case capacity is the same as a 7mm Shehane and just slightly less than a R SAUM.
Brass is good and case life is reportedly very good, recoil is also non existent.

Thank you, that sounds quite the bit of kit. A friend of mine will be chambering the barrel for me, I already have it in stock and just need to get the reamer sorted and we can make a start.
PRCW, the W I believe stands for Wheeler, from Wheeler engineering. Again, I believe the only change made to the reamer is the lead angle.
If it is anything like the 6.5 PRC-W the web of the chamber area is also opened up to prevent “clickers” or the need for a small base die.
I believe you're right, I'm pretty sure Wheeler also changed the lead angle to suit the 180 Hybrid for the PRC.

What advantages over 7 saum?
Availability of brass?
The case capacity of the 7mm PRC is listed as 82gn water. I measured the 6.5PRC case capacity for both Hornady, and Lapua at 68.4gn.
Quite a difference, and the 300PRC is listed at 94.5gn. Necked down to 7mm ???

excellent cartridge
Friend has one
shoots extremely well and acheives very fruity velocities that makes the 7PRC look superfluous

I believe it's been done Stateside. When you do the maths, probably cheaper building a 33XCThe case capacity of the 7mm PRC is listed as 82gn water. I measured the 6.5PRC case capacity for both Hornady, and Lapua at 68.4gn.

Has the 7prc taken off reference sales etc from a trader POV
