7-6.5PRCW

[Willow]

The BC die is speced smaller than the virgin case head. You cant go smaller. You may want to measure your die to see if its out of spec.

I'll have to check with my gunsmith on measuring the die but across the 30 cases I fired last weekend, they're all resizing to 0.5320 at the .200 line as best as I can measure.

6.5prc sizing die dimensions/clickers

I am starting to get clickers with my 7-6.5 PRC brass. I have my reamer spec at .535" to add extra clearance at the .200" line to prevent clickers. Fired brass measures .5342" at the pressure ring. Sized brass measures .5332" at pressure ring. I believe my sizing die is not sizing enough...

Maybe the SAC dies sounds promising?

Erik did a video on his new sizing die. In the video he says his die will work with the .532 or .535 chamber. At one point he shows the sized case out of his die it measures .531 after sizing. Dimensions listed @.200 line

Erik may have tested this I dont know. But I would be surprised if it would work with the .533 but it would great if it did.

About 4:40 is where he says it will work with both chambers

Is the no turn reamer just as easy as necking up the brass and hit the ground running or will a skim turn be required? If so how is the brass holding up, read some people report a “donut” in the neck? What’s a loaded round coal with 180-190gr, possible to mag feed in a short action?

Thanks in advance, looking to build a hunting rig and this seems to kick saum and sst to the curb in brass choices/availability alone.

I use a no turn reamer for my 7 PRCW and have no issues with accuracy on target.
Shot a clean last time out...so it will shoot. The shooter is another story altogether..lol
As far as Mag lenght you will have a donnut to deal with as you will anytime you neck up brass
from my experience...I just seat above the donnut and no worries. You could get a inside neck reamer.?

I've not encountered the donut as when I neck turn, I also cut into the shoulder which has prevented the donuts from forming - for now.

Y’all pretty much answered the question I was looking for. I’ve only necked down and fireformed so I’ve never encountered a donut. Thanks.

When I turned necks with the 6.5-284 Lapua Brass and sized up to 7 for my Shehane I still found the donut after a few firings ..so good on you Willow for avoiding the pesky entity altogether.
After that I tested with Turned and No turn and found no difference on target as far as my shooting goes..YMMV however.

In a no-turn chamber, the donut will get you sooner or later. I've been shooting some form of this cartridge for about a year and a half now (across 7 barrels) and because the brass is a bit thicker your will definitely get the donuts, it's how you address them that matters. As an example, in my improved chamber, the donuts got big enough on about the 8 to 10th firing that when I ran the mandrel in the necks, enough material was being pushed out that it was actually affecting my ability to chamber a loaded round (even though I was loading above the donut). This can ultimately be addressed by either A) only running your mandrel 80% of the way into the neck so the donut isn't pushed out B) using an inside neck reamer to cut the donuts out, C) pushing your shoulders back a bit further than normal but this comes with other potential risks or D) neck turning the brass either before they appear or pushing them out and turning them off.

I can say that because it's magnum brass, the donuts are more aggressive in this chamber than when I used to neck up 6.5x284 to 284win. No matter what, you can't neck up from 6.5 to 7 without donuts appearing at some point, so you need to have a plan on how you're going to handle them when they show up.

Any tips on clickers? What die are you using the size down the .200 line?

First thing is that once you have clickers, it's pretty tough to get rid of them completely, especially with Lapua brass because it's pretty beefy. But starting with virgin brass I'm using Cortina's sizing die. In a standard press it works great but I have found that with my auto drive on a 750 it helps to 'pre-size' the base with Cortina's mandrel die minus the mandrel to knock the base down before hitting it with the full length sizing die. His mandrel die is base sized to match his sizing die so it's a great combo and I get zero clickers now.

I sent JGS a sample round loaded with a 180 hybrid at 2.935" OAL to have a reamer made. Going to get it ordered in the next couple days. My purpose is the same as yours, mag length short action. The print they sent back after measuring my round has a .000 freebore VS the .220 used on Mr. Wheelers print. I'm definitely curious of the OAL of the guys shooting 180 hybrids with the longer throats to compare.

My 180 hybrids measure 3.125 aprox overal lenght. I have a .240 freebore
Shooting F-open and single feed only.

I think for my purposes I’m going to stick with 7saum or 7ss. I really hate to add more steps to my case prep. I was really hoping this would be a better cheaper route. I would however like to know how this works out for you.

Are you jumping them? Thinking my 0 freebore may be way too short.

I'm going to use the 7-6.5 for a hunting rifle as well as an f-open gun. Same brass, bullet, primer, hopefully powder, dies will simplify things a little bit.

The donut is what scared me away, I don’t neck turn/ream now and I’d rather not start but I’m also not a benchrest or f class shooter.

180s at 2.950 aren’t touching my .045” freebore.
