What is happening is you aren’t touching the shoulders at all, but the body is being squeezed down. That’s why it’s growing. The micrometer does no good until you actually touch the shoulder first. I’d also like to point out, the variance in your fired case length suggests the brass isn’t full formed yet. Sometimes it takes 2-3 firings. Bumping back 0.002” from a case that isn’t formed is over-working your brass and creating too much headspace. ETA: I need to get one of these for my F-T/R rifle, would be handy for progressive presses. I have the mandrel for my PRC and it’s good quality.
Interesting. I know he makes high-quality stuff. I have one of his fingers. Based on the video, the process definitely did not seem any easier, and based on your previous results with other dies, I can't see you getting much more accuracy. You already shoot amazing groups, but it'll be interesting if you can squeeze even more with these dies. I look forward to seeing you shoot loaded ammo with these new dies. Thanks for the video
im glad you made this video, I was wondering about these. there is definitely a convenience factor there. im also wondering how consistent they bump the shoulder with the added joint of the micrometer top. I'm afraid it's gonna add a point for it to flex. it may take more force than most brass will require.
This in interesting. I have multiple 6.5 Grendel and 6.5 Creedmoor rifles, both bolt and semi, and I've always just bought a die for each rifle and set it up for the proper shoulder bump for that specific chamber and type of rifle. This sounds like I could use one for multiple rifles or types of rifles (I bump 3.5 thou on auto loaders and 2 thou on bolt guns)
You know honestly Rob you should upgrade to the zero press I had the same press you have and when I switched to the zero it was amazing just how robust and zero slop on anything
@@dahut3614 I have it looks really good too not sure how robust it is though I mean the zero with the locking u bolt for the turret is so freaking solid and everything on ball bearings is so smooth it's crazy
All thats happening is your not touching your shoulder yet with the die so the brass has all the room it wants to get squeezed longer but with all the squeeze, its only giving you 3 thou. 5 thou at a time is the right call.
Does the flex on your bench when you size impact quality in your opinion. During the hot Texas summer, I use the same press mounted to a Black and Decker workbench. The workbench is so light it moves up during sizing.
With my hornady dies if I take out the expander ball the brass won't work with my 21st century expander mandrel that's only 2 thou tension. Is that normal?
Which Hornady dies, bushing or non? If it's a bushing die what size bushing are you running? Are you using graphite to lube the inside of the case neck? If it's a non bushing die it's probably putting excessive neck tension on which will give you problems
I was thinking about getting this die last night as I was getting incredibly wide variance in my shoulder bump. Good to know it works once set up. I also may be changing press to the Lyman or a different turret style press. What are your experiences with it? Thanks Rob
@@jdrollason I really like the press coming from a basic lee. The turret does have some play in it but seems to be a non issue as far as consistency goes
You need to pop primers first before you start bumping back because you aren't getting a real reading because a fired primer sticks above the case and your not getting an actual measurement. Any time you use headspace guages in comparator to do bump you need to deprime your brass first. All you did was bump shoulders back way too much

I'm looking to purchase one of these dies in the near future for a 6.5 PRC. I need to build the rifle first.

Have you seen the new Nexus Press from Short Action Customs?

Zero press wont do any better

Dude your whole press is moving with every pull… 😂

"$314.00? we could almost buy our own ship for that!. We don't have to sit here and listen..."
So the sizing die can be used for any caliber that uses that SAUM brass? You only have to buy the correct bushing? Is that correct?
@@Deuceblank I’m not sure I would direct that question to cortina precision!
You need two dies? One for ID sizing, and another for base and sholder?

To correct your shoulder variance, anneal and when you size, don’t use an expanded ball. Allow a little dwell.
@@thepracticalrifleman Im using a FL bushing die. Everything was flame annealed. Not the end of the world just frustrating.
@@jdrollason using an expander ball?
@@thepracticalrifleman removed. Just had the decapping pin. Brass was all previously hand deprimed before annealing and going for a tumble.
What’s up Robert
Did someone say $314 bucks? OMG!!

No
Cortina's crap isn't worth what he charges for it
Then don’t buy it 🤷🏼. Why come crap over somebody else?
um ok . you are 100% wrong. i have most of his gear and from experience i have all works great. no issues ,
What have you bought that's not any good?
