I can't seat mine further by hand, but I can push them in if I put them against a hard surface.The necks are kind of thin, 0.013 in some places, maybe I just need to pick up a .265 collet to size them a little more and hopefully account for the thinner necks with a bit more tension.
They had the receiver, barrel, trigger, and just pretty much everything to do my build when I ordered except for the chassis. Still waiting on the Matrix chassis.My APR took 26 weeks to complete. According to an email I got they had a backlog on barrels.
I still don't have my rifle though. Been at the FFL since Saturday morning but they still haven't logged it in yet. Probably the last time I use this gunstore for a FFL transfer.
How much neck tension are folks generally using? My .266 collet is giving me ~ 0.002. but I've noticed that in some of my deeper seated loads, I can push the bullet down into the case by hand if I try... I guess I haven't really tried that much with other cartridges, but still it seems too easy.
The necks are kind of thin, 0.013 in some places, maybe I just need to pick up a .265 collet to size them a little more and hopefully account for the thinner necks with a bit more tension. On the other hand, the outside diameter of necks on cases where I've pushed the bullet down into the case don't seem to spring back and once the bullet is no longer seated, so it's clear the necks are yielding in plastic deformation during seating, maybe more neck tension will just result in more yielding cold work each cycle and not really more tension.
The other odd change is that the bullet grip seems to be fine on unfired cases processed the same way, I've just noticed this now that I'm starting to load some once fired cases.
My only other collet dies have been for 6.5 CM, and they've been simple and effective to set up and use.
Yepimho it’s easier to make less neck tension more consistent.
My apologies Gentlemen for the interference in your thread.

you’ve just discovered why we anneal brass.
imho it’s easier to make less neck tension more consistent. In my 260ai I only sized half the neck (using a bushing die not screwed in all the way) and only put about 1.5 thou of tension on. Worked great but after a couple firings I had to anneal or I got same symptoms as you.
on my 6.5x47 that strategy didn’t work and I really needed 2-3 thou of tension.
AMP annealer is expensive but if you’ve got the $ it beats the crap out of messing with torches and paint
So does mine in my Dasher. Kind of weird, but it kept shooting great with low ES/SD numbers so...........I don't worry about it.I can feel resistance as the bullet starts seating in the case neck, but then when i get closer to my seating depth, the resistance fairly quickly decreases and seems to drop off.
You shared information that works for you in your chosen discipline, that's not derailing a thread. We might agree, we might not, we might think it isn't relevant to the PRS discipline, we may think it is, but your entitled to your honest opinions.Sorry again guys, I just didn't wish to derail a great thread with thoughts that do not as you say align.
We used almost zero (Some did use zero) neck tension and seated about .020 into the lands shooting Benchrest. Math can prove it's easier to get consistent neck tension (smaller deviation) with light neck tension.I believe this because the lowest ES I ever get is with zero neck tension. Try it. Take some match Ammo where the neck isn’t elastic any more and reload it without resizing the neck. Where you can just use two fingers to slide the bullet back and forth. Carefully load it so the bullet doesn’t fall out.
Call hornady and Barnes and ask them. I don’t think that’s the issue at all. And if your brass has that little spring back, it again would point to the need to anneal
a "pressure ring"
Put the bullet in your quality calipers lengthwise with light pressure and see if they rotate 90 degrees and hang by the pressure ring.

No need for the passive aggressive play, and there’s certainly no reason to continually delete your posts when others don’t align with it. You offered one technique which is relatively common for a specific application, and others of us offered a different technique common for a different specific application.
