Tikka .223 Wylde/80 ELD X Seating Depth…Wow…

I think 8-10% increase in powder capacity is right in line with reality. So yes, I think you could fit 28 grs

Looking back at my reloading book for the 80's, going from 25.0 to 26.0 was a change of 100 fps with N150.
Seeing how I'm currently at 2800 fps with 26.0, 3,000 fps from bumping up 2.0g seems within the realm of possibility.

It’s really nuts when you think about it! Really brings it to life!

Just got off the phone with Shell Tech about the NAS3 5.56 cases. It shows back order, but from what he told me, cases are coming in, so orders should ship pretty quick.

He was a nice guy, and took a few minutes to answer my questions. Figured I’d pass it on here.

Reloadability: Cases are not reloadable at the moment, but he will be bringing out the sizing die at some point, and then they will be reloadable. He said it may be the end of the year before he gets around to designing it and bringing it out. With this being the case, I’d hang onto my fired cases.

Finding pressure: According to him, the case heads will handle up to 250,000 psi, so they don’t show pressure. They won’t blow primers. The sign of too much pressure is when you’re piercing primers. This happens somewhere between 80k and 100k psi. Obviously, we know that some primers have weaker cups than others, so do with that what you will.

Neck lube: I asked about the possibility of needing to use neck lube on new cases. He said this is not necessary. Just prime, charge, and seat bullets in new cases and go.

Neck crimp: Using a Lee FCD is mentioned on their site. He said this is not really necessary. With the stainless, you can cause a super high bullet pull pressure if you do this. It’s also semi difficult to get a perfectly symmetrical crimp, and because of that it can reduce accuracy.

Increased case capacity: 5.56 cases will have 8-10% increased case capacity over standard brass, with larger cases being up to 12%. Because of this, velocity and pressure will be lower if you bring over your existing load from brass cases. If you’re using a slow powder for your cartridge and bullet combo, you may find an advantage by switching to a slightly faster burning powder to hit pressure and case fill at the optimal points.

Hope y’all find this information helpful!

Appreciate you taking the time to share your findings. What a time to be alive in the ammo and reloading world

Finally received my backordered NAS3 cases from Shell Tech on Thursday. They are definitely light! One thing I noticed on them is since the case head is a separate piece, it appears (I’ll have to double check it) that they might use the extra material from the flash hole as a type of crimp to help attach the case head. The flash hole has a rounded edge, and is on the larger than typical. It also appears extremely uniform. Probably not benefits that we’ll see on target, but kinda cool nonetheless.

My buddy is coming in for a few days next month, and we’re gonna be working on load dev for two of his rifles. One of which is a 16” Tikka 223. I’ll be trying the cases out in his, as well as my 18” Tikka 223. I’ve got 77 TMK, 75 ELD, 88 TMK to try.

Mine are scheduled to arrive Monday. I’ll have data to share within a day or two with 88 TMK’s as well.
