50gr Zmax OFFICIAL Load Thread!!!

[Sgt Greybeard]

Just curious what combination of brass, primers and COL for those loads?

Just to continue this most popular thread...
I get 3300'/s and 0.5MOA from two different Rem700s with Shilen 26" bbls, using just shy of max H335 over the 50Z-Max, and with a half grain more powder I get the same velocity/accuracy from two different
Mossberg MVPs with 24" bbls. I used 50Zs over TAC for 0.25MOA once (averaged 0.35-0.5) in a 24" Stag AR, but velocity was 2970'/s.
Disclaimer: I need perfect shooting conditions to get .5MOA and specifically must deal successfully with heat mirage off the barrels. I can't see through the fog like I used to. ;>)

Another note in favor of Z-Max's; back when I was using TAC in a 20" bbl'd Rem700 I got lucky and knocked 2 Prairie Dogs off the same mound @ a measured 420yds. Given the MV of that load in that rifle, my Zs were only traveling ~1900'/s upon impact but the PDs never heard the sound. They open fast!

I've shot one MT ranch so much I often find the jackets from my Zs lying on the ground. They are spread into a dead flat flower shape. When you try to skip one off a rock (not that I TRY, mind you) they upset and the lead basically disintegrates, but the jacket spins off into the air and whines like a TV ricochet.

When you bullseye the middle of 3 PDs lined up abreast, you occasionally get a triple kill. The concussion (?) from the hit takes out the other two dogs. I've checked this phenomenon several times - mussed fur, splattered in gore, but no visible damage on the other two, yet they're stone dead.

I have a MVP thin barrel version. If you don’t mind me asking what is the loading components for the accuracy that is being described. I have W 748 and IMR 4320 on hand for my 223s

Load data we can't give out due to liability reasons, but the loads he is talking about was with our Processed LC brass, CCI and Winchester Primers, and as mentioned, a higher end load is best. They like to be pushed.

The Brass really does make a difference from what I have seen. Our Lake City Processed is very consistent and works good for everyone on our "Team" that makes these trips over to shoot PD's

Ramshot TAC, and H335 Powder. CCI and now Winchester Primers, and in our processed LC 223 brass.
That is what most of our PD team shoots
Works in every rifle all across the group

My rifle lives Lake City brass, H335 and CCI#41 primers. I've messed around with the OAL and they shoot great at 2.200 up to 2.240. I don't see posted book velocities due to a 16" barrel, but I've yet to find a bullet that's as accurate.

In your opinion, any differences between using cci and REM 7 1/2s?

Not sure why, but I've had better results in my rigs switching to REM 7 1/2s from cci 400s.

Every gun is different, and if your rifle likes them, by all means, use them.
We use what we can get in bulk and for cheap, then we work up out loads as best as possible
Winchester primers is what we are getting now, so we are using those.

CCI std small rifle primers, LC brass (dented culls Wes won't sell) and 2.230 C.O.A.L.
In another thread I mentioned I tried all seating depths from the lands down to minimum spec with so little difference I went with 2.230 because it "fits" the bullet. Almost aesthetics here.

I found AA2520 as good as H335, Varget was good, 4166 was good. But I buy H335 in felonious quantities so...

Wes I wasn’t looking for the exact powder amount more of like a starting point to work up with so I understand the liability with exact loads that could be different from rifle to rifle and shooter to shooter

Thanks for the information to all. I will check on the powder locally and of course I know where to get the brass and projectiles

Thank you buddy!! Much appreciated!!
That reply should have been a quote on my part. It was for Sgt Greybeard
All loads need to be worked up for your rifle, but start in the middle of the load range and work up from there
