22 K-Hornet Brass Recommendation?

[Mark M.]

You didn’t need to spell it out it was obvious. Thanks for the info on the privi brass!… where do you get this brass at I would like to try some.

To the op,
I’ve never lost a primer pocket in a hornet, always lose a neck first or signs of case head separation. I’ve never annealed my hornet brass as I don’t have that plate for my annealer although I just bought another hornet off here and may start. Losing a primer pocket can only happen with too much pressure, if your wanting speed the hornet isn’t for you, improved case is for case life mostly. I have wore out several hornet barrels and that takes a lot of shooting, always used AA 1680 , if I ran out H110 but mostly 1680 I tried them all and it’s been the best for me. I think 11.5 grains of 1680 and my cases lasts a long time. It’s a small case so for best accuracy you need to measure each load don’t throw your charges. I use small pistol primers but CCI 400 was designed for low pressure rounds like the hornet, I have better luck with pistol primers.
If your jamming to get a better formed case lower your charge to no more than middle for hornet not k hornet!… remember it’s not a k hornet until after its formed, someone mentioned making a false shoulder, I have not formed k hornet but have used a false shoulder for 6brx and dasher and like it wayyyy better than jamming, lots less pressure. Good luck and by the way Winchester has always lasted the longest for me outta win, rem or Hornaday I haven’t tried the privi but will order some tomorrow if it’s available and I can find out where.

Interesting thoughts in this thread.
The original question was basically, Im blowing out the primer pockets in three firings using Winchester Blue bag brass. Of the following choices, which brass will hold up better?

Use brass not listed and not a available
Back off the load.

No doubt PPU brass is tougher, but part of the reason for that is that it’s thicker and has less case capacity.

The powder of choice is known to spike at the top end of loads.

The fire forming load is roughly 15% over the bullet manufactures, Nosler, max load. Add that the bullet is being jammed.

A Quick Look at some issues

Swapping to PPU brass will raise the pressure, hopefully its toughness will compensate for the added pressure.

There is no need to jam the bullet or create a false shoulder to fire form the Hornet brass to K Hornet. It’s a RIMMED case. The brass is held in place by the rim. Load it in the chamber and fire it, a reduced load will help reduce splits, but it really should be in the 1% or less range.

Personally I’d ditch the Lilgun, load some mild loads of 1680 to fire form, then work up a K load using the same powder and never really worry about pressure again.

When you can find some PPU brass, re work the load.

Right now, your problem is more likely powder choice and volume than anything brass related. Other than needlessly jamming the bullet on a rimmed case.

This.

Just to back up Dellets experience and advice, I have a chart somewhere in my files (actually a graph plot) given to me by HaroldM in which he very carefully plotted the erratic nature of LilGun in the hornet. He compared the powder to many other commonly used powders in the hornet and most, if not all, showed a fairly predictable pattern of increase in velocity. However, the LG looked like a shotgun pattern. Harold is an experienced guy who carefully researched a lot of fascinating engineering over the years and is meticulous. His data told me "stay away from LG in the Hornet". Sadly, I had just loaded two years worth of K hornet (1000 rounds) using it. I find that for its purpose it is ok, but I should have used 1680. I experience early case lose due to primer pocket loosening...usually after 4-5 loadings. I am at 12 grains in my gun. So my idea of better performance and case life going K was a fail because I used the wrong powder.
That said, if you can find it, the PPU/Sellior brass is tougher, but less capacity.

@HaroldM may chime in

^^^^^this
Lilgun never would shoot in my rifle. Pressure was nuts even in safe ranges. I was about 2 full grains low before I ever got away from pressure signs. I quit a Facebook group over it as I got drug through the mud for being below min but that was the only way I didn't have a sticky bolt. Tried 1680 and all is well. I'm using Winchester currently.
