K hornet max load by way of Chronograph?
I got to try a magneto speed today at the range while running ladder loads with the 22kh.
Using 45gr speer sp pushed by lil gun. 11.1gr. 2712fps 11.2. 2962 11.3. 3028 11.4. 2998 11.5. 3019 11.6. 3061 11.7. 3038 11.8. 3062 11.9. 3108 >12.0 is unsafe Is my maxcharge basically at 11.3gr if the velocities are plateauing? I'm not finding accuracy in this range either. I need to do some development in the 10.5 to 11.0 area. Any ideas? |

Are you sure that you’re not seating into the lands? (I know but I had to ask) You must have a fast lot of lilgun. 12.0 is a starting load and 13.2 is max.

And what brand brass are you using? Regular 22 Hornet brass capacity can vary over 1 full grain of powder, depending on brand.

Lilgun can vary lot to lot quite a bit. I use it in a straight Hornet, but also have heard it can be peaky in a KHornet, but no firsthand knowledge. My Remington cases hold about a grain more than WW, and Privi holds a touch less than a WW.

That’s odd I’ve run up to 14.0 gr of lil gun with the 40gr Speer and Sierra slugs and the Barnes 45’s without a hint of pressure signs in my straight hornet. But I’ve settled on 13.0 for accuracy. I haven’t noticed any significant lot to lot variations either. Is this a tight match chamber? What brand brass are you running? What type primers?

What type of primer is being used? In my experience it makes a big difference when using Lilgun in the K Hornet.

+1 I've had best results with pistol primers like CCI500.

I've used WW and RP cases. I find RWS cases to be the heaviest, with lowest capacity. WW cases hold almost a full grain less than RP cases.
I size only 3/16" of the neck, virtually nothing on the case body and I use a Lee Factory crimp die (.218Bee) for both Hornet and Bee cases. My SD's are under 19fps for the hornet and 12/13fps for the .218Bee. One rifle had would permit only pistol primers for best accuracy, while the other has no preference. I seated only enough bullet in the case to crimp and hold it there securely, thus why I did not size more than enough case to hold the bullet. In RP brass, I went up to 13.8gr. LG with 45gr. Hornady & 40gr. Barnes X bullets and up to 14.4gr. with 40gr.HP's, Vmax and BallisticTips. I used 13.5gr. with 50gr. Hornady SP's. My 1st season with loads of 13.0gr. LG with 40gr. Vmaxes ran 3,200fps. SEcond and subsequent seasons saw 14.4gr. LG for 3,340fps with Hp's and Vmaxes and 3.357fgps with the Nosler ball. tips. I fired my original RP brass 14 times then turned them into .17AH's - with NEVER annealing them - RP brass rules - (in this ctg.) After Fireforming to .17AH, they started splitting necks on the 3rd loading, so I HAD to anneal at that time. In WW brass I went up to 13.5gr., but settled back on 13.0gr. as that left more room in the case & still gave me almost 3,200fps. Here are 2 cases, sized and primed. The left hand case is a WW case, with plated RP on the right.The plated cases have almost 1/2gr. less capacity than the brass RP cases. There is 13.0gr. LG in the WW case and 14.0gr. LG in the RP case. I've gone through quite a few pounds of LG since 2002 or 2003 in my Hornet and .218Bee, and have never seen much if any difference lot to lot. Perhaps I was just lucky?? I've never seen any pressure excursions nor what I would consider high pressures. It has been a marvelously accurate and clean burning powder for me. In light loads, I did find it produced dirty case mouths, but not after getting the pressures up where it performed. I have heard of some guys having pressure problems with Hodgon's loads in the "K" version.

Lil Gun didn't deliver accuracy in my 22 KH either, and I tried several brands of standard small pistol primers as well as Remington 5 1/2 and 6 1/2 and CCI 550.
13.6 gr. of LG with a 46 gr. Winchester HP did deliver a stunning 3284 fps. I settled on 12.9 gr. of 296 with a 40 gr. Nosler Varmintegon or Hornady V-Max with delivers 3123 fps and 1/2 MOA accuracy. |
