I have had a love hate relationship with a 22 k hornet by cooper for a year or so now. It has a slight head space problem. When forming cases the primer back out a little. I have to use a groved shell plate for the first loading. I have never been able to repeat the test target , with lil gun the only powder I have tried reloading with. I have had trouble getting it to shoot moa on some days when my 17 hmr was shooting 1/2 moa. It it would show some potential on one outing and the next outing shoot 2 moa. I loaded 10 rounds with vv n 110 - 10 grs and a 40 gr v-max. 5 shot through one hole after sight in at 50 yards. it was blowing to hard to test at 100 yards. The bolt was sticky on a couple of rounds, it may have been the cases. I am going to form some new cases. I need a load for the standard hornet and the k hornet with vv-n110.

Try some AA 1680 or Win 680 if you have any. I would also only partially size those cases to hopefully get away from the rim diameter vs the head to shoulder issue you are experiencing. Just enough to grip the bullet. Good luck.  Member NRA, SCI- Life #358 28+ years now! DRSS, double owner-shooter since 1983, O/U .30-06 Browning Continental set. | |||

I am working the necks only so that it headspaces on the shoulder only. I have some a1680 Pm me some load data if you can, Thanks JD DRSS 9.3X74 tika 512 9.3X74 SXS Merkel 140 in 470 Nitro | |||

I will see if I can find any of the old loads... Member NRA, SCI- Life #358 28+ years now! DRSS, double owner-shooter since 1983, O/U .30-06 Browning Continental set. | |||

JD, I loaded some virgin brass with 9.4 grains of N110 and some 30 grain VMaxs (YES you read it right 30 grain VMaxs!!)(( the bullet loaded in the newest Hornady 22 Magnum loading)) that Midway sold in one of their "blemished bullet sales" and I wish I could find another big batch of them to load!! Shooting in a Ruger 77 Target Gray heavy barrel they were turning out 2780fps but were absolutely "stacking them one on top of the other!!" I shot some 35 VMAXS last week ahead of 10.0 grains of N110 and not the same accuracy as those little 30's, it gave 2800fps and a little less than 1" at 100 yards. Mild, decently accurate and sure don't cost much to feed!!! GHD Groundhog Devastation(GHD) | |||

I have a CZ 527 sporter in 22 Hornet and the best powder (for my rifle) has been WW296. With the Hornady A-Max my best repeatable groups has be 3/8 inch. I've very pleased with this rifle. | |||

308Sako's advice is sound. I've found AA 1680 to be the most consistent powder in both the Hornet and K-Hornet, and it's difficult to reach overpressures with it, at least as long as you keep your bullets on the light side. You're doin' right by you K-Hornet to headspace on the shoulder -- the rims of Hornet brass vary so much from brand to brand that I find it impossible to rely on rim headspacing, other than being forced to rely on it for the first shot. I suppose you could try seating the bullets out to jam into the lands, but with the thin/weak neck on the Hornet brass I'm not sure that the firing pin force wouldn't push the shell forward against the rim, anyway. As far as loads with AA-1680, it is nearly impossible to get enough into the case with 40 grain or lighter bullets to create excessive pressures. Just measure out whatever makes a reasonably full case with your K- brass (probably about 14 grains) and load a 40 grainer atop it. I believe that WW 680 is the same spec powder, but not having worked with any of it I'm going to refrain from comment. By the way, the "high" Hornet velocities people report with Lil Gun occur, but are illusory: Some individual shots are very high, while other shots in a string register 250 fps slower. So, I've found Lil Gun to simultaneously yield both the fastest and slowest velocities  My experience with Lil Gun in very heavy magnum hand gun loads is just the opposite where it exhibits very consistent performance. | |||

I tried a lb of little gun ,it looked like it might shoot well so I bought 8 lbs to use in the hornet and my 300 acc black out. From the story's I am hearing about presure spikes I will not use it for either. In the hornet it produce terrible vertical string in my rifle.

In my experience all the VihtaVuori powders are excellent and consistent. In my 1926 German single shot, now a .22 K-Hornet, I use 10.0 grains with the Speer Spire Point. This shoots inside an inch if I use the set trigger properly. | |||

Left at home the copybook where I trace the load data and the range results. Until now my 22 K-hornet Anschutz,with 45 grs sierra bullett, Remington case and Federal GM primers made the best groups with IMR 4198, then here is the Hogdon 4198, then VV N120 and then the VV N110. Tomorrow I'll try to make you have all the data. Yesterday at 100 meters shooting on a square inch orange mini target glued on a normal target I had 4 shots in a hole and the fifth in the left low angle of the orange target. I'll try to pst photo too bye Stefano Waidmannsheil | |||

  As I wrote yesterday: the above groups has been done with VV N110, 9 grains, but probably I'll increase the load. Here below two other groups made with 11,6 grains of IMR4198   and one with 10,4 grains of H110  rifle Anschutz mod.1432 bye Stefano Waidmannsheil | |||

The trick with Lil'Gun in the hornet is to use enough of it to produce consistent burn together with a heavy enough bullet. Compress that powder! Be careful with Lil'Gun in the k-hornet. The books show higher pressure than with the standard hornet. FWIW I get 2740 fps with 55gr bullets with Lil'Gun. I do seat the bullets in a 'paper/grease cup' and head-space on the rim with unsized cases. That's with R-P cases. One day a range pick up Winchester case got in the mix and it loosened the primer pocket. I don't think it's possible to get that performance with the K-hornet. Case shape and/or volume? I don't know. Lil'Gun is weird stuff. Regards 303Guy | |||
