loads with hodgdon H110? anyone?

[Skrenos]

I'm trying to make some loads with 7.62x25 and 10mm. I would like to use H110. It works great in my .357 mag http://www.ak-47.net/akcgi/smile.gif

For 7.62x25, I'm using starline brass with CCI small pistol magnum primers. For bullets I'm using .308 90 grain XTP hollowpoints.

I can maybe for 15 grains of h110 in a tokarev case. I feel safer using h110 because a 1 grain difference isnt going to blow your gun (i've done it).

the hodgdon manual lists 17.5 grains for a 85 grain bullet...so I'm guessing 17 grains for a 90 grainer. that'll give around 2300 fps from a 20" barrel.

ok, did my testing for 30 tok. I used CCI SPM primers, once fired S&B cases (didnt want to mess up my starline cases yet), and 90 gr XTP bullets, just in case you havent been following the story.

Anyways, I loaded up 14 rounds, starting at 10 grains and incrasing in powder weight to 16.5 of Hodgdon H110.

10.0= Report was unlike anything I've shot from a cz52. It was a deep GrrrrOOWWW!!! sound. It sounded mean and cool http://www.ak-47.net/akcgi/smile.gif tossed the brass around 2-3 feet from me. Large muzzle flash, on par with S&B concering the flash.
10.5= did the same thing as 10.0, but tossed it around 4 feet. I just now noticed the cases are blackened around the mouth, probably very weak loads carbonb burning the outsides...
11.0=This small jump made it very potent. Tossed the brass around 20-25 feet from me.
11.5=ditto
12.0=THis load is pretty on par with S&B concering tossing the brass (30 feet), and recoil. THe muzzle flash rivals my 16" SKS.
12.5=ditto
13.0= HUGE fuckin' flash! http://www.ak-47.net/akcgi/smile.gif about the size of a fully inflated plastic grocery bag. tossed brass around 25 feet.
13.5=less dramatic and tossed brass 30 feet.
14.0=large flash
14.5=lost the brass but flash was same.
15.0=tossed 55 feet. Very potent. Would probably equal 30 carbine if fired from a pistol. (hodgdon lists 14.5 grains with 100 grain bullets in 30 carbine) This is the load I'm going to use from now on as it's very potent and it doesnt damage the brass.
15.5=case mouth dented. Heavy crystalized (case stretch)
16.0=It went into low orbit, cant find it. http://www.ak-47.net/akcgi/smile.gif
16.5=Less of a case mouth dent than 15.5, tossed the brass further than 15.5. Case was not crystalized from stretching.

Well, inconclusion, I suggest 12 grains for S&B replica ammo in tokarev pistols, but 15 grains in CZ52 pistol. I'm going to load up a batch of 48 rounds, and video tape them tommorow or next weekend to show you guys the muzzle flash on this bitch.

I didnt notice any damage to my barrel or any lodged bullets or severely damaged brass. I maxxed out at 15 grains. I could go higher and use it safely, but I dont want my case mouths to be dented inwards. Even though this ammo is louder than S&B or Norinco, it is on a lower octave than either, so for hearing damage it might be equal or less than commercial ammos.

I could not test ammo functioning in this test (I will during my taping), but even the 10.0 or 10.5 ammo might cycle your gun. the 11.0 definately will and is the lowest you should go for guaranteed functioning. I tested my ammo by loading one round from magazine, removing magazine, and firing from offhand. I was wearing a leather jacket, glasses, foam earplugs, and military leather dress gloves....just in case my ammo or gun gave way.

WHen I get my 10mm conversion kit for my witness, I'll load some 10mm and give you guys the results for that.

Damn, Skrenos! And I thought I was being a badass when I did my own handloads for my CZ-52 about 5 years ago. I got about a 1900 fps bullet from mine. And boy, did it feel RIGHT coming out the barrel, as opposed to the Chicom 7.62x25 crap for the wussie Tokarav. My CZ, I swear to God, almost felt like it was trying to talk to me - I swear I think it said "Thank you" for putting the GOOD stuff through it!

[Skrenos]

Yeah. The Norinco ammo will not let the slide fully close. I have to bring my thumb up and push the slide closed. it's real easy, but the slide is still open. Man, I wish I could get a chronograph http://www.ak-47.net/akcgi/smile.gif

H110 is famous for big muzzle flash, especially with lighter bullets and mild loads.
If I may suggest, contact Accurate Arms and get their load data for CZ's, it's not in their manual yet but they will send it to you free. With AA-9, they get 1900+ fps out of a 5 inch test barrel.
Also, I would be EXTREMELY CAREFUL using .311" bullets, the factory bullets are .308". If you have a tight throat area, you are risking a KA-BOOM. It could explain why your slide needs a push to chamber. The Sierra manual is very explicit about not using .311" bullets without reaming the case necks, can cause dangerously high pressures.
Try the Sierra .308" 85 gr soft nose, it is designed just for the 7.62X25, it should be much safer.
The Hornady XTP's I have are .311", if they have changed them to .308" diameter, ignore my comments about .311" bullets.

I know about H110's properties...that's part of the reason I bought it http://www.ak-47.net/akcgi/smile.gif I'm sticking with Hodgdon, mainly due to the free manual they have to download on their site. I currently use h110, titegroup, and varget. THat pretty much rounds out powders for me.

It's the norinco ammo that is causing my slide to not fully close. I'm using .308 Hornady XTPs for my reloads.

I would have used .312 bullets made for .32 acp/mag/etc. But I've read that the necks need turning, especially on starline brass. PLus, I didnt find any bullets heavy enough in .32 to use them anyways. Plus, the chance that I could have a tight barrel...prolly not, but still.
