I'm talking to a person about his TOZ and he mentioned that HV ammo did not eject well, SV no issues. But that made me wonder if using HV ammo could have a negative affects on the firing pin, bolt face and who knows what else.


Anyone have 1st hand knowledge?


Thanks,

Toz takes a firm snap to positively eject brass; even Tenex. Not a big deal. He’s not going to hurt it.

Thank you. This is a great forum. People are willing to help. It becomes a matter of reading, thinking and rereading the comments and advice. Then sometimes I realize I'm in search of a problem when I don't have one. That there is a problem no doubt.

HV won't bother the action on the TOZ-35(M), but the chamber is tight and fouling can build up quickly and cause the extraction to be poor.  I would often start having extraction troubles near the end of a match, if I didn't start with a really clean gun.  Additionally, different bullet shapes cause different fouling patterns, so swapping ammo without a good cleaning will often show poor extraction, as well.

Now I just have to get one. I blew one opportunity with one of FORUM people. He decided to keep his while I was dithering around not sure and all sorts of BS from me.

Oh well if everythig closes I'm going to get a few rubberbands and some paper clips and shoot into my 22 bullet trap that I used when I had an air gun. and dry fire too. No not the rubberbands.

Forgive me asking, but why would one shoot HV out of TOZ-35M (or any free pistol for that matter)? It is difficult enough to hit that target with SV ammo Smile
Or were you asking about IZH-35M (semi-auto pistol)?

Some one who was selling one brought it up that they were having an issue. I ran it by all of you here to see what could be gleaned and gave him back the data. He wasn't a real target shooter and had a question. I think he may have changed his mind about selling it and might become a shooter.

I'm old, he's young. Best to him.

Shorter barrel time.

I read something about more turbulence exiting the barrel on HV.

since you asked, I was thinking maybe more recoil? I don't use it so no matter.  But shorter barrel time means less time to screw up on the hold/follow through, no? However, then then given the added recoil, it might be a wash.

Again, just a thought. I have not done any studies.

The real issue for Free Pistol ammo is to get the ammo that produces the smallest group at 50 meters.  That might be HV or it might be SV, or anywhere in between.  It's all single shot and the recoil is pretty much straight back if you're using an actual Free Pistol.  Lock time is quick with a spring loaded firing pin.  Barrel time really shouldn't be an issue, either.  So what if recoil is heavier for HV ammo?  You don't recover for another shot.  You have to extract the fired case* and manually load another cartridge before you can set up for the following shot.

* Obviously, if you are using an auto-loading gun, the fired case will most likely be expelled by the action, but you are still required to manually load the next round.

I would leave the discussion of recoil and follow through to you and others. These are interesting points. If and when, or when and if I get one of these I'll make a collection of specific notes and combine them with my Nygord notes.

In the mean time I'm dry firing and shooting paper clips with a rubber band into my 22 trap.
