Weird rimfire project...

[Mystic Precision]

Before you worry about the ammo, can you get a fast twist rimfire barrel?

That ammo will not stabilize in standards twist rimfire barrels thus the sideways holes noted above.

The Heavy Aquila bullets usually came from suppliers that also offered fast twist 10/22 barrels as this was the most likely platform used.

Some BR rimfire shooters use top grade ammo from Eley and Lapua then tune their barrel for that particular harmonics. Reloading in reverse.

plus with RF ammo primer consistency is key... if you want a tack driver then you would be useing hi-end ammo for takedown's to get consistent pressure, if you just want to plink then cheap bulk stuff would keep the cost's down....

too bad you cant wildcat a .22lr or mag case with a .223 bullet because your bullet selection go's WAY up.....

I have done some research.
I plan to use my TOZ-8 single shot rifle for this project.
As for variances in weight, I certainly can weigh each bullet/case, and discard any rejected component.

An update here:
If anyone on CGN in the near or far future wishes to acquire an unusual small bore lead mould, I strongly suggest this company;

Old West Bullet Moulds
In Fruita, Colorado
speak to/email a Bernie Rowles.

This is our only option, that I am currently aware of in North America, for custom .22 lead bullet moulds of healed designs.
Mountain Moulds and Lee Precision, do not do custom work, for any .22 calibre.
I believe the smallest calibre they work with, is .264.

here is a mold for you.

HHHhhhhmmm, my money is already sent to the first company.

Thanks Buckbrush though, I will definitely save this to file....

Cheers

A few years ago I saw these on sale and I just had to buy them. I'm not quite sure why though.

 

[Big JD-From the hills]

what about a 25acp necked down to .22cal?

 

[Threemorewishes]

I have one full box left...make me an offer I cant refuse and their yours.

John C, If you know of a current source for Aquilla Super Sniper Subsonic 60 grain 22 LR in Canada I wish to know?

 

[Brutus]

Kind of a neat idea JD, but I wanted to be able to pull the bullets on a rimfire
and use that case.

EDIT: What kind of ticks me off, is that is a week ago I emailed Lee Precision, and at no time did they mention this Reproduction Mould at all....and Lee Products refered me to Lee Precision.

Oh well.....

All I wanted to look into was making my own equilivant to 60 grain Aquilla SSS.

Why? SSS is marginally accurate if it will even fly straight out of your rifle. I have tried it in several rifles and a pistol and it groups larger than I'd like although it at least flew reasonably straight without keyholing. That is not to say it will be stable out of your rifle as noted by earlier posters.

SSS is NOT any quieter than other subsonic rimfire ammo, even with a suppressor. It is actually worse in semi-auto's because the short case clears the chamber before the pressure has dropped resulting in a louder pop.

SSS is a very specialized ammo that really has no use in normal shooting applications. There are all sorts of subsonic rimfire ammo's out there that are a better choice. I'd suggest trying them before you spend a bunch of money on this project.

IF you just have to try the SSS I'll send you 10 rounds or so to play with ... gratis. I have several bricks of the stuff and never use it.

I also shot SSS into wet phonebooks and found that somewhat erratic behaviour. Sometimes they simply traveled point forward. Other times they yawed 180 degrees to end up base forward. They never expanded, broke apart or otherwise deformed.

IF you really want to do something important. Figure out a heavier .22 rimfire bullet that will stabilize in standard twist rifles and have the capability of expanding in tissue. Make sure to use a powder that will minimize noise signature for use in suppressors. THAT would be worth something.

My purpose is for close range harvesting of fox in an area of rural farmland in the valley of Nova Scotia, and the eldest owner of the neariest piece of land is adamant that we use 22 rimfire only, so we dont scare his highly nervous horses.
I have tested SSS Aquila for hunting level accuracy in more than a few rifles already,and I have a TOZ-8, 22 LR russian single shot, and a TOZ-17 repeater,that both are actually okay for groups, so for whatever reason, barrel twist/bore leade.

The report is quiet enough as it is.
The foxes are attracted by the chicken coop, and we have an excellent view of the yard from an old hay loft of a barn.

In Edmonton I spoke with a varmint shooter who used these rounds on dogs preying on sheep in central Alberta.In his words he stated that within 55-65 yards maximum, and knowing your hold, many dogs struck were one shot kills, (mostly head shots) irregardless of thier size.
On small to medium size dogs, complete penetration of skull, although I believe he meant at relatively close range.

 

[Big JD-From the hills]

Well if its just foxes your after, just regular or sub sonic hollow point's would be my choice. Solid 40 grain sub sonics would just zip right through, the hollow points atleast have a chance at expanding or upseting.

 

[Brutus]

To increase knockdown power I plan on using the "Paco Accurizer."
Google it sometime and see what shooters are capable of with it....

 

[Suputin]

I measured 7-9 inches of penetration in wet phonebooks with SSS. It is likely to penetrate even further in flesh. You would definately need some type of hollow point to increase lethality in smaller game.

 

[Brutus]

Thanks Suputin!!

I was at the range one day and walked over to the small bore rifle range. One of the competitive target shooters was practicing. Walking to that range I heard the report from the gun and then the impact from the bullet hitting the paper 50 meters down range. The sound level was about the same.

I walked over and asked him about it. He smiled, then showed me his gun with a sight extension on it. The barrel of his gun was shorter than you would expect for a precision rifle. This is to reduce muzzle rise. The tube extension allowed the sight to be further out providing a longer sight radius.

The blast from the muzzle was able to dissipate somewhat in the volume of the sight extension and the sound level was reduced. Not quite a silencer but it was effective. As I said I heard it from the side. I'm not sure if the effect would be as great in front of the gun.

I found a few listings for sight extensions on the net but I thought the one that I saw was a larger diameter.

 

[Brutus]

Rudy, this looks like a bloop tube to me, they are primarily designed to increase your site radius on iron sighted target rifles.
And yes I have heard it alluded to, that the a side effect was certainly reduced report.

 

[22lr]

SSS is NOT any quieter than other subsonic rimfire ammo, even with a suppressor. It is actually worse in semi-auto's because the short case clears the chamber before the pressure has dropped resulting in a louder pop.

I understand project is for bolt action rifle (TOZ was it?), anyways, for semi that pop can be fixed by adding weight to your bolt. The easiest way to increase weight of bolt I think is by installing custom-made charge handle that is bigger and heavier that stock one. Heavier bolt will accelerate slower allowing bullet to leave the barrel.

I toyed with 22rf reloading idea as well but I thought more of re-sizing 224 bullets and compressing tail section to smaller size. What put me off is twist rate, I couldn't find any blanks in faster twist.

Anyways, good luck with your project and please keep us posted.

 

[Brutus]

I certainly will post progress here, my money is already gone to Old West Bullet Moulds, so, just a few other technical details and some actual testing to sort out really.

Along those lines 22lr, I have given consideration to having one of these russian .22 barrels removed from thier action and have a gunsmith rechamber and rebarrel to a Ruger 10/22.

Cost and perhaps negative results, are what is giving me concern for this step though.
As one rifle would surely be ruined.
