OMG - Aluminum Foil patching !

I just ran across this while looking for Bullet Swaging photos with Google Images !

Some fellow is patching with Aluminum Foil !

He doesn't say very much about this, but I guess it works fine.

I don't suppose it would hurt the rifling.

I see that he is exceedingly consistent with the positioning of the patch on his bullet ...

People do all sorts of strange things. I'll bet there is someone patching with Emory paper too

[sharpsguy]

He might as well use emery paper. They use aluminum oxide to make industrial grade sanding belts. I buy and use a lot of them. No way I would run one of those down my barrel.

[rancher1913]

that looks a lot like aluminum duct tape, its a lot finer than foil and has a sticky side that holds real well. I think it would be easier to just get the right size boolit.

[Ballistics in Scotland]

All aluminium has a fine coating of oxide, which like anodising stops the extreme reactivity with the air which its atomic structure would suggest. But it is very fine and smooth indeed, so as to be entirely transparent. I don't believe it would hurt the barrel anywhere near as much as firing high-pressure incandescent gases through it, which we can do thousands of times before the damage is significant.

The Portuguese chose and immediately dropped patching with copper foil, when they found out that it caused inaccuracy due to unreliable detachment. Regular attachment or detachment would be about equally good, but centrifugal force prevents the former, and probably soldering due to frictional heat the latter. But aluminium is extremely hard to solder, even if you want to.

I think this material would work. It is quite good as a bearing material for a hard steel shaft. My only doubt concerns its thinness, which I think is likely to wear through and produce leading. The same material in soda-can thickness, even if annealed, would be likely to remain in the bore and act as an obstruction, unless we accepted the complication of turning the ends over to form a blind tube. But I think thicker foil, used just like a paper patch, would have real potential.

This pops up every now and then. Forgotten for a while then re invented again by someone else. Like masking tape, stick on shipping labels, Teflon tape, even seram wrap. Sort of comical and they say I been doing it for years LOL.

Several years ago on the old shooters, there was a discussion on making aluminum jackets out of pop cans for swaged bullets. The results where heavy galling and fouling worse then lead alloys.

Guaranteed to get a good grip!

[country gent]

I also dont see any ends and the gap or overlay of the 2 wraps of aluminum foil patches ends. Is he using square ends or angled what is the gap between when wrapped. Several questions come to mind with this. Will the aluminum foil "sweel when the bullet expands to seal the bore or tear / crack? WIll it be cut to release the bullet at the muzzle? And last after years of working in forming punching and forming parts How abrasive is it going to be on sharp corners of the rifling and lands grooves?

[JSnover]

I notice that thread lasted a whole nine days, right up to the claim of 2" @ 300yds.
Far be it for me to call him liar… but I do wonder why he got so quiet all of a sudden.

no CSI will be able to track the body to his gun

[DoctorBill]

Be careful what you say !

Hillary might hear of that and use it as one more reason to make guns illegal -
you can't trace Paper Patched Bullets to any rifle !

Do you imagine that she reads this Forum..........?

Ah ha, always wondered how come nobody used aluminum cans to manufacture base expanding projectiles for rifled muzzleloading cannons.

What I was thinking aluminum fouling. Wonder what kind of bore cleaner you would need to get that out of a barrel.

Pepsi?

[RogerDat]

You know I wonder if one could take aluminum beverage can metal and wrap it as a protective seal on the base of the bullet to prevent gas cutting?

Oh wait gas checks, silly me.

LOL, IIRC Winchester used aluminum for the jacket material on their silver tip ammo.

Only the tip was aluminum, the rest of the jacket, any portion that came in contact with the bore, was copper.

Actually, I pulled a .45 Silver Tip from a .45ACP case and found that the bullet is aluminum jacketed and had a canalure around the base filled with a green waxy lubricant.
