I ordered aluminum gas check material from CoilAndFoil today.

1/2" x .0145" x 50‘ $5 per coil, maximum of 3 coils per small flat rate box, shipping is $6.00

3 coils X $5 = $15

The second photo are the groups using Hornady gas checks.
I cannot explain the shot inches low in the first group.

Did you trim these cases to the correct length before seating the bullet? I do not read the word trim in your posts.

I thought you would use the powder. It is probably a fast burn rate pistol powder, so do not use it in a rifle cartridge under a j-word bullet. If you use it in a pistol cartridge with cast...

That is what I have read, but I have not tried it.

I think you mean $0.002 per gas check and $0.0058 per gas check respectively.

I do mean that.

0.2 cents each = $0.002
0.58 cents each = $0.0058

When I said more expensive, I was only figuring the cost of the aluminium for the gas checks.

Thank you for the explanation. Bonding the layers of soda pop cans together is too much effort for me. I have calculated the aluminum roof flashing to cost 0.2 cent per gas check. That...

I do want to try Yonky's coils. They seem to be slightly more expensive, but not having to cut the roof flashing might make it worth it.

I am using Pat Marlin's .30 caliber Checkmaker.

gas checks made from 1, 2, 3, and 4 thicknesses of soda pop cans can be pulled off the bullet after sizing.

See photo....

I too have been flaring gas checks with a flat nose punch modified with a taper to get the correct amount of flair. See photo.
Notice the 7mm and .30 caliber punches are the same diameter, but have...

Treekiller,

Good idea. I cut off a 9" piece and it worked fine.
I will want to purchase wider rolls of flashing next time.

Chris,

Before you spend any money, I suggest that you slug the bore.
Then you may learn where the problem is.
