Lifetime of Aluminum Gas Check Material

Please Don't Judge Me!!
For my first endless supply, I was counting on using 12 oz beverage cans. I found that most beverage cans were to thin (.0045 +- .001) I needed something thicker for my bullet base. So after a weekend of some Rigorous and Intense Research, Eureka!! (they must be the 16 oz Beverages) So far they have been working well @ .007 inch. Not only do I have a growing stack of Aluminum now. I have friends that insist on helping me. I sure do miss them.

I make my own .30 cal. aluminum gas checks.
I find that .014" thickness makes the best checks for me.

Define alot? What thickness is that?

If you're going to be pushing rifle cast bullets soda/beer can gaschecks are enough. Also doubling or tripling up on them in a pain and doesn't work out too good. Get the thicker aluminum material.

The pull lids are of a soft aluminum. I don't have my calipers with me, but I would say about twice as thick as a pop can or more.

The rolls of .014" thick aluminum roof flashing from Ace Hardware make really good gas checks. Just one session of making checks produces enough to last all year, and the roll will probably last a decade or more. I make my own beer, so I can't make gas checks from the bottles. :drinks:

I've used some of Ben's .314" Al GC's on Lyman #314299: They were a perfect fit on that CB's base. Furthermore, there was no difference in accuracy v. commercial checks (Hornady, Sage) that I could detect. In short, Ben's GC's fit that CB's base like a glove!

I'm glad you said that there was on difference in accuracy between your aluminum checks and commercial check. I tested that exstensively with more the one very accurate rifle and came to the same conclusion. Maven even to see if I could do it or if it would work I made a few check from the galvanized coated metal roof for a barn. The stuff is pretty thin, but thick enough to work. Punching checks from it wasn't any harder then when using the aluminum and they worked exactly same. I only tested and don't shoot them as steady diet, in fact haven't revisited them from years ago.

I assure all of you that I didn't drink or buy these and have had them a long time. These are the best for gas checks they are .014 think and you can get a lot out of each can if you cut into strips.

Please keep the politics out of this discussion! This isn't the PIT.

I have found that the .014" aluminum flashing checks work fine for me. I'm keeping MOA in my hunting rifle with them. I do think that sage's gator gas checks are sexier though. One roll of flashing (about $35) will last years.

.014” aluminum flashing works for me.

Old school paper cutter makes short work of cutting strips to use.

For the guys using beer/ soda cans… may I just double check, you are using those for PB GCs, yes?
Are they any different from the regular pull tab cans?

Instead of beer/soda cans, I've found that some of the energy drink cans are thicker. They are not as thick as coils stock, but it's definitely thicker than pop cans. The younger generation seems to supply me with all I need. I'll stick with coffee.

Currently I don't make any GC but looking around for suitable thickness I noticed the bulk olive oil containers (4lt or about a gallon) are a lot thicker than any beverage can I have found so far (I can't remember the exact thickness but at least double) might be worth checking out

I use a paper cutter too to make strips. Cuts the time down a lot and makes quick work of making checks.

they are steel, or am I making nothing into a problem?

The ones I have used are all aluminium, they are the ones from Italy so I guess genuine....

Been running .45/70 checks out of those this week. Definitely work real well for that if they'd only get their pilitics straight, there would be more around.

Get about 100 checks out of one./beagle
