Can someone put up a table of the various sizes available and the "correct" ones for the available molds please. Seems shank size from the different mold makers past and present differs greatly. I would like to make this a sticky.

Can someone put up the physical dimensions and weights for the gas check itself for all calibers available?

Knowledge without understanding is a dangerous thing. For a little knowledge entices us to walk its path, a bit more provides the foundation on which we take our stand, and a sufficient amount can erect a wall of knowledge around us, trapping us in our own ignorance.

Knowledge is easy to get, but worthless if you never use it. However the info is free, so the only person you have to blame is yourself if you chose not to use the information.
Would 8MM gas checks work for the .303 British? Graf has gas checks in 8MM bot no .30cal which is what I have been using.

Its been months since I bought the book, "How to scam people online". It still has not arrived yet!

Yes, Bob, but under duress only. The dies might not hold the check square on the bottom of the shank before compression. You risk sizing one side of the check longer than the opposing side, i.e., lop-sided. ... felix

Thanks Felix, I'll wait for Graf to get some in. I have enough to do me for awhile.

This is a grid showing the gas check dimensions that I use in the bullet drawing software. When I get some more samples of the Gator checks and some time, I will add them to the database and incorporated a choice of brand name that the shank is to fit.
The software simply starts the shank at 0.002" under the "B" dimension and tapers the shank up to 0.002" over the "B" dimension. The correct height of the check is then drawn on the finished bullet image.
Ideally, 0.001" under "B" dimension generally produces the desired "snap fit" but, in my opinion, it is too easy to go too far and have an oversize shank. Better to be slightly undersize and have the ability to lightly lap the mold shank to fit than to have to expand each check to fit the shank before sizing.
Good info guys. Now to figure out what size to cut the cavity in the mold---Hmmmm, more hair just fell out.
Tom, the 512 Gator checks are of two flavors: rifle long, and rifle short. The lengths are 120 for the long, and 080 for the short. The 500 S&W pistol is of the short variety at 080. Looks like the Gator and Lyman for the 25 caliber are the same, except Larry tries to have a more rounded bottom on his checks. It appears his checks (in use) are considerably softer, and the more rounded bottom provides for some spring-back from the punch. His maximum shank might be a 1000s smaller as shown in the table, but I would not count on that in reality because of the rounded bottom. So, like you say, it is best to be on the safe side and make the shank a 1000s too small. We will get these checks on the GB list as quickly as possible. Any samples that I can get for you would not be kosher because Larry told me he is going to use a new lot of metal for these and all the smaller calibers that use this thickness of metal for our coming up GBs. ... felix

Need Hornady 416 and somebodys 475 checks to be added also along with the changes from Felix.

Could someone give me a shot of info on annealing gas checks? never been down that road but would like to try it on a 152gr Loverin bullet that has a large shank and I understand this might help cut down on culls? Thanks in advance fellas.

Sorry guys I didnt read down far enough, I get the idea.

Right you are Felix. I recently got a 460 mold that the maker made a booboo on and made the shank .010" big .425-.426 it was so I made a little tool to bell the check out. Worked fine. Ran em through the lee sizer. Then when I lubed em in my RCBS lubesizer (I do it in a two step. I'm a believer that sizing and flight direction should be the same) some of them were great, some left big gobs of grease underneath. I get fliers. When you carefully look at em under glass one side of check always has more sizing contact. I'm sure the .010 oversize is ruining accuracy
Yeah, if the mold is a prized one, you might consider someone like Buckshot make you a luber machine die to shrink those boolit shanks to fit the "standard" checks. The die would be nothing but a solid roll stock (aluminum) with the top center shaped dimensionally correct as to swage according to the check length and diameter. No die machining would be required to hold the die in place because the residual lube from the last operation would be sticky enough to hold the die in place. ... felix

Had a whole box of 8mm Sierra crimp-on gaschecks that won't fit the Lee 175 gr. so here's what I did. I put a .44 case trimmer pilot into my little drill press & expanded them out to fit the shank. Will break down & buy a box of checks soon as I use these up. Never saw these before or since. I either got these off E-bay or had them under the bench from the old days.
Has anyone ever tried to put a well annealed .375 cal. gas check on a .35 caliber boolit? The reason I'm curious is because I thought of trying this with .360" SAECO 352's shot hard from a wide grooved 336. The .35 Hornady checks have a tendency to separate form the boolits. I currently don't shoot .375 cal. rifles and if it won't work for sure, I don't need to order more shootin' supplies that will end up collecting dust (besides, I already spent over 1000 bucks today on gun stuff). I was thinking the annealed .375 check could be formed by a top punch in the Lyman 450 that fills the .360" die (punch number 141 comes to mind as a possibility) and then applied to the SAECO 352's. Make sense?

I ordered a new SAECO 352 about 2 yrs. ago , my .35 cal. Hornady gas checks didn't fit well at all. Very loose. You could pull them off with your finger nails.
I figured that at the prices SAECO's charging for their new molds that they could provide a better product than what I had received.
I called them on the phone. The fellow wanted to give me the " run around " at first. He told me to change my alloy, etc. He got a little argumentative. I told the fellow that I didn't plan on spending any time arguing with him.
I told him that I planned to use reg. WW's and that I also planned to send him the mold and 10 of my gas checks and that I wanted a tight fit....PERIOD ! ! I told him I didn't plan on using HIS alloy , that I planned on using my alloy !
About 20 days later I received a new mold. This one is PERFECT. No loose fitting g/c's now... I believe the 1st mold was " way out of spec." on the gas check shank of the bullet.

does not hornady now make lyman checks???
