    My guess is that since he is from Finland and they appear to be aluminum he is making his own. I'm not sure how St Bach might have gotten checks on his. I have some Gators and Hornadys here, can't find the old Lymans that I have. I took a few of both and put them on a aluminum plate and heated them until they got soft. Then I took the round end of a small ball peen hammer and pressed it in to open them up. No way are they going to fit on mine. Whats got me bamboozled is out of the group buy only about three if us are encountering problems.

    I will admit, my checks are made on a FreeChexIII out of aluminum and they were pretty tough to get on. I checked all the ones Iíve cast with this mold prior to noticing the issues everyone was having otherwise I would have done a little more testing between my hornaday check and the different thicknesses I have. This is not an offer of sale by any means but if someone wanted to do some testing I could sell/trade them some of the checks I made if they want? I donít shoot 44 a lot but got in the groove and made some extra checks a couple weekends ago so I could spare some of what I have. Send me a PM if interested.

    For those of us making our own, another thought I had was sourcing some slightly thinner material to cut them out of to make these easier. I use .014Ē thick sheeting currently based on Pat Marlin recommendations so I was wondering if there is a source for 0.012Ē or even 0.010Ē available to try? I know some say you can make out of soda cans but those come out too thin in my opinion and donít stay on great (though didnít test that against these bullets either).

    Note: I am happy with my mold and not trying to complain about the shank as I didnít have too much of an issue. Just trying to assist those that are having issues.

    I finally had a chance to get some more cast up and my gas check shank came in at .418Ē with 94/3/3 alloy. I have the .432 4cav HP version.

    I ran a little test with the three types of checks I had on hand: Hornaday (roughly 2014 purchase), vintage Ideal (1950s era), and my own Freechex III checks made with .014Ē aluminum.

    Freechex were by far the easiest to apply though they were still a bit tough. Vintage ideals werenít bad but did shave a little lead when being applied. The Hornaday were by far the hardest to apply. They actually cut into the lead that had lead coating the outside rim.

    All were able to be applied but I did have to use some case lube in the die to get them to run through as this bullet is slightly oversized with my alloy and my Star .429 sized struggled a little. Actually had two of the test bullets with Hornaday checks get stuck to where I had to drill them out, but no issues once I used the case lube. If using normal lube in sized or tumble lube on bullets I suspect you wouldnít have an issue.




    Here is photo of Hornaday check with lead cutting on outside of the check (right side in photo). Please not lead cutting makes check look like itís uneven but it is on square.

    Moral of the story, use checks other than Hornaday and youíll likely be ok. Do I wish shank was slightly smaller to fit checks easier, yes, but do I feel itís outside of acceptable tolerances to where I need a replacement, no. I have other 44 molds that have tight shanks too so this isnít outside of normal I donít think.

    Thanks for the post! Took me half a month to notice. The Closed Buys Icon has been white (no posts) so long I gave up looking.
