Magma molds odd gas check sizes

[chloe123]

(Crud, I realized this topic should be in 'molds'--apologies)

I hesitated on ordering a few Magma molds when I read that some have unusual shank size for the checks. They don't produce many gas check designs, maybe 10 or so. I was interested in the 454 Casull(.452) mold and probably 500L.

Regarding the 452 boolit, apparently convention is .426 for the shank--but per a post from another member a year some ago--he measured .430 on the Magma. This limits using the typical copper gas check for a 45lc from the popular makers.

They do sell 45-70 (459 I believe) molds but (1) I don't know if the dimensions for the GC would be different (2) I'm not sure how wise it would be to size a bullet down to 452 without an additional in between die, like a 454

I want to support Magma but if it turns out the shank is unconventional size I may have to look elsewhere.

Any of the fine Boolit members have experience with GC designed Magma molds?

Chloe,

We have some experience with 454 Casull molds and gas checks. We might be able to help. Please feel free to send me a private message or use the calculator on our website to determine what thickness gas checks you need.

Thank you for the response and will keep you in mind for the future. I'm a fan of Magma and wanted to support;however, I had to look elsewhere for GC molds due to limited--and in the case of the 454--unconventional design. Fwiw, I looked to Tom at Accurate Molds.
