Gas checks for heavy Revolver loads

[Necessary_Nutrient]

I’ve been trying to both load hot and save a bit of money. Gas check- not to mention jacketed-bullets are very expensive but I do NOT want to cast my own.

Can gas checks be fitted to a quality coated bullet like the Acme or Missouri Bullet Company Hi-Trek coated products?

Calibers involved are 480 Ruger and 500 S&W.

There is such a thing as plain base checks. Sage reloading sells some.

ETA - They will fit only flat base bullets. I think that leaves out Missouri Bullets products.

Those loadings are very powerful and high pressure, and I expect that even checked they will require downloading for accuracy.
