How to Install Gas Checks Cheaply

If you reload long enough the draw to cast your own bullets becomes almost impossible to resist, its one thing to assemble to bullets, but to actually make them is something entirely different (and next comes swaging, but I am still trying to convince the wife to let me spend that money). Casting is relatively simple, but when you start using cast lead in high velocity rounds like what you encounter in rifles you have to ensure that the bullet does not get eroded by the hot gasses, or stripped bare by the rifling leaving heavy lead accumulations in your barrel.

A light coating of case lube (e.g. Dillon's) will make the bullets' trip through the sizing die much easier. From my experience, the Lee sizer die is the quickest and best way to seat the gas checks. They always seat squarely and evenly. I apply lube in a separate step. Yeah, a separate step, but I"m retired and have plenty of time! For rifle velocities, a BHN # of at least 18 is preferred, or better yet, linotype with a BHN # of 22. Great video!

Wheel weight does NOT have sufficient alloy in it to "harden" very much even when quenched.
You must add a bit of: TIN (5-10%)
Antimony: (5-10%).
This, unfortunately will increase casting temperature as alloy increases. Start off near the lower % first.
You can then choose to quench after casting with greater effect.

I just started casting for my Enfield as well.My Lee mold is a 160TL and the bullets come out about .312.I don't have a sizer for .311 so I just put the checks on the base and whack them with a small hammer.They don't bulge the case necks and chamber just fine.

[@TNGun]

I haven't done it, but I believe so, if its the loader that I think it is - its a tube you smack with a hammer right?

[@Dietzeeeee]

I am confused as well. So I could use the same 357 mag sizing die that i run my brass through remove the depriming stem and use that??? I am thinking about getting into doing cast bullets for my ruger 77/357 rifle in 357 mag. I have handloaded before jacketed and hard cast bullets but I have never done gas checks more info would be great.

[@danietkissenle]

ya thats the one. i just started reloading 30-06,and i don't have one of those presses so i cant use the use the crimp die and i want to cast my own bullets

[@1TruPatriot]

Excellent Video Bro!! It's all a learning process. And you my friend, have learned a lot. Thanks for sharing the video Bro!! I learned a lot!!

[@spinesales]

Gas checks are great. You can push 'em so much faster! How are you lubing you bullets?

[@TNGun]

I was using a sizing die and a press

[@williebulletman5217]

Hello sir I always loved the 303 round great video I just sighed up for your General hope you wouldn’t mind signing for mine willie bulletman thank you sir

[@TNGun]

@phatmrziggy Yes, but not when I took this video. I pan lube those rifle bullets, but that's going to be another video

[@dkeith45]

So the gas check prevents leading by, removing it as it passes by?

[@johnanderson186]

The gas checks prevent leading by protecting the base of the bullet from direct flame and pressures. The gas check obturates to seal the bore and also prevents gas cutting.
But they still only protect to a certain amount. You still cannot push the bullet as fast as jacketed bullets, but can push your cast bullets at much higher velocities and pressures compared to standard lubed bullets.
Powder coating adds even more protection from leading when coupled with a gas check. It’s not the velocity that causes leading it’s the pressures mainly that create the leading. Learned that in the Lee reloading manual. Great and very informative manual.

[@sammysame]

Good informational video - would've been better if you showed us a finished bullet with a gas check installed on it.

[@danietkissenle]

is there a way to do this with a lee classic loader

[@KilroyTheGrand]

I had the same idea using the sizing die

[@matthew262]

Good info, thanks.

[@lestergillis8171]

The bullets being sized & gas checked in LEE dies MUST HAVE a bit of LUBE on them BEFORE sizing.

[@lovshooting]

Do you lube them first?

[@TNGun]

@MPSecare Even less can say they make ACCURATE bullets, I am still working to join THAT group... LOL

[@521Bobcat]

I Still Don't understand what equitment needs to be used to crimp a gas check!

[@maxgiovanna1966]

Hi
I'm new to reloading, sorry for the dumb question. Is that die specifically for installing gas checks?

[@mojofish1]

+maxgiovanna1966 For supersonic rifle ammo its to help push the bullet since the pressure is so great. In a non magnum pistol pressure is greatly reduced and not necessary.

[@TNGun]

Yes

[@samiam619]

How is this “Cheaply”? It’s just the normal way to do it… Also, it’s 2023 and Hornady copper gas gas checks are $58 per 1k!

[@bsibs]

I'm new to this, so I need some advise. Can you, or do you size the bullet while you are installing the gas check? Or is sizing and installing the gas check two seperate processes?

[@trbig67]

1:25 of the video, Sammy.

[@charlesirby9222]

Howdy Shepard School …Sizing with the Lee sizer just got fast…please watch this short clip we put on You Tube in order for Lee to look at it and possibly modify their sizing approach.

If you agree please contact my pard, Thom Finks as it is on his channel…I don't have one as yet. Thank You…charlie

@spinesales pouring them in a bowl with Lee Bullet lube and shaking them.
