Gas checked bullets are by far my main projectile, and Sage provides all my gas checks these days.

My recent 2000 gas checks are the best I have seen from the company; fit on the bullet shank easily; nice flat bottom and grip the shank after sizing very firm and look very concentric to the bottom driving band.

I use these on my cast Bullets and Copper is the only way to go ! I would never put aluminum down my barrel...These Checks work best for me.

Sage's gas checks are my go-to for all .30 caliber cast bullet shooting.
I load .30 Carbine, .30-30, .308, .30-06, .300 Win Mag, .303 Brit, 7.62X54R and .32-20. I cast a wide range of .30 and .31 bullets and most have a gas check shank. Now if IMR would just resurrect SR 4759!

I use the with all my 30 Cal. GC rifle bullets. They fit well and stay crimped on.

Got these to gas check bullets for 30-30,30-06,765x54 Argentine and .303 British. They work beautifully, very impressive. I have sizers from .310 thru .314 and these stick to the shanks on every single size. Highly recommended.

Hornady gas checks 30 Caliber: Cost $47.99/1000
Gator gas checks 30 Caliber: Cost $29.00/1000
They both work well.
Hornady provides a nice box for $18.99 more.
You choose.
