These thicker gas check will help with that little more you need at times with a problem cast bullet , don't be afraid to try these .017 checks they are the same top quality Sage's copper checks but with a little more meat to them .

I use Sage checks in 30-06, 30-40, 7.5X55, 7.62x54, as well as a wide variety of 8mm's. The checks work great and cant beat the price. Highly recommend this product.
