One of the big reasons that I need gas checks in the first place is that I am casting rifle bullets these days in order to make my target and leisure shooting less expensive. This is only a recent change for me, and in the past I have used rifles at the range more reluctantly, simply because of the relatively high cost of factory bullets. While cast bullets might be used for some hunting, that is where I stay with factory projectiles. Meanwhile, for lead bullet shooting, I would not tolerate gas checks that fall off the bullet after sizing, and with initial testing I don't find any problem at all with these checks. I haven't used these gas checks a lot, yet, but I appreciate Sage supplying what seems to be a fully good product with a bit less cost. I'm very pleased.

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.
