Perry- it is always suggested to not have the gas check below the case shoulder. This is a suggestion only, not a hard and fast rule. Some rifles shoot just fine, with the gas check beneath the shoulder.

Merely seat the bullets more deeply where-ever they have to be to chamber, and try them out. There is no reason you cannot at least try them in your rifle, unless they are TOO large in diameter to allow the neck of the case to enter the chamber.
