I am wondering if my chamber might be a bit on the large size in comparison to my die?

I brought my 6 up to the range today, but didn't shoot it because of the wind...My 300wb at 25yards didn't have much of an issue...Every frig'n time i go to the range now with that 6x223 it's windy...I'm done shooting in the wind trying to get groups...
