Those 7 grains less than a 243 make the 6XC that much more enjoyable to shoot. A number of people extoll the fact that the 6XC is very easy to load for, and thus far my experience is proving this out.

I love the 6mms, and I've had at least one 243, 243ai, 6mmBR, 6x47Lapua, 6x45, but I think the 6XC is becoming my favorite.
