6 Creed vs Fast Twist 243ai

[HighUintas]

One drawback I hear people say about straight 243 is having to trim all the time. Do you really need to trim that much?

Depends how short you trim. I trim every other load . For an off the shelf die, get a forster. It sizes less than the other ones like rcbs, Hornady, Lee. Then you can also have them hone the neck to whatever size you want so it reduces case growth even more. I like my forster FL die a lot
