Lot of good suggestions.

You just gotta get into reloading if not already there. Too much difference with what can be accomplished. And, it's enjoyable.

The .243 is a good one for the non-reloader, as is the .308.

I'm partial to the .257R over the .243. I don't see .243 loads pushing 100 gr. bullets at 3,250+ FPS...

For the .257R to really shine, I'm thinking a 3" box mag. That's an expensive proposition, converting a SA, or one can go LA. I know there's wasted space in the longer box, but I'd rather have the room than not.

IMO,
