A 243 is better than any load you can shoot out of a 223.
I'm going to go ahead and call bullshiit on this comment. And I'll go further and claim you're talking out of your ass.
As to the OP's question, it sounds like you've got a damn near perfect deer load there.
Call anything you want, but the 243 is a better choice for deer than a 223......and it's not even arguable.
*Yawn*
STFU boomer. I was right about the talking out of your ass.
Alright Gentlemen, we're all friends here.. Use what cartridge and bullet you want, in what caliber ya want...
