They don’t make a 100gr flat base in .243 anymore.
With that said, I’ve had better accuracy luck with flat base than boat tail in 30-06, but only marginally. Also .277 130 flat base shoot great and not available in bt in 130 gr, but in 140 gr.
When I search bullets on line I look at several calibers. Must have mixed-up boat tails and flat bases in my head. I dug through my modest bullet pile last night yep, boat tail 6mms.
