I never said it was a poor choice for everyone.
"AFAIC" means As Far As I'm Concerned.
From my perspective, "I" prefer a 99 or BLR in 308, with or w/o a scope, to/over the 30-30.
No one has to agree with me. Some like red, some like blue. et.al.

I'd like to throw in my support for this. This is exactly how I ended up, and after trying to get the results I wanted with a Marlin 336 in 30-30, I finally ended up with a Savage 99 in 308 Win and it has been my favorite deer rifle for over a decade.
My biases with the 30 WCF come more from expectations than anything else. Up until I got the Marlin, I had not killed a deer with anything other than a 30-06 or 12 GA slug. It did not help my opinion when the first deer I shot with it appeared wholly unfazed.
Ode to a 30-30 Pt 3 --- Like a Dog Returneth It also did not help my opinion of the 30-30 that a lot of my neighbors carried them and used to unload their magazines at the deer in futility. However, this is something you would expect from folks that routinely tried 300 yard offhand shots. Their beer cans still litter my woods.
In regards to the .243 WIN, I have very little experience. My sons are all walking landforms like myself, so after a year or so on the 30-30 they switched off to 30-06. I never had to come up with a traditional yute rifle. However, I have a grand daughter now--celebrating her 4th birthday this weekend, and my interest in .243 WIN has been renewed. My only observation comes from the years I've spent here and elsewhere reading other folks' opinions.
It would see to me that 243 WIN shooters as a class seem to be the most concerned of any with premium bullets and bullet failures. This bullet explodes. This one pencils. This one failed on a shoulder. That one went in a ear and bounced around, etc.
I even remember someone wondering if it would not be better to take two different loadings out. Their favorite long range bullet seemed to blow up at close range, so they were looking for a second round they could toss in if a target showed up inside 50 yards. I offered the advice that I would stick to one loading, but let the closer animal wander a bit farther before shooting.
I don't mean to impune either of these august chamberings. However, I must say that, in the case of .243 WIN, would one of my favorite .308 165 grain Hornady Interlock SP's fail, I would expect the largest chunk to weigh more than a pristine .243 WIN.
As Jerry said, AFAIC.
