A 30-30 is a brush gun. In it's time it was great, but that time has long past and there are too many cartridges that are superior to it now.
I know what you mean. Ever since they came out with the new tougher Whitetail v2.0, the .30-30 just won't knock 'em down. Back in the day, a whitetail deer was only a thin-skinned 90-150 lb. animal that could easily be killed at up to 200 yds. with almost any mild center-fire cartridge. Nowadays, wow. Those up-armored, moster brutes will scoff at anything that doesn't say "WSSSSM" on the label!
Honestly the cartridge almost annoys me and I'm tired of hearing about it period.
I know what you mean. I think if anyone else ever says ".30-30, .35 Rem., .257 Roberts, .243 Win., .30-'06, .270, .32 Win, 7x57mm, or .303" to me I'll probably just puke on his shoes. You can't call yourself much of a hunter if your cartridge doesn't say "RemChesterSuperSuperSuperShortDoubleUltraMagnum" on it.
My father has seen a guy shoot at a deer and miss twice with the 30-30 at 100yds, after that he put his crosshairs on him at 200 yds and dropped him with the 270. Made the guy sick to his stomach and probably hasn't used it since.
OoooooH! I HATE it when somebody uses a .30-30 and it does that to them! I'm surprised he didn't wrap that rifle around a tree! I know he probably didn't realize when he picked that gun up that the .30-30 cartridge would make him miss at 100 yds, but I'll bet he cussed it good when it showed it's true colors that day. What a LOUSY cartridge!
As for the 7.62, I'm sure it would do a good job, but I'm just not a fan of using military rounds for hunting.
Again, I feel you! .45-70, .30-40 Krag, .30-'06, .303 Brit., .308 Win (7.62 Nato), 7x57 Mauser, 8mm Mauser, and so on, might have been adequate to kill a 150-200 lb. man in the trenches of the battlefield, using FMJ military ammo, but they're just unethically poor for killing a 90-150 lb. deer in the kind of field conditions we face these days, with soft-point/expanding bullets.
People need to get with the program!
