Here's a quick and dirty comparison between the two with the .308 a little more than twice the distance of the 22LR:
22LR 40gr high velocity with a 50 yard zero in a 10mph crosswind:
200yds drop of 40", drift 17"
300yds drop of 114", drift 33"
.308 180gr Nosler with a 100 yard zero in a 10mph crosswind:
425yds drop of 41", drift 15"
625yds drop of 116", drift 36"

And out somewhat further:
22LR at 450: drop 305", drift 67"
.308 at 925: drop 315", drift 85"
So yes, the two have quite similar ballistics at their respective ranges. Makes the .22 a very effective learning tool with 1/2 the range required to shoot at, much (much) less expensive ammo and generally a lower initial investment also. The only downside is the 22 probably won't hold MOA out to 450 yards, but everything else you learn will transfer over to the 308 very nicely.

Yes, there is a member here (can't remember his name, clayne clain?) who does .22 out to 500m and has the video to prove it.
Sure you have to aim meters above the target but its possible.

Similar sights are a bonus to the shooter using them.
I have a BSA Martini Model 13 in 22 rimfire with it's original peep sights.
It's a good understudy for the Wichita 1375 in 308 with Centra peep sights.

I'm biased...I love my .22's. I do have "heavier" shooters too...
Not just .308 shooters benefit from using their .22's. All riflemen do. Your "discipline" should be the same whether it's a 'lowly" .22, the .308, or the .50BMG. Physics laws apply the same to all of 'em. The good news? .22's are cheap, quiet, and very affordable to shoot. I dunno anyone who managed to acquire a flinch from their .22...
In the link I provided are a few fine .22 vs. .308 comparisons... [very] roughly half. You shooting a .22 at 200 yds is great practice for a .308 at 400-500 yds.
The only caveat I can think of? Getting 525 rds. for 25$'s and a 100 dollar .22 might tempt a shooter to "spray n' play"...that could be "counter productive" to someone training.
I think the member here is ClayneB...his youtube videos garnered enough attention that he joined up. Does wondrous things with his .22 to crazy distances...just makes me jealous. I push it at 200yds to get close to my targets, but there is a good reason the box 'o' shells says dangerous to a mile!

The relativity of .22 and .308 doesn't matter so much. But practise with a .22 is good for all your shooting. If your .22 has similar weight and feel, optics, and trigger as your bigger rifle then it is VERY good practise for using your .308. You can learn and practise trigger control and breathing just as well on a rimfire as a centrefire, and you shoot 500 rds in a day for less than $30. Try that with a .308. 
Most people would improve their shooting by shooting more .22. A 50-100 yd range and a brick of shells in an afternoon can make a better shooter of most of us.
