light weight .30 cal
Two things come to mind if you are looking for lightweight .30 cal to shoot; the first is to resize .32 ACP bullets using a Lee Sizing die #90037. 60 grain hollowpoints are available - Hornady XTP hollowpoints, for example. A couple of passes through to compensate for springback should do the trick, according to Lee. That's a pretty light bullet for plinking or whatever.
In addition, there are chamber sleeves that allow you to fire .32 ACP directly; Sportsmans Guide,
http://www.sportsmansguide.com/product/index/32-acp-rifle-chamber-insert?a=471502
has them for about $15.00. Can't get much lower recoil than that, and you can practice with a known-working round and switch to handloads when in the field. They're available for .30-06, .308, and .303; there are probably others; Google chamber sleeves or chamber inserts.
The second is to use sabots for .308 diameter bores, and use .224 bullets in the sabot. You can get, for example, 40 grain or 45 grain spitzer boattails, with decent BC's for downrange performance - the .32's are practically round ball - and when you add the ~15 grains of the sabot, you are loading for a 55-60 grain payload. You could even use cast bullets, because the nylon sabot won't lead the bore - the bullet never contacts the rifling. Or go lead free, down to 35 grain Hornadys

You can get the sabots for about 8 cents each:

FWIW.
