Never done it, never wanted to but if you load your 308 to duplicate 30-30 velocity they will work excellent. If you push them higher than 30-30 velocity (about 2300fps) you may run into explosive expansion and separation. If you load them +-10% of 2300 you should still be OK.

I am continually astounded at how quickly people make up their minds on little evidence or none at all.
