I've been thinking of getting blank cards and a mag stripe reader and get cc details and just print them on there and go for ATMs and unmanned stores/self checkout places. Has anyone tried it before? So far I've only done limited online carding but I figure this success rate may be bigger.

well I'll do you a solid and be a dick like everyone else lol
I think you'd be good if you found a source that had d+p on the regular.
I have yet to have any real success physical carding...just a few hits...was considering going in another direction...mind if I pm you about virtual carding?

How exactly did you figure that success rate maybe higher? What are you planning to do? Run blank white card 1 feet away from cashiers face? Do you have fake ID?
Dump+Pin? Yeah, my ass... 99.9% are scam or they charge $200/card with no Refund.. Or you have to buy 100 cards minimum, 85% of which are dead on arrival.. .. Besides, in US particularly there is $400/day ATM limit on 90% of the Debit cards... So you are basically paying 50% upfront on 5% success rate.. It's not even profitable.. Cause hey, lets face it, if there is "NO REFUND", they could simply ATM all good cards themselves and sell you 100% JUNK... Why not? No REFUND. So they can keep selling sh*t for $200/piece all day long... Good Luck...
"Quick dumb question" it's a Keyword which says it all.
P.S. You don't even understand what are you talking about:
"get cc details and just print them on there" LOL
Good luck printing, you really think real cards doesn't have any security features embedded? Sure just print the numbers and go shopping https://txgate.io/images/smilies/smile.gif))
