Is it possible to receive VA Benefits if you are 10 days short of 24 months active duty and went IRR due to dual military and then act res?

You may, and you may not, it would depend on a host of things. Did you do a combat tour, awarded a purple heart? What year did you go in? A service connected disability? There is some gray area here, and there is not enough information to give you a clear definitive answer.

I would think even being a reservist if you completed the required time on active duty that law requires you would be eligible ! The best one to answer that question is the VA regional office near you or your county veteran affairs officer who is supposed to help you with filing claims for benefits! Remember that if you have a service connected disability you may be eligible for vocational rehab henefots which are better that your regular GI bill.
