I'd like to introduce my 10 year old daughter to Trap Shooting. She is small in stature. Thankfully I have a Stoeger Condor with interchangeable barrels in 12 and 20 gauge. In terms of minimizing recoil which way would be easier? If I do go the route of the 12 Gauge, is there a particular low recoil shell on the market that will not break the bank?
