Huummm- the late Bert Popowski, Dean of crow shooters in a by-gone era- used 12 gauge No. 9 skeet loads in his Ithaca M37 with a modified choked barrel-- Of course, we are not shooting crows for the table, neither barn pigeons or other trash birds, and as he so wisely pointed out, 90% of the target area on a crow is the wings, they have slight body mass-- I once found a close out sale on a flat (10 boxes) of 12 ga. AA No. 9 skeet loads (about 10 years ago) and used them with great success on crows and barn pigeons. RWTF
