My opener was yesterday in a 30 acre sunflower/corn field. I drew a marginal stand, but adjusted and found a spot just off the edge where the birds would leave the field after running the gauntlet. It was sporty shooting at incomers which to me are the easiest shooting. It was the first time in the field with this 90+ year old R-10 which went from a Damn gun to a Darne after a few shots. The state limit is 15, but the field limit is 12 with the group. I managed a limit of birds in just under a box or was it a flat? Well, somewhere between a box and a flat of Polywad 16's, 7/8 oz. of #7.5.
