Well, I never miss! The dog screws it up, the gun is awkward, the sun is in my eyes , the damn bird makes an unwarranted move, daaaang! But here's my contribution;
Just this last season in fact.
Just watched my lovely mutt Emma pin a grouse. She is literally vibrating as I trudge the best part of 100 yds. through the most trying of cover, ( a logging road)! As I approach the area, fully expecting said grouse to exit stage X I can see it screwing around on the ground, undecided in its next move!
And then, the flush! Straight at me as I empty both barrels to no good effect! A rookie mistake I know, I know.
