Nice turkey, and great story. Like you I would have been very nervous about him gobbling up every hen in the county. Tells me the hens aren't ready to be courted yet and the gobblers will have to go find 'em. Nice situation for you while it lasts.
That supermag is also a nice looking gun. I like the way they extended the rear of the stock making it easier to hold up on your knee while sitting.
Not to nit pic, but I would age him more likely as a 2-year bird with 3/4" spurs. Obviously I can't see them in the picture though.
