All this talk of "game gun" suitable chokes seems somewhat moot to me. The gun has 30" and 40" barrels! "Game gun" it ain't! (IMO, of course). He didn't mention the weight, but I'll bet it isn't a 6lb 'magic wand'. So, why try to make it one by choking it for such work? If that were the tact, why not chop the barrels down to 26", backbore it to quicken the swing, add a 2 inch long "green worm" to the rib, a much favored middle bead, adjustable comb, aluminum adjustable buttplate with a purple recoil pad, sling swivels ....
So, about chokes...
I once bought a 28" Browning BSS 20g with F/M chokes. I took it out the day I got it at the range and shot 3 rounds of skeet with it. I shot 25 the first and third rounds and a 23 the middle round. Now I don't shoot that many 25s, maybe once a year or so, mainly because I don't shoot much skeet and some because I don't keep my head in the game and start 'playing around'. I also took that gun to a sporting clays shoot and won a buckle for sub-gauge class up at Moore-n-Moore. I shot so well with it that I wanted to use it for hunting as well and thought I should open the chokes to M/IC. I never got around to it.
Later, I bought a BSS 20g 26" gun with M/IC. I now have my poorman's 2 bbl set.
The last couple seasons in SD, I used the F/M 28" gun to take a good share of my total take. I'm sure glad I didn't mess with the chokes, looking back. The 26" gun gets a lot of action on quail and chukar where the shots are close and the hilly country makes a 26" gun much more desireable (for me, with my long arms and average height).
