Beretta A303 Choke Reccomendations

[Loyalist84]

Hi all - I recently switched my BPS to full-time deer gun detail and picked up a nice Beretta semi-auto threaded for Mobil chokes to devote to turkey hunting full time - the only problem is, I have no idea what choke to look at, and it doesn't seem like this model has seen much use in the turkey woods. Should be the same as a Browning B-80, though. Anyone have experience with this gun?

Don't have a 303, but my Beretta 686 Ultralight shoots lights out with TSS 9 handloads and a Sumtoy .675 waterfowl tube - 345/10" @ 40 with a 1&5/8 oz load. They should have similar bores.
