choke question

[goblueM]

Hey all, I was pondering grabbing a new turkey choke before heading to the range to sight in my gun. I shoot a Benellie Montefeltro 12 ga. Been just using the standard full choke and #5 HeviShot the last 3 years, had no problems killing birds. However, hunting a later season this year and was thinking I might want some extra range just in case. Anybody got a reccommendation for a choke to get for the above-mentioned gun/shot combo?

And on top of that, a place to sight in near St. Paul? Usually have sighted in at my uncle's place but that's not an option this year

Truglow in mine has worked great to 60yds shot 1 bird that far and patterned it for the shot just in case 8-12 BB's in kill zone. Winchester supreme #4 is the shot I used with the same gun.
