Benelli Crio Choke for 250/250 Pattern

[Glades]

I just purchased a Benelli Montefeltro Compact (24" barrel, Short LOP) that has the Benelli Crio+ choke system. Basically identical to the M2 20ga. I will be shooting Apex 3" 1-5/8oz #9s through it, and running a FF3 on a Sumtoy mount.

I am looking for a choke that will give me an evenly distributed pattern at 40 yards, around 250/250 distribution. Want to avoid a super hot core, and rather have a more forgiving pattern.

For those of you with experience with the M2/Montefeltro 20ga, and have put this load on paper, what do you recommend?

I would start with the 570 or 575 I seen some 580 do very good also.

Try your factory full choke. That's what I used in my 24" M2.

I have gotten 250/250 patterns with the Carlson .575 in several 20 gauges of different makes most recently with a Stoeger M3020 but I have never tried it in a Benelli. I usually run that choke when I hunt with a gun that has Iron Sights. I usually go a little tighter with a Red Dot.

575 Carlsons seems very popular across the board. Unfortunately Carlsons doesn't make one for Crio +. They make 555, 565 and 580. Trulock doesn't make a 575 either.

Might need to try a 580 carlsons or 570 trulock.

I have a .575 Trulock for my 20g. Franchi/Benelli (mobil choke). Carlson will make a Crio choke for you if you call them. Trulock probably will too.
