Turkey Choke Tube Constriction question.

[tpaturkeyguy]

I have a stoeger M2000 and the last couple years have been shooting the super full choke that came with it which has a constriction of .660. I have just purchased a Kicks Gobblin Thunder turkey choke with a constriction of .665. I am wondering if anyone knows what I can expect from the difference in these two constrictions. Which is the tighter constriction between the Kicks @ .665 or the Beretta mobile choke (which is what comes with the gun) @ .660?

Looking forward to field testing, just wanting any help I can get.

The smaller the number, the tighter the bore.
.660 is tighter than .665


My benelli has a bore diameter of .720 and if I use a choke tube with a .06 constriction , i will end up with .660 exit diameter.

if i use a choke tube with a .055 constriction, (not quite as tight as the previous ) i will end up with an exit diameter
of .665

Both of these are very tight chokes


*Actually my benelli bore is .723 but this makes the math a little easier

Thanks....

Also wondering what combinations people have found to pattern best. Speaking with one individual, they indicated the barrle of the M2000 and SBE and most Baretta and Benelli semi-autos would be the same as the Stoeger, the major difference in all these lies in the inner workings of the guns nott he barrel. With that being said it should seem that the choke ammo combo that works in a SBE should be similar exiting my barrel. I am shooting 24" barrel.

I shoot a SBE 12 ga and a M2 20 ga for turkey hunting. For the 12 ga , I get good patterns shoot 685 with good old federal #5 's Pretty much anything shoots well. I dont really like super tight patterns and I dont really care for the flite control. for some reason, the flite control seems erratic for me. tight centers , but the entire pattern seems to drift from shot to shot.

For my 20 gauge, I do shoot the flite control, #7s HW and I get very good results with factory full choke.

I have tried lots and lots of combinations of loads and chokes for both guns.

tpaturkeyguy, HH is correct and I would add that the .680, .670 and .660 (in those ranges as every manufacturer seems to be different) constrictions ar the ones most often used in turkey hunting. The two biggest variables in finding the right combination are the shotshell and the shooter! That is why you need to get a box of each shell you would like to use and see what patterns best. Try the less expensive shells first as I have had great pattens through my chokes (you can check a few patterns on the BlackBore website).

Mark,

Thanks for the reply. I checked out the website the the turley chokes indeed produce a very good pattern with the Rem Nitros which is what is my preferred choice in ammo.

Thanks for looking, tpaturkeyguy! Please note that I used the .680 constriction for those two patterns. A lot of hunters use even less such as .660 constriction, but I found it gave too tight a pattern with some loads. It's that balance of the concentration of the shot and the distance to the turkey where one has to decide on which choke constriction to use.

Very impressive website blackborechokes. And, those are some awesome looking patterns at 40 yrds. i love the concept and design and hope you have a lot of success. it must be fun developing new ideas and designs.
I am intrigued that yo have good results with the flitecontrol. i guess the whole idea behind that wadding is
to strip away the wadding as cleanly as possible. Looks like your chokes assist that process.

HH,
Thank you for the great comments! Yes, I was surprised that the results were good using the Fed flitecontrol loads.

I have exceptional good patterns with a .665 Trulok choke, 3.5" Hevi-13 #6 shot.....Stoeger M3500 and Benelli SuperNova. You wont be disappointed at a measured 40yds.
