XX full hastings choke for rem 20ga?

[Kyfoster11]

Has anyone got any experience with this choke?  I had one given to me for a rem 870 20 ga. and thought about trying it.  If so tell me what shells you are using and what patterns you are getting.
thanks

Gotta tell us more about it, is it an extended turkey choke or is it a flush fit choke? Whats the constriction on it?

[Kyfoster11]

It is an extended tube lead only choke.  Not sure on the constriction (it doesnt say anything on it). 
thanks

All I can tell you is to use the Federal HW #7s or if you are lead only use the federal FC #6s.
