PG .555 or .570 for Nitro 7's??

Not sure of the bore diameter differences in the beretta 390 and the Rem 1187.  The only way to know for sure the difference between the two chokes in that particular gun is to shoot both.  I can only tell you that the beretta with the 26" in barrel shoots incredible with the . 570 on 6's and 7's.

I have a 26" pipe on my 1187. Would there be a difference with the 555 if your shooting hevi-shot 7`s??

If its a pg .570 then yes.  Other chokes at .555 perform differently than a pg .555.  I get about the same 10" numbers from a ic .555 that i get with a pg.570.  The pg .570 has better 20" numbers in my 26"
