It may be,I know I looked at one of the performance shop sbe3 with the pistol grip like I have on my gun,it had the same .655 choke in it as I have got....I have an old nova that I have a Hastings .640 in,and it says lead shot only wrote on the choke,I shoot the old Winchester supremes 3 1/2 inch # 5 in it and for regular lead it shoots a really good pattern,I hunted over twenty years with that combo until I got this sbe2...I didn't need the new gun as that nova always killed them as far as I will ever shoot at a turkey,but I just always wanted a sbe2 with that steady grip,and finally just got me one...I love it,it so much thinner than that nova,And that steady grip is the cats meow for turkey,lol
