RE: Indian Creek Choke tube
I know a guy here who just got one. He said it didn't do so well with Hevi 13 versus Win X-tended especially in #5 shot. He's shooting a 870 Supermag in 3 1/2 inch. He has more of an issue with the Hevi-13 than the choke. It defintley improved his patterns over the factory extra full and undertaker.
BiggerHD shot doesn't seem to like the smaller constrictions. I'd like to try those Nitro triplex with a tighter chokelike the Indian Creekbut anything with #7 in it is illegal here for turkey.
