I'm new to this forum and just as green on choke tubes.I just traded for a used Mossberg 835.3 1/2 " chamber w/ ported barrel.Included in the trade was a Hi-Viz Long Spur choke tube w/ opening of .705 It is also ported.My question is: Is it safe to shoot a ported choke in a ported barrel? Would this be TOO much porting and a waste of time to shoot this ported choke tube? Thanks for your time. TLK
