Patternmaster code black Duck choke tube velocitys..??

[guncrazy-sako85]

Hello all
i just bought a new patternmaster choke tube for my versa max and it says the best results are with shells less then 1550 fps.. does it hurt to shoot the faster stuff thru them like the Hypersonic which is 1700 fps. With this ruin my new code black duck choke tube?

Thanks

Any faster than 1550 ft/s and you are defeating the purpose of the choke as it is designed to retard the wad as it leaves the barrel allowing the shot to escape the wad undisturbed .

Basically like he said, over that fps, your patterns go to crap
