Kick's makes a quality tube, as does Rhino and some others..

50 to 55 yards is extreme long range for turkey shooting..There are gun/load/choke combos that will provide a sure kill pattern at that range, but they tend to be the exeption rather than the rule...40 -45 yards is a much more realistic sure kill range limit for most guns...

If I wanted an extreme long range turkey gun ( andI DON'T) I would look into some of the heavier than lead non toxics like hevishot or Nitro loads...Keep in mind these loads require special choke tubes and may not be safe to fire in choke tubes designed for lead shot..

Also, keep in mind that there are tradeoffs for extreme long range performance... If you find a choke/load combo that patterns tight enough for sure kills at 50-55 yards, that pattern is going to be VERY small at closer, more normal ranges, making it very easy to miss a bird that sneaks in and gets TOO close.. Good luck and be careful out there...
