PATTERNING & IMPORTANT CHOKE TUBE INFORMATION

Carlson’s Choke Tubes are made from the finest corrosion-resistant 17-4 PH stainless steel available. Most factory choke tubes are made of lessor stainless steel, which equates to a choke that won’t hold up to most steel shot loads or heavy buffered shotshells. Steel shot patterns tighter than lead shot. Generally speaking, you will want to use a more
open choke when shooting steel shot than you would with lead.

USE THE FOLLOWING RULE:

• Cylinder Choke with Lead Shot = Improved Cylinder Choke with Steel
• Improved Cylinder Choke with Lead Shot = Modified Choke with Steel
• Modified Choke with Lead Shot = Full Choke with Steel

Steel shot, up to and including BB’s, may be shot through all of Carlson’s flush and extended chokes, up to “Full” constriction.

Our Extended Steel Shot and Sporting Clays chokes pattern 10-15% better than standard choke tubes when using steel or lead shot. These improved patterns are attributed to a longer parallel section within the choke tube. Our Extended Choke Tubes are much easier to remove and insert, and each Choke Tube features an engraved head for easy identification.

Never use BBB, T, or F shot through any flush mount choke tighter than modified. The best patterns with those shot sizes will be achieved with extended chokes, up to “Full” choke. DO NOT Shoot fast steel (1450 FPS and faster) shotshells through any flush-mounted choke tighter than “Modified” or Extended Choke tighter than “Improved Modified”.

Hevi-Shot, Bismuth, Tungsten, High Density, and similar shot may be used through our tighter chokes as tight as “Extra Full”. For waterfowl hunting and long range shooting, we have found that Hevi-Shot shotshells perform best in tighter choke constrictions up to “Extra Full”.

Carlson’s Turkey Choke Tubes have tighter constrictions and pattern better than standard choke tubes. NEVER shoot steel shot through an Extended Turkey Choke Tube. Hevi-Shot, Lead, Copper, Nickel, Bismuth, High Density, and Tungsten Polymer Shot can all be used through CARLSON’S EXTENDED TURKEY CHOKES. We have had best pattern performance with #4's, #5's, and #6's. Larger shot sizes may be used but their use generally results in more “flyers” in your pattern.

Most importantly, pattern your shotgun with the shotshell and choke tube your are going to hunt with – BEFORE going into the field. You take the time to sight-in your favorite rifle and scope, do the same with your shotguns for a more successful hunt!
