I finally got out and shot the new Hevi-Shot choke tube. I was shooting from 40 yards and measuring the pellets in an 11" circle. I shot my best group using the Remington Hevi-shot 3" #6. I put 177 pellets in the 11" circle. The next best was the Hevi-shot 3 1/2 #6, with 158 pellets in the 11" circle. I was initially dissapointed with the results, until I read an article in the April issue of Outdoor Life. The article compared the test results of the Hevi-shot choke with several other brands of choke tubes using different loads. The test results were consistent with the results that I exprerienced, with the exception that they performed the test at 40 yards measuring the pellets in a 12" circle instead of 11". If I counted the pellets around the perimeter of the circle the results would have been pretty much the same. The test results from Outdoor Life showed the Hevi-shot combo out performed the others tested. I haven't tested the other chokes that they were using, but I can say that there test results were consistent with mine and that the Hevi-shot choke definitely out performs the Jellyhead that I wanted to replace.
