Someone here on reddit made the claim that the TechT backblock can cause lower velocity on a cocker. So I decided to test that. I will say that 15 shots is not a large enough data set to make a definative conclusion IMO. I will say that I don't see enough difference to say there is any significant difference.
The cocker that I used was my Titanium Trilogy. (see post history for specs). I used a .688 8" insert with some ebay reballs.
Anyone happen to have a STEP file or STL file for an autococker IVG? I have some fun stuff I want to do, but not the knowledge to make the file with the needed accuracy.
