Difference in 20 Gauge STS and Gunclubs

[Double Lab]

If there is I've never noticed it Ed. The Hodgdon manual lists them as the same and if you cut one of each into a cross section they are internally identical. I use the crimp as a guideline. If the crimps come out good then I'm satisfied. I load them both in 12 and 20 with the same recipe, use low pressure, light loads and have had good results.

Ya, I agree with both Daryl and Paul. I have loaded them both the same and have noticed no difference.
