Very interesting, I see wolf spring sells EX hammer springs all the way up to 26lb. If the weight on the end of the barrel was a huge problem wouldn't people running suppressors also go through barrel faster? Which they probably don't go through the round count most of the people on here do.
I also think that running a 26lb hammer spring would equal more muzzle rise but couldn't you just over come that by adding more gas to the comp.
What we need is someone shooting with a slow mo camera to test both ends of the spectrum like a 13lb hammer spring VS a 26lb or something.
