Of particular interest was Semi's post re: PRB just touching his GOEX. I use 777 2f but assume the same hold true.
Be careful of that assumption
3seasons. Triple Seven and GOEX have different burning characteristics and may not behave the same at all.
Even with GOEX this may be one of those things that are gun specific and one gun may like a little more compression than another. I pointed out my finding just to show that this is something worth experimenting with to see if it makes a difference in your gun. Consistency is the key regardless of what level of compression is used.
