Ok, I have some questions about echo goose inserts. I just ordered some and I need some information. 1. How big does the hole need to be for the insert? 2. How long should the barrel be for the insert? I figured the barrel would need to be about 2 7/8" to 3 1/4" cause thats what I used for my other barrels and i figured the barrel hole would need to be 3/4". Any help would be appreciated cause I have never used echo inserts before and I have a couple people asking for them.
Thanks
