most barrel fronts are HUGE. If there's a place in a barrel where a scratch won't matter - that's it. The ball shouldn't really be making contact with that portion of the barrel.

no kidding I'll get a pic of my empire 18 inch front, I think they had a tool collision on this one and just sold it as a second (the reason I got a whole barrel for 15 dollars shipped brand new), its really ugly in the front.

Agreed! Great Video

I have a suggestion in regards to future testing on the effects of porting (volume, efficiency, etc). If possible, isolate the bore types (stepped vs non-stepped). Since a stepped bore barrel will allow air and sound, to slip by the ball as the ball moves through the front. While an underbored barrel will force the air to exit through the porting all the way until the ball leaves the barrel.


we've never found an optimal test arrangement for porting testing. we really need 3 or 4 identical barrels - from non to heavily ported. and then we need a second set that's either stepped or two-piece.

No company offers that - they mostly just design one porting pattern and go with that. It's prob a custom thing - so if anyone knows anyone who's making custom barrels - let us know.

I know for a fact that Stiffi is really nice about making custom barrels. You can call them up and ask them to make practically any bore size at any length with stepping or whatever. I'm sure they could have some fun with the porting if you asked them to.
