barrel porting?

[munky]

I'm shooting a Browning BPS with full rifle barrel, love the way it shoots and that its bulls eye every time. "The question is" would porting effect the performance, speed, accuracy?

It 'could' change the POI.

It 'could' change the velocity (lower it).

It 'could' change the accuracy but possibly not.
