I hope I don't have to slow my 32s down to 3700.. I bought a 22 inch barrel for speed.. I wanted to go at least 3700 with 39s and my 35 at 3800+ and the 32s just under 4000.. If wanted to go slower I would of bought a 18 to 20 inch barrel.. The 204 is about speed and shooting flat is the reason I purchased them.. I will try to find a node around 3700 for the 40 grainers..
