About two months ago I ordered a barrel from McGowen. It's a 30", stainless in 220 Swift with a 5-groove, 7.7" twist rifling. I was told it be every minute of 4 months. Well, I got a shipping notice that it's on its way. Classic example of under promise, over deliver.

I'm really curious to see how the 7.7 twist, 5-groove barrel works. It's the only caliber (.224) that McGowen offers in an odd number of rifling grooves (5) or fractional rifling rate (7.7).
