So brought my CM to the range. Run factory Remington 115gr, Everglades 147gr minor. Also tried Everglades 124gr and 147gr major. In stock springs, all run fine. No FTF or FTE, no issue whatsoever. 124/147 minor Is almost the same to my opinion. Got my Wolff springs 8,9, 10, 11, 12 lb springs. I’m gonna start at 8 lbs and work my way up.
