I just got my 30 cal 700 mm x barrel on my impact, and have got to do some shooting . I must say I am very impressed so far . Hammer on max valve limiter on 4 reg at 140 bar. I get the 45 grainers moving at 920 fps 50 grainers at 875( 84-85 foot lbs). The 45 grainers are a little tighter groups. It is stacking them in one hole at 50 yards. I will take it out to 100 yards and beyond later. The standard dev is a lot better than my 25 cal regular smooth twist and it is more accurate ( 10 shot group es 2 sd 8 ). Has more of a kick as well .
What are you guys experience with your x barrels ? What speed have you found to be the most accurate ?
