My 17 hasn’t had a kernel of anything other than CFE223 in years. 25gr is the moneymaker in mine with the 25gr HPs. 26gr under the 20Vmax shoots lights out and within an inch of the same POI. I don’t shoot colony varmints, so don’t shoot as many rounds as some of you guys but I never clean the bore on mine unless accuracy starts to slip. I don’t know if it’s the CFE or I just have a really good barrel but it cleans up in a pass or three and never really coppers up.
