I've been reading alot of these " too tight" threads lately. I have a CVA eclipse that used for the first time 2 weeks ago and had no problems with loading anything. Shot 3 different types of sabots. Took a total of 10 shots w/out a problem. What I did notice though was that a small 1/4 of an inch buildup ring at the end of the barrel. This seemed to be from pushing in the plastic jackets. It did not effect the accuracy , only the amount of pressure I needed to load the last three shots. Once I cleaned , the ring was gone. The only prep work I did before shooting was cleaning the entire ML. Hope I dont run into the too tight issue
