I am getting a new Criterion on an M1icon first of October. I am interested in seeing what it reads. I know a little about gun drilling and it is difficult. I know little about modern rifling and the accuracy they can hold. I do know I have a M1D that reads a MW of 3 close to 4 and it shoots great! I have another that has a Citadel barrel and reads a good 2.5 and it shoots no better. Obviously a 3 close to 4 is not good, I am surprised at how well it does shoot and expect it to go at any moment.

I will report on my new one. I would love to see a study of MW readings and 100 yard accuracy for series of rifles over time. Of course, who would do this and how much would it cost?

The long term barrel life test being done now by GCAicon is an interesting study.
