For all of you wondering about Criterion barrel quality.
I shot my last short range BR match yesterday and shot the best score to date(4th season) using a barrel that went over 1300 rounds during the match. This is a 243 match barrel polished SS 26" 1:8 twist shooting 105gr. Bergers at 2890 fps. I thought this barrel was done but the new 6br isn't here yet so I had to use it, now I am not so sure, it is getting bore scoped next week and if still relatively good it will be re chambered to 6br.
For those who care I shot a 247 out of 250 at 100 as stated my best to date. If I wasn't so thick headed I would have clicked up 2 clicks and shot a possible 249 after I dropped a point on the 3rd relay.
So in my opinion Criterion are good to go when matched and tested for the bullet and powder you want to use.
