I have several Shaws and Criterions, many Mcgowen barrels not to mention a couple Shilen and a few others I cannot remember. I was waiting for a Criterion 243 barrel for an action I had ready when an E.R.Shaw in243 came up for sale on the site and I bought it was a good price, thinking I could play with it until my barrel came. I put it on my action after giving it a good cleaning took some loads to my range shot it in then shot a 5 shot group of .180 with 85 grain Sierra dropped down to some 65 grain sierras and put 5 in .142. Needless to say that barrel has found a home and I had to buy another action for the one coming.
