I am not familiar with Ace. The Brux cut rifle barrels are simply the smoothest I have ever seen, and they make a sheet show of some of the other top-name cut rifle brands.
You can trust Krieger's close second, and their customer service, before, and after the sale. I have one Muller, 7T 223, jeez, what a shooter, not a copper fouler either.
Customer service after the sale is a huge issue with me, performance, not a line of BS.
Have your gunsmith bore scope your barrel before chambering. I bore scope mine before sending them to the gunsmith, learned the hard way, several times. It is common practice for a lot of gunsmiths to chamber a customer's barrel "as is". If there are issues with the barrel sent to him, that is on the customer.
