SAAMI Grendel Barrel Makers?

[VASCAR2]

The Saami chambers are not all created equal, I've had numerous barrels that have had problems with Hornady ammo because of the ogive shape, not sure whose fault that is. If you hand load, no issues.

Just speculation on my part, if a reamer is worn and out of spec may not cut as deep on CNC without adding depth to the cut (probably doesn’t happen in mass production). Attention to detail is critical on an accurate barrel. When you buy a custom barrel you expect attention to detail and tight tolerences. On mass produced rack grade barrels out of spec barrels can slip through. Some companies only inspect a percentage of a production run. Some companies do a better job of checking each step of production to ensure every barrel is in spec. How a manufacture can keep the lowest price point with high quality with tight tolerances is a challenge.
