I goofed in the editing, turn on your captions. Important info.
Testing NINE different factory loads in my WWSD build with the barrel HOT. Some expected and some unexpected results. Let me repeat, the barrel was hotter than I would normally let it run, intentionally. This is not a test of ideal results but a test of the barrel when stressed, not to mention dirty. I don't think the finished video really made that clear.
All rounds were from the bench with a rest in front and a beanbag in the back. The wind was not as dramatic as the video makes it look. Scope was the Primary Arms Glx 2.5-10x.
All rounds went in straight, the odd look on video is due to the angle and flapping paper.

A similar setup with a different upper is consistently at or just below 1MOA with good ammo, but not with a barrel hot enough to fry eggs. Honestly, I was impressed by the Tula results. The group looks worse than it really is.
