Contradictory Issues?
#5
I am 18 clicks out on the gas block and according to my directions that is full open.

Bullet is the BT target tangent ogive (24428). I never tried to find the lands but used mag length as my starting point. 1.588" CBTO was my max length and best accuracy comes between 1.570" and 1.561" CBTO measured with SAC modular headspace body/insert. Seems like I would always have a flyer or two in every group so I was question brass. Typically I do not crimp. I tried that in one reloading session but I am not convinced it did anything. I was concerned about damaging the bullet since there is not a cannelure. Maybe I need to revisit the crimp?

No ladder charge per se with the Alpha brass. I did try multiple charge weights of 27.2, 27.5, 27.8, 28.1, 28.4, 28.7, and 29.0 gn but all marked up the head and some did not lock the BCG.

I took a quick peek at the website and then reached out to Compass Lake to see if they know what they drilled. They dimpled the barrel for the SA gas block so I would think the alignment is good and hopefully the diameter is correct. Customer service email indicated Paul Ross opened his own company and they are referring customers there.
