This oil in the 20w-50 variant is what my engine builder recommended and I ran it for around 8k miles with interesting results. Link for UOA here. I was going to run an VOA on the 20w-50 to debunk some sodium concerns but I think this covers it.
Thanks for the VOA

Depending on the volume you shoot, TargetSportsUsa.com has free shipping with their prime membership. You can also see if a local gun store is willing to order a few boxes for you
