You have a 20.5 inch barrel. A speed of 3000+ is really good out of such a barrel. Think about driving with your car. You don't keep the revs at maximum when driving as it saves on wear and tear. Running at 65K psi puts extra stress on your lugs and cases. Rather use a longer barrel to get extra pace.
It all depends on your mission. Shooting 1 shell per year at a trophy elk at 600 yards vs match shooting every weekend.
Also short barrels have their place. You obviously haven't hunted hogs in Texas. Bailing out of a moving UTV is a lot easier with a short barreled gun in one hand, especially while holding a Bud Light in the other. As I said above (post 24), this gun is set up for a light load. I only ran the full charge weights during the initial load development.
Back to the main topic - OBT. This gun/load is case in point where the best accuracy did not occur at a recommended OBT node. But in full disclosure it was only one 3 shot group and maybe something else was going on.
Also velocity "node" derived from recommended OBT seems to be independent of barrel length.
