Great looking rifle and sounds like you have a real shooter. I also have a 20" Shilen and it's a keeper. Just curious at what elevation your shooting. I've considered a Vortex 2.5-10X32 Vortex for my 16" Faxon. I assume your Vortex scope had enough internal adjustment to get to 1000 yards (34 MOA)? I know your swapping scopes so do you feel you need more than 10 power magnification at 1000 yards. I put a 20 MOA mount on my Shilen but I usually shoot at 350'-400' ASL. Decisions decisions but part of the fun.
My go to load for my Shilen is 31.0 grains CFE with CCI 450 primers in Lapua cases at 2.255 COAL with 123 Nosler CC. This load is MOA or better out to 880 yards for me. This load matches or exceeds the velocity I get for factory Hornady 123 grain A-Max depending on lot number.
