I have ordered a box of Nosler Partition HP .451-260grain and a package of MMP HPH24 sabots. I also ordered some Barnes Expanders. We'll see what happends. I'll keep you posted.
Why not have your son shoot the load in (varying the load up or down until he get an excellent group) and then you adjust it to your eyes?As for the Noslers or the Barnes, both are excellent bullets whichever groups the best in your rifle go with them. I tested 8 differentbullets in my Savage only 2 of them groupedexcellent, results are here:

You (or your son)may have to experiment with with different sabots, and you want it to load tight but not impossible, I find the crushed rib sabot works in my Knight and TC Omega, but it is too loose with Noslers in my Savage, with .452 bullets the MMP 12 work well in the Savage.
