Klikboom, I have a Savage Model 12 VLP chambered in 300WSM. I haven't yet loaded for the 180AB but that is next on my list. I have a sweet load for a Barnes TTSX 168 using RL17 and am working up a load with a 210 Berger using H4831SC (not yet range tested). For the 180AB, The Nosler Reloading Guide 7 lists IMR4350 starting at 60 grains (2736 fps) and a MAX of 64 grains (2942 fps). Velocities are from a 24" 1-10 twist, 4 groove HS Precision barrel. The Nosler data is a good place to start. Nosler lists Hybrid 100V as the most accurate power tested with the 180AB. Hybrid 100V is readily available right now. It's on the shelf everytime I stop by Sportsman's Warehouse. You might consider running a ladder test with both 4350 and Hybrid 100V. Accubonds typically shoot best with a 0.010 to 0.020 jump off the lands, but there are always be exceptions to this so if you don't get the results you want prepare to start experimenting. Hope this helps. CaNINE
