Am I off or does it seem that 42.0 grains of H4350 under the 120TTSX seems light? My 130 VLD load is 43.5 H4350.
Remember that a monolithc bullet builds a lot more pressure than a lead core bullet. therefore the reason for the lighter powder loads in the manual. Barnes bullets are grooved to relieve this pressure. Also keep in mind that due to pressure buildup, seating should move away from the lands rather than closer to the lands
