Well, that was pretty easy.....54.5 grains of H4350 with 180 grain accubonds, Fed210 primers and RP brass. 2680 FPS and currently shooting right at 1MOA out to 300 yards. ES of 18 with SD of 8.8. Gonna play with the seating depth a little but am plenty pleased with how it is shooting right now. I actually shot the last three rounds at 440 yards and range the gong all three times......with a 10X scope non the less. I would have no problems whacking a bear out to 300 with the current load. Rifle is a Winchester 670a. I topped it with a new leupold VX3 HD 2.5-10x40 with 1/4 MOA / CDS turrets. My understanding is this is basically a Winchester Model 70 that was made more affordable by having a hidden magazine....?? The barrel is not free floated on this rifle...so I would have been happy with 2MOA. Much to my surprise.....1 MOA, I'll take it.
We ended up loading 150 grain projectiles with 4350, shoots well in three guns that we tried and we are able to swap between various 150 gr bullets and still great results. Under 1 inch most of the time with inexpensive rifles.
56 gr IMR 4350. 180 grain Accubond or Partition.
