"Took my newly barreled Savage 12LR .223 out to the range yesterday to see which load it likes. Loaded Varget, H4895, 8208 and Benchmark with two different seating depths and three brands of bullets each. I was very disappointed with the first three powders - not even one MOA.
just a guess.........
with different burn rates of powders you used .... maybe the barrel twist an bullet weight had worked better with just the one... not mentioned....
