Thats what happened with my omega. I put in 100g of BH and it gave perfect groups at 100 yards and at 150 yards.
So here is another question. Do you experiment with 110g if you are doing great with 100g? Would you feel you are wasting powder?
I just think I am saving money by not going up. Plus, less recoil.
What would be the advantage of upping a load if lets say....your MZ shot good with 90g?
