A chronograph will inform you whether or not, adding powder is accomplishing anything. Myself, i 'know' that 120g of powder gives more energy to bullets shot from my rifle than 100g of powder. My rifle also shoots bullets faster over 140g of powder than, 120g.
This season, my load will be 270g Deep Curl, 90g Blackhorn powder, crush rib sabot, and W209 primer.
