I've mainly been doing velocity ladders in my 416 lately. Today I tried out three different charge weights. Around 2600 fps still seems to be the sweet spot with the 350 grain mag tips. My newest 9.3x62 has only been loaded with the lighter bullets. Mainly the factory norma 232 gr ecostrike( shoots amazing ), and the 250 gr accubond which I've struggled with in this rifle. Today I loaded the 285 gr PPU RN with 65 gr of big game for 2,457 fps and 66 gr of big game for 2,498 fps. Here are the 416 groups.
