400 Holland and Holland is a ballistic twin, brass made by Qual cartridge or easily from 375 H&H. Uses easily found .411 bullets. Easy to load, very accurate and will crush anything you wish to.

My custom 700 (can't afford a "real" H&H) and the cartridge on far right is 400 with 400 gr Woodleigh (what H&H loads them with).
