Any time you can shoot same or similar bullet weights from 2 different calibers the smaller caliber always wins. You can shoot 200-220 gr bullets from a 30 caliber about 50-100 fps slower at the muzzle, but the better BC's of the 30's will catch up and be same speed or faster somewhere between 50-200 yards down range. It just depends on the exact load. At the same weight a 30 caliber bullet will be longer than a 33 and give deeper penetration at any range. The difference in diameter between 30 and 33 just isn't enough to matter.
If you go to 250 gr or heavier bullets the 33's start to show some advantage.
