I could be wrong and I'm sure powder choice will make a difference but I think you might find that the 6 mm bore size may allow you to push a 55 or 58 grain faster than the smaller 22 caliber bore size especially in a shorter tube. H322 will push a 58 / 3700 without being over pressured. The 6mm also gives you the option of the 70 and 75 grain bullets that will work in the same 10 twist that the 55 amd 58s will like. I also think you will find that at night hunting distances which Max at 300 or 350 yards there won't be more than 1 inch to 1 and 1/2 in trajectory difference with the heavier bullet vs. the light pills.
