T7 loose is more powerful volume to charge. However Pyrodex loose, Pyrodex pellets and T7 pellets are equal volume to charge (Ie: 100 = 100). My experience mirrors that of most others they shoot and behave similar.I don't use pellets due to loose being cheaper and easier to customize (I have only a couple loads that are = to 100gr volume, at that aren't ones I hunt with currently). I also weigh my charges now vs strictly volume making loose the only viable option for my loading practice.

I too use to think the pellets had applications in the field, however an empty/clean bottle neck cartridge works just fine as a speed loader/funnel.
