I think it depends on foam. The white foam I have from ben is light and less dense than MHA pink. Or maybe also the amount of hot glue used. Some people seem to use liquid nails, which allows for less gluing material. I just hoppered a BBBB, and that's my first hopper, and it works really well.
I'm using slugs with #8 washers, and they are pretty straight, but I haven't tested at long range, either. Right now MHA foam is a little tight for my PETG barrel, so I can't compare.
However, when using MHA foam and AMIOR style darts, I preferred my PAK D silicone tips with my 50mm dart length compared to normal or even 50mm AMIORs. When using my brassed bolt equipped EAT. Granted, the PAK D is a little thicker, but I dunno.
It could also be that springers and airguns work better with different kinds of dart tips.
I'm going off this thread, btw:

Some darts are coming in under a gram, and that's for total dart mass. I don't think that's enough.
