How tight should toilet flange be?

Really quick question.

Bathroom remodel. My ABS 3" sewer pipe was cut just below the finished floor. I am installing a toilet flange with a metal ring that goes on the outside of the sewer pipe.

It seems I can only push it on maybe an inch before it gets super tight. Won't go all the way down. Are these tapered?

Do I need to cut the pipe down more or will the glue make it goe down further?

I assume dry fitting will be restrictive, but I'd hate to glue it and find it won't seat flush to the floor!
