i prefer loose also, my reason is that on my 209X50 encore barrel with the shape of the breech plug (concave) i was very uncomfortable with my bullet seating procedure, once i loaded it and the ramrod went 1/8-1/4 past my mark, i took the breech plug out and there was a crushed pellet, my accuracy is better with loose also
Plus if you crush them at all your accuracy will suffer big time.
i was also worried aboutpowder to bullet and air around the chrage increasing pressure, may or may not have been an issue, i just know my gun shoots much better with loose
