usually if you just have a few that are hard to seat you can take them out and clean with a VLD chamfer tool if you have one. or get a cheap primer pocket cleaner/reamer.

if you are buying a lot of mil spec once fired cases, then you might need to go with a higher volume setup like Dillon or RCBS swager. worth the money in the long run if you don't have a dillon 1050.
I would have assumed that remanfactured ammo would have the crimp removed during processing and they would not have "re crimped" the brass. too much working of the brass IMHO. but could just be some of the pockets are getting beat up somehow? it shouldn't take much pressure to seat a primer unless there's something not lined up in the press or pocket?
