They may be similar internally, but I've had more problems with the 04 bullets than any other LPR that I've come across, psycho ballistics and dye excluded.
Bullet LPR's seem to creep.. a lot. Though the Tickler is nice, for the money you can have better. AKA, Palmer, ST, Eclipse, and Belsales are probably the upper tier of LPRs. Good luck.
