Good stuff, a CZ 455 or the new 457 was next on my list for a rimfire trainer/ fun gun.. I will say tho, that while a rimfire trainer is awesome,cheap to shoot, good for learning wind, building positions, shooting a center-fire off barricades is still a different ballgame than shooting a rimfire (I dunno if your into matches or not) Ultimately, I think a .22 trainer and a .308 trainer would be pretty sick
