CZ457 VPT 24" bbl. Put a BScar 25 MOA rail on it, then topped with Athlon 6-24x50 Midas TAC in TPS TSR low rings. Trigger on this one has a black finish, only one I've seen that wasn't the same shiny silver finish as my American & MTR. Got it adjusted to just under 1lb - very decent trigger, just like the other 457 triggers I've tried. Hoping to get the shiny aluminum bolt knob CeraKoted today - have turned another one just like it for my American, and it really does make running the 60* lift bolt easier.
When I began cleaning factory preservative oil & crud out of the bbl prior to shooting, I kept getting black patches, so went in with just a few passes with a bronze brush, which resulted in a bunch more black patches. Finally dry-patched & took a look with a Hawkeye borescope - and found an area about 1-1/2" long, 1" from the leade of considerable leading that looked like vaporized lead covering the whole bore as opposed to lead streaks on the lands like you might normally see. I got out a new bore brush and attacked the lead with it - took some time, but got rid of all of it eventually. The bore looked a little rough under that leading, but I've put about 200rds downrange with it since, and haven't seen any more lead fouling. While I'm not exactly blown away with the 50yd accuracy, it does show potential. The chickens in the upper left with the line drawn around them were shot with another rifle on a different day - just too cheap to throw the target away and start with a fresh one...lol
