Home Forums Hunting & Shooting Rimfires CZ 457 American

After reading another tread on a different forum I would like to correct what I posted above “ check the bolt bottom where the serial number is engraved into it, mine was very rough and I had to polish it to remove that grittiness out of the bolt” When I got the gun after playing with it for awhile, I stripped it, cleaned, and lightly oiled it, the bolt was gritty. Looking at a post on line it told about the roughness of the serial number and that it drug on the bolt carrier. I polished the bottom of the bolt and the top of the bolt carrier to smooth them out. I also noticed the bolt had some lines and marks around it so I polished it with some 2000 grit and finished it off with a red crocus cloth, still had the marks and lines but the whole bolt felt slick. Today after posting this I’ve gone back and taking a black sharpie to the bolt, I blacken the front of it all the way back to the bolt and then reinstalled it, cocking and un-cocking it about 20 times. What I found is the front of the bolt body touches the action in multiple places around its circumference…. I couldn’t find the bolt touching the bottom where the serial number is engraved but I’ve already polished mine, so maybe it might drag but I didn’t see any evidence of it. I still would advise polishing this area of the bolt as it’s rough enough to catch any cleaning rags you’d use to wipe it down with, but I think I probably got more of the grittiness out by lightly polishing the rest of the bolt. I used to use a small oil lamp to blacken the metal but the Sharpie test works good and is easier to clean up with a little rubbing alcohol, try it for yourself and see what you think, as always YMMV.

Well, at least you can use that sob as a boat paddle, when you go out fishing..

That's a centerfire rifle, not a 457. JB probably got confused, when posting the pic.

Came across another issue with the CZ457. Yesterday I was playing with the trigger again......... I know, I know, but I just can't help it Anyway, I set the pull weight to 1lb. even thinking I might like that. Put it all back in the stock and as I was tightening the action screws I lightly snugged up the front and rear screws, set my torque driver to 20in.lbs. rear and 25 for the front. When tightening the front I noticed action movement. Well that's always a sign of poor bedding, but then I checked the trigger pull and now it breaks at 11oz., so either the trigger housing is touching somewhere or the bedding sucks. I'll check both but I'm betting on the bedding.
Oh well, I was going to replace the pillars and bed the action anyway. No biggy.

Here it is:



During the Great Obama Rimfire Shortage I found some of this Armscor hollow-point LR ammo, and decided to try a couple boxes. It shot so well I then bought a few bricks of the same lot. Dunno if other lots group as well, but this batch has sent a lot of ground squirrels to another world....

Glass bedding is always the answer as you know. Pillars are great for keeping the torque from compressing the stock, but it's the glass bedding the accounts for the accuracy and allows for removal of the barrel action and then reinstalling it without loosing your poi.
Next up is going to be drilling out the plastic pillars ( why did they use plastic), installing aluminum pillars, (I've used brass pillars at times), then glass bedding the action. Then I'll tackle the mud.

Nice shooting Mule Deer. How muddy was your stock?

Hard to beat that. That is the varmint version, isn't it? Nice rifle.

Yeah, it's the varmint version with the 20.5" barrel. And as mentioned earlier, I bought it next-to-new new off the Campfire Classifieds, at a very good price!

BSA
There's a 457 for sale right here in classifieds. Very decent price.

That even tempted me, but glad drover picked it up. Hope he'll give us a report on it.
