pigeonblasterian Posted April 26, 2013 Report Share Posted April 26, 2013 This afternoon decided to change the springs in 17hmr and 22lr.I had slackened them off as much as i could with the factory spring fitted but just wanted to lighten the pull on the trigger a little more so i bought two Yodave kits. I fitted the second lightest spring out of each kit into each rifle. I never fitted any shims as i could not feel any creep on the trigger. I should have changed the springs ages ago as the difference was apparent straight away. The pull is much easier and will take a bit of getting used too. I hardly put any pressure on the triggers and you get a nice clean pull. Tried the 17hmr out this afternoon and got three rabbits. Took the 22lr out tonight for an hour and got one rabbit but rain stopped the shooting. Will have to set the targets out again and see if it will make any difference.

scouser Posted April 26, 2013 Report Share Posted April 26, 2013 it amazers me how a simple spring can make so much differance, i used to get the brooks from south yorkshire, but now they do there own which are just as good. . i even tried the sping from a BIRO, it worked but was to light.

Rimfireboy Posted April 29, 2013 Report Share Posted April 29, 2013 They work well but you've got to be careful, I wouldn't use biro springs, could be dangerous just to save a bob or two. Quote Link to comment Share on other sites More sharing options...
mbga9pgf Posted May 1, 2013 Report Share Posted May 1, 2013 How easy is this to do on a cz452 .22lr? Quote Link to comment Share on other sites More sharing options...

mbga9pgf Posted May 6, 2013 Report Share Posted May 6, 2013 Thanks for the link. May invest in one of the kits available on fleabay http://www.ebay.co.uk/itm/CZ-452-455-and-BRNO-No-2-4-and-5-trigger-kit-/160800484012?pt=LH_DefaultDomain_2&hash=item257074aaac Pretty happy with the 452, but the trigger is waay too heavy for me and I think is affecting my accuracy. I take it the metal tubes in the kit affect how far the trigger pulls? Shame the cz rifles don't come with an adjustable bolt like my good old BSA super sport.... Ah well, looks easy enough to do. Does the pin come out easily or do you have to coax it with the punch? Quote Link to comment Share on other sites More sharing options...
pigeonblasterian Posted May 6, 2013 Author Report Share Posted May 6, 2013 I only took out the uncrimped pin so that i could replace the spring.I never had a punch small enough to knock the pin out so i knocked it level first.Then used a pop rivet to knock it out.
