A Few Pictures, Zeroing My .22Lr

[Deker 3,478]

 

 

Just standard trigger at the moment but will definitely look into it as I noticed a couple of shots where I "pulled off", and I knew it was off target before it got there, if that make sense.

 

Cheers...

Triggers get very personal.

My .22lr CZ Silhouette is original and fine, my last CZ WMR was fine, my latest CZ 452 HMR and WMR were awful and have had work. (my .22lr Magtech 7022 Semi has a trigger that feels like two pieces of sandpaper grating on each other and the pull lasts a fortnight, but the groups are remarkably good).

My lads CZ .22lr Style is not good to me but he loves it.

Don't rush into anything, get used to distances, ammo, quarry anatomy, terminal effect, scopes, reticles, etc., etc., before you go making wholesale changes to the gun!

ATB!

 

Advice appreciated Deker, I am learning fast. Firstly I have no other trigger to compare to but this one also feels like it takes ages. I feel as if I want it slightly lighter as when I'm on target I go for the squeeze and it takes just that little bit more than I feel it should. Its like such a minor thing that I feel might make a big difference. Give it a few minutes, it will wear smoother, and they are adjustable anyway on the 452 (to a small extent). Inexpensive trigger kits are available from several suppliers if you really find the need in time.

 

Getting used to distances and bullet drop, was pacing out a bit on my permission on Sunday.

The next thing I will find out for myself is if my poa changes when I adjust the scope focus (is that called parallax?). Nope, that's called poor engineering!

 

What is terminal effect? Different ammo will produce different results in different quarry/targets, Eley HP Subs don't expand well so they can punch straight through, produce a narrow wound channel and waste energy, Winchester and Magtech Subs have a BIG HP which expands well and produces a BIG wound channel, often delivering all its energy (staying in the quarry) and doing a lot of damage, CCI Segmented HP break up upon entry, etc. And we haven't even started on the .22lr HV ammo or shotshells etc!! Different ammo has different terminal effects and therefore differing benefits or problems, you need to find what works best for individual quarry and your rifle!

 

Cheers..

aye up

 

i would try some sk rounds made by lapua they don't hit as hard as Winchesters but are bloody accurate

here is a group with Winchesters

both at 50 metres

CZ 455 varmint 16"

struggling to get hold of lapuas so using Winchesters at the moment

just try different brands and stick to what works best

I bought a lot of winchesters in because they were local and cheap at the time, they do hit a little harder...but personally I prefer the accuracy and Eley were better in my cz by far. Just an opinion for you..

[Deker 3,478]

As above, you really need to try different ammo to see what works best for you, your barrel and quarry. We say it all the time, what is laser like in mine may spray shotgun patterns in yours or vice versa!

 

Even if you settle on one or two types of ammo now, try others again in the fullness of time as the barrel wears slightly, things can change!

Just to add to what Deker said, bullets that don't expand or fragment well are generally to be avoided against live quarry as the tendancy is for them to simply pass through in a narrow channel and wound the animal rather than kill. A pass through also increase the chance of a ricochet or you hitting someting unintentional beyond the target (hence why backstops are so important).

 

Solid points or poorly expanding ammunition is best suited to target practice.

 

Killing is generally done via shock and the larger the bullet or in the case of HV ammunition the hydrostatic shocking effect (where a large shockwave moves through the animal ahead of the bullet and over a much bigger area than the bullet and destroys tissue and blood vessels in its path), the more likely you are to induce a brain shock into the animal that causes its brain to shut down and it to instantly die. With ammunition that doesn't induce hydrostatic shock, its the wide expanse of bullet and the energy delivered ahead of it that bursts blood vessels and hopefully arteries causing the animals blood presure to drop and it to instantly be rendered unconscious whilst it undergoes a quick bleed out. With a non expanding or poorly expanding round, there's no significant hydrostatic shock effect usually as the energy transference is poor and the round can quite easily miss all important structures due to its surface area remaining small and simply pass through leaving the animal both conscious, alive and wounded.

Hi the trigger on my cz improved with use so don't rush out to get a kit like I did. Also don't be tempted to fit the lightest spring initially for field work, mine was dangerously light with it. I fitted the next strongest one, but even that one needed to be backed off on the adjustment as the trigger bedded in. Do a butt drop test to check that trigger is safe if you tinker. I would also check for any poi change when you change the mag on the scope, I found this on an old scope last week.

I've done pretty extensive tests with .22LR rimfire ammunition. Eley subsonics are the best round in terms of accuracy. I can't share the view they over penetrate either.

[DeerhoundLurcherMan 997]

I will leave the trigger as it is for now, how many rounds through the gun before the trigger beds in? (if its going to).

 

I'm just off to get some Eleys now....Ill post up a comparison between winchesters and eleys to see which my cz spits the best.

 

Cheers...

It may take a while to feel improvement, mine improved steadily over a year, though being an hmr I was not plinking too many rounds, If its not too your liking after you have sorted the best ammo with a few boxes through it, then a kit might be in order.
