What 457 barrel do you have now? What is wrong with it?Im looking to finally upgrade my CZ457 barrel but not up on the options.
Looking for a drop in barrel that will fire a reasonably broad selection of ammo from Norma Tac to Lapua and SK offerings.
What should I be looking at for brands and twist rate etc?
Its a 20 inch varmint barrel nothing wrong with it just looking at tweaking out accuracy and pushing more weight to the front so I've weighed up just adding more weights onto the chassis but by the time you add enough its into $100-200.What 457 barrel do you have now? What is wrong with it?
At some point I got myself a CZ457 MTR and shot it for a month or so, and then I got myself an IBI barrel that I then shot for over 6 months and kept my MTR barrel in a safe. Then I decided to flip back to the original MTR barrel and I was blown away how well the rifle would group with the original barrel... so now I am a huge believer in the CZ quality. more often than not, the ammo would make a lot more difference than swapping barrels.. also, a tuner is something I have on all my riflesIts a 20 inch varmint barrel nothing wrong with it just looking at tweaking out accuracy and pushing more weight to the front so I've weighed up just adding more weights onto the chassis but by the time you add enough its into $100-200.
I'll also possibly buy another cz457 and just switch out that barrel but its already a 20 week ordering time so may as well get it ordered.
I was going to ask the same question LOL. I started with a 455 Super Match; I bought a brand-new take-off CZUB Varmint Barrel at 20 1/2 ". I can't help but think had the original owner tried it, he would have kept it.What 457 barrel do you have now? What is wrong with it?
Nominal dimension, average, tolerance? Data is interesting, but likely should not be taken as "gospel".The number of rifles I traded away without testing to my current standards is huge.
The makers of the ammunition you suggest is Lapua and RWS (Norma).
Dennis suggested Lilja and he chambered my 40XB with an Eley Match Chamber.
The choices as to chambers may not find the right chamber in a drop in.
The chart may leave you with more questions than answers.
While Eley is listed, RWS and Lapua are not but a friends Eley Match chamber will not accept Lapua.
