Its ok to take a grinder to a new gun, right?

[W. Honeysuckle]

Geeze, so the cz452 I just picked up apparently has quite a high sitting bolt... After getting some high leupold mounts it still was scraping its nikon 3-9x40 scope!

Well, I have not shot it yet, but I just had to take the grinder out to make it work....maybe there's other options, but here's what happened:

And, next to the hunting rifle...300wsm tikka.

I really wanted this gun as a good practice rifle for hunting. I figure if I can match as closely as possible the same rifle I practice with to the one I hunt with, I will spend fewer shots with more hit game. So, any mods I will do will try to make these feel the same. I'm thinking maybe of playing with the bolt knob on the cz, its pretty small. And, possibly getting the trigger down to the same poundage and creep. Both scopes are same mag. with ballistic reticles.

Umm... You should be "practicing" with the same rifle you will be hunting with.

Your gun=your call, but I would never take a grinder to any gun, let alone a CZ. I would have started with higher rings and/or a smaller scope. Any scope will be a tight fit with these guns, but no grinder should be necessary.

I would have mounted a scope with a smaller diameter eyepiece housing, such as Leupold. But that's just me.

The bolt on my 452 would not pass the power ring on a Bushnell 3000 3 - 9 power. I took the grinder to the scope ring between the 3 and 4 power marks. That does not show when on 9 power but once off 9 power the bolt did not function. A Leupold Rifleman 4 - 12 allows the bolt to function, and Korth adjusted the parallax to 75 yards.
CCI MiniMags HP at 50 yards - 5 shots in .2 (C-C). The rings used were the Leupold 13 mm ring mounts.

dude, its your gun, you can modify it anyway it fits you....just because thats what it came from factory doesnt make it set in stone.

Is it a collectors item? Is it uber rare? whats the point of a gun that you cant a. use or b. have to go and get another $500 scope for?

I just modified my Marlin XL7 in 223 to accept magazines instead of a blind magazine. oooh blasphemy!

 

[kamlooky]

I ran into the same problem. New Legend with the ocular lens too big/fat around.
Found a scope that would fit.
Grind away, it's your rifle.
Worst that can happen is you lighten the gal up a bit.
If the bolt knob falls off, ye'all went a tad too far.............

be careful when you grind that scope.

 

[kamlooky]

be careful when you grind that scope.

Or grinding the bolt.
The sparks will pit the glass.
Not very nice................
Cover the scope up very well.

Only ever modify (i.e. grind) the cheaper part(s); never modify the part with the S/N on it, and preferably only modify parts than CAN be easily replaced (some parts can't be bought easily - Ruger for example won't sell many small parts.)

If you follow the above, go nutz

Get the higher rings, Talley, Warne, Burris, BKL. And be done with it, the Leupold's aren't high enough. I have the BKL's with a Leupold 6 X18 VX IIIAO and it clears no problem.Rings are cheaper than a new bolt.

It's your rifle, do what you have to. In 1965 I took a torch to the bolt on a new sako.Every time I shot the rifle the recoil dam near broke my finger,its still has a off colour in the bolt but what the hell.

[gordfry]

I can't imagine modifying a new gun/scope combo. I would get something that fits. Different or higher rings??

 

[trebor2880]

Grind, Bubba, Grind!

 

[ricksplace]

I don't think I have ever owned a new gun that I completely left alone. Trigger mods, re-crowning, bedding, etc. usually gets done to every rifle. Your mod is functional and appears well done. My bet is that someone would have to be a cz connoisseur to notice the difference. Bravo.

 

[W. Honeysuckle]

I guess it isn't noticeable, but those pics are of the finished result...

I took maybe an 1/8" or less out of the point that touched the scope - I'm pretty happy with how it turned out, but the knob still feels short. I may have to look into extending it depending on how it feels after taking it out a few times.

p.s. I would never recommend grinding a bolt handle while attached to the bolt or let alone with the bolt on the gun, obviously, the bolt was taken apart and only the handle saw sparks.

Reason #637 to buy a Savage above all others...

Grind grind,,, grindy grind,,,, grindy grindy grind......I would never,,,, in a million years do that! LMFAO

Umm... You should be "practicing" with the same rifle you will be hunting with.

Umm... by all means you should be practicing with your hunting rifle. However much of my "practice" for hunting is done with a rifle I am not hunting with. Shooting skills are transferable between firearms that you are familiar with.

Say you have $300 to devote to ammo a year. You will be far futher ahead to buy 5000 .22lr rounds and 100 big games rounds and practice shooting all those from field positions than you will be buying 300 rounds alone for your big game rifle.

I used to sink all my ammo money into larger centerfire cartridges and shoot 500-700 rounds a year. Then I bought an AR-15 and started shooting service rifle. 2000 rounds of .223 can be shot a year for the price of 500 larger rounds. Plus 1000s of rimfire rounds from standing and kneeling on spinning targets on the the farm and you won't believe how much your shooting will improve with your big game rifles.

I don't see the big deal if it is well executed, as it appears to be in this case. I'll take modifying the bolt handle over a scope that requires a "chin weld" any day.
