Cutting 452 american barrel down?
 
Anyone ever considered doing it to say 18" or 16" I've often thought about doing it for better accuracy and maneuverability but am still a bit chicken about going through with it. Mine shoots really well .5"-1" at 50yds without really trying..Wondering if it would shoot better at a shorter carbine length.

Why do that? If you want a short CZ just buy a scout.that way you would have 2 good shooters and a 455 platform Incase you had any more what If thoughts !:D

Hunter2678 11-08-2018 10:40 AM

Well....so I wouldn't have to buy another rifle to do it!!...I guess for sh*ts and giggs I could expand my original question to include 455s as well.

A friend of mine recently purchased a 455 stainless, a super accurate rifle right out of the box, he had the barrel threaded for a can, I feared he might lose accuracy, instead it became THE rifle to beat, it simply shoots lights out.
He didn't cut it back, just had it threaded but it was already near 4" shorter than the 452s

Three things:

a) it's your rifle, do what you want with it.
b) personally, I don't mess with rifles that shoot well.
c) I did this with a Savage BTVS that had a tight spot in the barrel about three inches before the muzzle. Took about three hours and it and it did improve things.

Here's how I did it:

If it shoots that well it is a shame to experiment with it. Many folks here would readily swap you a 455 for a 452. Then you could experiment with cutting the barrel and easily replace it for little money if it doesn't work out.

Yeah I have a couple of other 22s with 16" tubes and they shoot great..they seem more consistent than my 452.

Whack a 452.........now that's just..................! Look at the prices a very clean 452 will bring today!

Why would you cut up a subMOA rifle that is worth at least its purchase price? Looking for them halfMOA groups, are ya? Well, good luck with that. "Try..." and shoot better, use some better ammo, but don't take no hacksaw/Sawsall to it.

Not looking for one hole..Im looking to keep or slightly improve the accuracy without the extra barrel length...I love a 22 carbine for a carry / hunting rifle. Thats my rub with the 452. Barrel is about 4"-5" too long for my preference. Its just un-needed length IMO.

At the end of the day it’s your 452. Can you cut the barrel, of course. Will it improve accuracy, likely not any more than finding the best ammo for your rifle as is.

Folks around here are likely not going to be fans of significantly and irreparably altering a 452 that shoots very well as is. Frankly, they are hard to come by and there are probably several who would buy that 452 from you today. Then you could buy a rifle that fits your desired barrel length.

But again, it’s your 452.

In spite of what some think there is nothing super special about a 452. It is a mid priced production run sporter, if you want a 16 inch American, make it so. You paid for it, alter it to a point where it makes you happy. Will it be more accurate, maybe, if done properly there should be no loss in accuracy.

Hunter2678, not trying to admonish you, it's your rifle, to me it would be sacrilegious, but that's just me. I still do feel a clean 452 is just to valuable to cut considering it's no longer in series production, better to sell and replace with 455 and be able to easily replace a barrel that "could" be ruined. Happy Shootin'

Get a Youth, OR, perhaps consider a Ruger American, with 18" - sure handle well in the woods ;)

FWIW, I like 17-20" for field use....good luck whatever you do.

Toomany22s 11-08-2018 02:50 PM

You all are being too nice.

When you cut it ,save the cut off ,you can weld it back on again.

You asked, we told you it’s a crummy idea, you’ll be sorry, you can buy another gun for the same amount of money it’s going to cost you to do this. This is not a first timer diy project.

How is this 4 inches getting in your way? unless you are extraordinarily short or tall pointed down is pointed down or up is up which is where the muzzle should be if your moving.Are you dragging in inthe dirt, poking the ceiling?

Ps you do know there is a choke point in these barrels, like the anschutz and that’s why they are extremely accurate.its usually 2 inches back from the muzzel. Don’t cut off the choke point! You will be sorry!

And if you cut it off your hair will never grow back:D

Did you know that short barrels cause you to go cross eyed?

Additionally, CZ Protective Services will separate you and your rifle and there will be other fines and penalties involved.

There are a million reasons not to do this. And only one to do it. Your impulse. Has that ever worked out for you?

Hunter2678 11-08-2018 02:57 PM

my friend is a gunsmith its getting done professionally........if I decide to go through with it..gonna follow my mom's advice when I was a kid & sleep on it for now. lemme tell ya..that extra 4 inches hangs up in the woods like a CB antenna on a car goin through a carwash...Im short legged and long torsoed. **** near Dorf like!

Yuuuuck!!:eek:

I tend to think that the question you pose conceals a wonderful opportunity. Rather than a barrel reduction of the rifle that you own, consider converting a few greenbacks into a new asset - in the form of a 452 or 455 Scout.

That way your American will have a fine companion and you can play them off one against the other - for best accuracy and best handling in the field.

My 452 Scout is a bit more accurate than my 452 Lux, and I have yet to wring out my new-to-me 452 trainer. But I assure you, that in my case, the feeling of accomplishment is fuller in acquiring a rifle rather than in irrevocably altering one, when it is already very accurate.

Good luck,

Dyson

If you were to find yourself in a position where you needed crutches and they were 4 inches too long would you leave them as is? My bet would be that you'd cut them to your needs!

Al the Infidel 11-08-2018 03:33 PM

I say cut it if thats what you want. The naysayers been around since circumcision became popular. :D Since you have a good smith have him slug it first would be my 2¢.

:yeahthat: If the bore is tapered properly, you can cut and crown to any length and enjoy the same accuracy potential. This job calls for slugging the barrel, if a smooth, even, slightly tightening taper from breech to muzzle is found, go ahead and cut to desired length. If some variation in bore diameter is found, cut the muzzle where the bore tightens up near the length you want, but dont get hung up on "the barrel must be exactly 16.000"", it'll have to be what it needs to be, 16.43", 15.75", wherever gets the muzzle being the tightest spot in the barrel. If you have a tight spot just behind the crown and it opens up to the muzzle, you could have problems.

Someone said something about CZs and Anschütz barrels having a "choke" at the muzzle that you shouldn't cut off... fake news. Production facilities do not put that effort into their barrels, and while I don't doubt that some examples anecdotally have a choke in them, the existence of such is coincidental, not by design. I've slugged three Annie barrels and they were all different. One was the ideal gradually tightening taper, no choke. One was like a speed bump tight-loose-tight-loose-tight to loosening up out the crown, dud barrel. The other did apparently have a choke, a 64 MSR barrel that has a swell in diameter at the muzzle. Theory is removing metal on the barrel profile behind the swell allows the bore to expand while the untouched portion remains tight, creating the choke. Intentional? Maybe not, as the swell is dovetailed to accept a globe sight and align it with the rear peep. Point is, you are going to find considerable variations in the bore diameter consistency in factory made, non hand lapped barrels. Slug your barrel and base your decision on those results.

CZ used to make a 16" threaded 452 american. we had one, it was good for 1 MOA. my 452 varmint, my buddies 452 varmint and my 22" 452 american have all shot well under 1/2 MOA. so a shorter barrel doesnt mean it will shoot more accurately, and with the hammer forged barrels when you thread them it does induce some choke. i also have 2 anschutz match rifles that are very long barrels and they are very good shooters. 1 better than everything i own, typically 1/4 MOA. the other shoots with my sub 1/2 MOA CZs and 10/22s. if it were mine and shoots good, i would leave it alone and buy something else if you want shorter.

ODEN2 11-08-2018 08:42 PM

452 16" Threaded
 
I got one and YOU CAN'T HAVE IT! It's my favorite rifle bar none. With a suppressor its deathly quiet and amazingly accurate, not quite up to my 452 thumbhole varmint at 100 yds but almost.

Sorry to hijack the thread, but I just felt like bragging.:D

As for the OPs problem, I'd buy a Scout and an American stock, small riflle in a full size stock, but that's just me and I always make the wrong choice.:o
