Take your time Shootaway, many of us will still be around.

Obviously the CZ is defective, I'll give you $100 for it ...

It had a slightly loose front guard screw but it's still shooting good. I believe that the loose front screw caused the point of impact to shift upward several inches.I corrected the problem before I discovered the loose screw by using another leaf on my sights.Today I loaded W748 and 500gr Woodleigh FMJ bullets and shot from a rest.The first three shots are on the top left of the target.I then swithed to the 100yd leaf to lower the point of impact.I then fired one shot.This is the hole below and a bit to the left of the 3 shot group.I then unscrewed the sights and shifted them to the right and fired a 2 shot group.It would be a tighter 2 shot group if I had stopped to clean the bore.I was glad to see the rifle is still capable of a good group,especially with the 500gr Woodleigh FMJ bullets.I think it is very important to check point of impact on big bores from time to time.[URL= ]100yds[/URL]

Patterns like a blindman's shotgun, eh?

Must have forgot to flip up the tinted visor on his shooting helmet, and the sun went down in mid "group" or mid pattern.

looks like marbles in a slug gun barrel... like a 4 bore front stuffer!

here's some big bore groups that aren't as INTERESTING.. and no helmet


(George, this is YOUR barrel!)

My 470 AR


THREE shots... left hole is slightly larger

What about that "recoils like a 300 winmag" comment?

Cut the barrel off to 20" and see if it get better

You can never get it right,jeffeoso.I said that my Ruget bolt action Lott recoils like a 300WM.My CZ 458wm and CZ lott have violent muzzle lift.I got it on the nose and forehead more than once.Sometimes I think it broke my nose.I want to figure out why the Ruger is a pleasure to shoot compared to the CZ.

My CZ 550 in 458 Win has NO muzzle "lift" or jump, and I shoot it pretty hot! Although, it does have the BRITISH style stock and not the American or Euro...

Excessive muzzle flip on your CZ might have something to do with loads that are so overpressure that you are getting lose primer pockets after one loading. Or the possibility that your barrel is shot out after less than 200 rounds because you are using the wrong diameter bullets. Maybe.

Just some thoughts.

Didn't you tell us all that your CZ was keyholing becasue the barrel is shot out? Did it magically regrow rifling?

Is this with the same barrel that you shot out after 150 rounds due to using FMJs, or are you trying to wear out a new one?

Just the Lott I sent to the gunsmith.

The problem is noticed most,if not only when you shoot it offhand.Have you shot yours offhand?It does so also with the straight stock.I checked my crown on both Ruger and CZ and they are very similar except for the barrel diameter of the Ruger being greater.The shorter,thicker barrel, puts weight closer to the shooter.

I own a CZ 550 458 Lott and it doesn't jump up on me shooting it. But I let a friend shoot it and it jumped up on him. So I would guess it all the way it is held.

I took some video today and tried to put it here. I Hope I will figure it out and it will be posted here soon.I am starting to get the hang of it-shooting the 458WM with hot loads and shooting it offhand.I am getting ready for that good year that will allow me to go hunt a lion.Untill then,I should be happy with shooting at the range.The range is a nice place.When you get back from that special hunting trip and wished it would last forever,the shooting range makes it last forever.

I built a Ruger M77 MkII up several years ago, threw away the barrel and screwed on a absolute minimum contour E.R. Shaw barrel in .458 WM, than black-T'd the whole mess as a rifle for when I do my trips up to Kodiak Island. The rifle all together weighs 6.8 pounds, not to mention it has a 20" barrel. Offhand, resting, any style of shooting and the muzzle rise isn't "in the forehead and poking out eyes" severe.
Now I also have a couple of CZ's laying around in various calibers adequate for dangerous game, such as .375's, .458 WM's and Lotts and a 505 gibbs that I hate. Plus my brother owns one of those wonderful little Ruger Expresses in .458 Lott, and to tell you the truth they are about the same as far as muzzle rise. Stock design has a amazing amount of influence on muzzle rise.
As far as that little Ruger I built, I can shoot that rifle about as fast as other rifles in the same caliber, however I have noticed something. The gents who I have allowed to shoot it as sort of a right of passage, all allow the rifle to jump, and jump very high. From what you're saying than, you probably need more practice. If not, get out of the big bore scene and take a serious look at the medium bores.

The longish 25" barrel of the CZ 550 in 458 Win adds weight forward of the stock that SHOULD help keep the muzzle rising too dramatically. Nonetheless, stock shape and fit, as well as how the rifle is held, are major factors in controlling muzzle "jump" and sense of recoil.

I agree, practice is important, but a firm grip on the forearm and pistol grip while pulling the rifle into the shoulder, making the body a part of rifle weight, is equally important. A proper shooting stance is absolutely necessary in shooting offhand, and doubly so for big bores. The upper body should move with the recoil of a big bore while the legs are slightly flexed at the knees with the forward foot approximately 2.5 to 3 ft forward of the rear (depending of physical stature). The "front" foot should be pointed at about 1 o'clock and the rear at about 3 o'clock, if a right-handed shooter. If left handed, the forward foot should point at about 11 o'clock and the rear at 9 o'clock. The rear foot should be firmly planted in any case.

Yes, I've fired mine offhand and it's weight of about 10.5 lbs allows for a very steady hold.

You SERIOUSLY need to train on shooting...
Here's 2 videos of men shooting the 550 express, identical loads and the same rifle.

The one on the left is a fella that shoots ALOT of bigbore

On the right, a gentleman that hadn't shot anything bigger than the 45/70 is years.. and he's now hooked on big bores.

TRAINING is your issue... that you don't know how to hold a hogback rifle is kinda funny...

your youtube says you are 27 or 28? That explains ALOT as to why you are so pissy ... that much hair loss before you are 30 aint a good sign.. you are on high blood pressure meds, yet? that much hair loss before your 30s is a sure sign

I guess youtube thought that I was younger than I am.I can't see your videos.

wait for them ... no, really, click and wait for the page to download ...

There are two .550 vids here: shooting the .550

Thanks George.A couple of beginners? Someone shooting their cow?
