Nickt Posted August 18, 2014 Report Share Posted August 18, 2014 I went on the range yesterday to zero my 223 CZ 527. At 50 yards it grouped just over an inch, but out at hundred yards the groups opened up to around 4 inches. Is this normal, can just be the bullets or something else might causing it (could even be me)? I used PPU 55gr bullets. The scope is a cheap nikko sterling gamekeeper properly tight. The range was indoors so no wind issues. I have put around 25 rounds (all PPU) through the rifle since i thoroughly cleaned the barrel, but the barrel still seems to be very clean. Someone at the range suggested it might need more rounds to get back to grouping properly. I will try to go back and try different bullets, and also have some shots without the mod. I welcome any advice. Quote Link to comment Share on other sites More sharing options...
Archie-fox Posted August 18, 2014 Report Share Posted August 18, 2014 Could be the ammo mate... Had to try 4 different types of ammo to find the one my 243 liked.. Quote Link to comment Share on other sites More sharing options...
The Essex Hunter Posted August 18, 2014 Report Share Posted August 18, 2014 I checked mine yesterday in that strong wing as you must know what happens with a bullet as you cant always pick a still day/night... The 95's @ 150 were 3/4 inch group of the sticks, however the 75's went left in a strong right hand cross wind.... I tried a couple of rounds of a different make I brought on a whim....well they went 3 inches low and 3 right, so a waste of £24.00!! I zero in field conditions as there are not many foxes/deer on the range... TEH Quote Link to comment Share on other sites More sharing options...
Bewsher500 Posted August 18, 2014 Report Share Posted August 18, 2014 my .222 didn't like PRIVI 55gr we need more info to make any judgement or offer advice 1) is this the first time you have shot it, did it shoot better before with other ammo by someone else etc etc? Need prior data 2) anything changed since the above if this is the first time you have shot it check everything! tight screws/mounts/action screws barrel/stock free floating clearance if designed that way swap and check with a known good scope if possible if its a placcy stock ditch the bipod and shoot off a bag try some other factory ammo report back Quote Link to comment Share on other sites More sharing options...
Scully Posted August 18, 2014 Report Share Posted August 18, 2014 Try different brands of ammo as suggested. Setting up on an indoor range with no wind to contend with sounds ideal to me. Quote Link to comment Share on other sites More sharing options...
Nickt Posted August 18, 2014 Author Report Share Posted August 18, 2014 Thanks guys. I will try diferrent ammo and let you know the score. Quote Link to comment Share on other sites More sharing options...
Peskyfoxs Posted August 18, 2014 Report Share Posted August 18, 2014 Which range did you go to ? If it was Stead hall John will sometimes have a few part boxes of ammo you can buy to try. Quote Link to comment Share on other sites More sharing options...
Dekers Posted August 18, 2014 Report Share Posted August 18, 2014 Is this your first experience with this ammo or have you used it before, what results did you get historically if you have used it before? Did you THOROUGHLY clean it, I make no suggestion here, but it is not uncommon for people to suggest they thoroughly clean when they give it a quick once over and simply raise fouling, this is what commonly leads people to say you need 10-20-30-40-50 or more shots after a clean to get it back. 4" groups do not really give you a great deal of encouragement or confidence in any gun/ammo! There could be many answers/reasons for this issue, perhaps a more detailed background may help. PRVI works for some people and not others, fortunately it works for me, I use PRVI as a mainstay for field work and the .223, .243, .308 PRVI SP all deliver 1" in my rifles, that is plenty good enough for general field work!

Try some Hornady, Fedral etc and see how you go then Quote Link to comment Share on other sites More sharing options...
Nickt Posted August 21, 2014 Author Report Share Posted August 21, 2014 Right i went back on the range yesterday to try a couple of different rounds. I left the rifle as it was the last time around with no twicks. I first fired 3 shots of Hornady's. They went 4" hight with 1.5" grouping. Then i had 3 shots of federals. Bulls eye with 3/4 of an inch grouping!!! So it looks like the rifle just doesn't like PPU's. Very happy now and federals all the way Quote Link to comment Share on other sites More sharing options...

Kes Posted August 22, 2014 Report Share Posted August 22, 2014 (edited) Worth trying to reload a bit and get your best load. Mine doesnt like PPU either much - Remington 700 but they are ok if pushed - 2"group or slightly bigger, at 100 yds. Federal are not good and the cases arent good for reloading - primer pocket problems. Hornady 40 and 50 grain v max are great - 1" or less difference at 100 yds My 'advised' home load recipe produces 3/4" group at 100yds and 55 gr Hornady v max, pushed by 26.0 grains of Accurate, in my friends rifle produced a 1/2" group at 100 yds - Tunnel range, useful for checking before starting out on the foxes and a bit of fun. Keep looking as you may well find better, until fully happy. Try the odd 40 grain - very flat and instant dispatch.

kent Posted August 22, 2014 Report Share Posted August 22, 2014 I have used Federal cases quite a bit and never had a quality issue with primer pockets or anything else once all prep done I found them very long lived actually even in the .243. What problems occurred with the pockets in yours or is it net hearsay? Quote Link to comment Share on other sites More sharing options...
iain Posted August 22, 2014 Report Share Posted August 22, 2014 +1 for reloading. I've got a ruger m77 mk2. I've had to reload for as it don't seem to like factory ammo. Quote Link to comment Share on other sites More sharing options...

What problems occurred with the pockets in yours or is it net hearsay? Kent - why do you have this certain cynicism, 'net heresay'. No I actually bought about 100 federal 55 grain to try and after trying them - not the best and quite variable, I tried reloading the cases. When cleaning out the primer pocket with the tool (reamer) the tool I have could not be rotated in the pocket by hand (it works for all my other cases) - I have a firm grip so they are undersized, all too often. Tried and succeeded with a few and the first three which appeared to be of the right diameter, the primer would not seat smoothly or stood proud rather than the nice 0.5 mm depression after seating - obviously unuseable. So whilst you are prepared to suggest others have no experience and its just 'net heresay' - how come you havent found this when a good number of others have and mentioned it in previous posts ? You can occasionally be rather irritating - stop it, as it spoils my view of your other posts. Quote Link to comment Share on other sites More sharing options...

You can occasionally be rather irritating - stop it, as it spoils my view of your other posts. Don't take offence so easily it was just a straight question about your issue. No more meant than that, if you had said a batch I had had tight pockets then fair enough ( I wouldn't find this ever as I always uniform the pockets). There is a lot of net hearsay about these days and its hard to wade through at times hence the question, I should rather have a tight pocket than a slack one for sure but obviously we can have conspiring tolerances of primer and pocket to consider. If you said split necks etc then I might think twice about the brand Federal brass I personally rate about equal with Winchester behind Norma, RWS. Lapua but significantly above the others Quote Link to comment Share on other sites More sharing options...
