apache Posted January 4, 2011 Report Share Posted January 4, 2011 Mine's zero'd @ 35 yards, same POI @ 100y - just point and shoot. Zero closer then try shooting further. Quote Link to comment Share on other sites More sharing options...
kyska Posted January 4, 2011 Report Share Posted January 4, 2011 (edited) I think you might also do better with a higher mag scope with a finer reticle, x4 will have a lot of variance at 100 yards. I had a real problem with zero with mine with a x7 meopta on it, the spot in the middle was bigger than 1 inch at 100 yards, making near impossible for me to get a good zero. Someone off here (in fact I think it was you, al4x)advised to try a higher mag, went to a x12 and never looked back.

silpig5 Posted January 4, 2011 Author Report Share Posted January 4, 2011 when shop set up scopes they said they used laser sight on wall ? i will try the shorter range idear , i realy dont know if its me or a scope prob , i was liucky with 22 it only took 30-50 shots for a bang on 60yd hit . perseverance is the key i think , and more bullets !!

Paddy Galore! Posted January 4, 2011 Report Share Posted January 4, 2011 Might need to bed in a bit, what's the cleaning regime like adi? Quote Link to comment Share on other sites More sharing options...
kent Posted January 4, 2011 Report Share Posted January 4, 2011 New HMR's often need a lot of cleaning initially. Personally i like to shoot one clean, shoot one clean for the first twenty shots then shoot three shot groups and clean till you have done 50. Shot 50 from a new bore without a clean then its going to want doing. Don't use 100 yds zero initially its a very windy calibre at 100 yds and you need the right day and 100% confidence you are on the button windage wise. Start initial zero very short range say about 20 yds to get a refined initial windage zero dont bother much about elivation just get it within an inch or so. Now the important bit take it to 40- 50 yds and run the elivation up and down to max and minimum, the impact points of the high and low setting group should be vertically aligned. This proves you scope is correctly aligned to the bore. In a 10 mph wind blowing directly from the side you bullets will drift around 4" at the 100yds pushed by the wind!. 5mph aint much wind but it will still go 2" off target, unfortunatly it won't be steady and constant and this alone could acount for your 3" groups. Personally i like to put the HMR on paper when the wind is very light and blowing directly at me or directly away, no wind just generally means you cannot call the speed or direction. To shoot consistant sub MOA (1"approx) 100yds groups with the HMR you realy do need the right conditions prevailing. With true nil value winds it can be an impresive calibre, just dont expect it as a matter of course Quote Link to comment Share on other sites More sharing options...
bunny_blaster Posted January 4, 2011 Report Share Posted January 4, 2011 Run a bore snake through it mate. My groups open up after 25-30 shots. After the snake has gone through its back to normal. Cheers Ben Quote Link to comment Share on other sites More sharing options...

Redgum Posted January 4, 2011 Report Share Posted January 4, 2011 (edited) The first thing is not to let it rattle you,most of us have been there and its bleeping frustrating especially with the cost of ammo. I'm guessing you are more used to a .22LR,now you are shooting further it will take more practice and the little hmr round will float about on the wind so pick a still day. You really need a higher mag scope, check that the barrel is free floating if its meant to be free floating. You will need to keep the gun still for zeroing,best in prone position or off the bonnet of your truck with some sand bags or a fixed bipod. To shoot sub 1 inch groups takes some skill regardless of how acurate your rifle is,don't believe all you hear on this forum for a start. Though the little round has virtually no felt recoil the louder report compared to a .22lr with subs or an air rifle can make you flinch. Settle yourself down and concentrate, if it were that easy we would all be shooting in the coming Olympics. I expected my CZ varmint hmr to shooting same hole groups out of the box but I tell ya, its been a love/Hate relashionship but after two years I wouldnt be without it now, cracking little gun for bunnies.

I think it was kent who advised to bed the thing in and clean often, this works well for mine too. Quote Link to comment Share on other sites More sharing options...

yankeedoodlepigeon Posted January 4, 2011 Report Share Posted January 4, 2011 Is all you do to clean a HMR run a bore snake through it? how often will it need tetra gun cleaner put through it? or will copper brushes be as good as the snake? some say run clean some say run dirty. on average say every 50 rounds bore snake or copper brush every 1000 gun cleaner?

Raja Clavata Posted January 4, 2011 Report Share Posted January 4, 2011 Are you shooting off a bipod or bags or what? For zeroing / grouping you want to take as many variables out as possible so make sure you are comfortable and the gun is stable. As suggested see what kind of groups you get at 30 yards. As also mentioned you need more magnification with the scope. I hope the shop did not recommend 4 x 50. Shooting off bags from a comfortable position with something like a 8 x 50/56 scope you really want to be grouping within a 2cm diameter circle.

silpig5 Posted January 13, 2011 Author Report Share Posted January 13, 2011 update on zero got a new scope night eye 6-20x50 and started from scratch at 30ish yards after 10 shots bang on outer bull consitantly . needs some fine tuning but work had to be done . and just to recap both times i was sat on a barrell of oil in the back of van gun resting on bean bag on a plank across both work benches .van is a mobile workshop . . thanks for all the pointers getting it right ! cheers adi Quote Link to comment Share on other sites More sharing options...

Mine only really settled down after several hundred rounds and got progressively better as time went on - This could easily have been me getting used to the rifle and gaining confidence in it though! When I am zeroing I tend to start at about 35-40 yards and then move on out to 100 which is what I like to keep my 17HMR zeroed in at. I use a set of 4-16X50s on mine but only use the max settings for checking the shot placement, while actually zeroing and shooting I tend to keep it down around 12X magnification. With that, even at 100 yards (Assuming that all is well with the scopes etc) you should be looking at around a 2 inch group max at 100 yards. Co-incidentally i was out zeroing my hummer today as I had the rifle and scopes stripped down for a good cleaning, here is the target I ended up with. The Red "Bulls Eye" is exactly 20mm in diameter - I have now "fine tuned it by giving it 1 click right and 1 click up (1 click = 1/4 inch @ 100 yards). (The flyer which went about 1 inch high was bad shooting on my part and not the fault of the rifle or scopes) Edit: I should add that this was shooting off the bipod on the bonnet of my 4X4!

silpig5 Posted January 14, 2011 Author Report Share Posted January 14, 2011 approx 150 before i got it , they cleaned it before sale , ive done 75 im very happy with the new scope as im getting overlapping groupings at 35 yards and similar at 100 .although ive not mastered the dead still hold even when leaning on a bean bag . the outer bulls i mentioned are in a 1"circle . i havnt had the time to fine tune yet but weather pemitting im out again tomorrow . how often do you sugest a pull threw or full brush clean on a hmr ~? cheers adi Quote Link to comment Share on other sites More sharing options...
Frenchieboy Posted January 15, 2011 Report Share Posted January 15, 2011 It sounds like your rifle is still in the "bedding in" period to me, if it's anything like mine you will find that the accuracy improves with time! At least now that you have fitted better scopes you are getting somewhere, which is good news. As for cleaning, I am a bit of a "fiddler" according to my wife who says I spend far too much time tinkering with my guns (It's better than watching Corrie or Emmerdale any day). As for cleaning the barrel of my 17HMR I find that it can be a bit of a messy round catching most of the crud in the moderator so I just run a mop with a small drop of oil through the barrel every 100 shots or so and then strip and clean the mod at the same time - It seems that the mod (Mine is a SAK) seems to gather most of the crud and starts to get quite messy after 100 or so rounds but treating it this way does help to make it last. Once I have stripped and cleaned the mod and run the lightly oiled mop through the barrel all I do is fire 2 or 3 shots through it to check the accuracy which is usually fine.

mosa Posted January 16, 2011 Report Share Posted January 16, 2011 Ive had a few and the last Cz i had was zerod in within 10-15 shots I do a quick bore sight in the garden then start at 30 yrds then 85 yrds (thats usually good to 150 yrd)couple of checks at 100 and spot on. I find them pretty good straight out the box. I always use a bipod and i must admit i never cleaned mine much ( i allowed barrel to cool between zeroing sessions) Quote Link to comment Share on other sites More sharing options...
