how long have you had the rifle? and if long do you use a copper removal agent on the hmr...........as you will need to due to the speed of the little round

give it a good clean then try again.....it may take a few rounds to settle down again..........but this is what i suspect to be the problem......

hi mate i have not had it that long got it last monday fired 400 rounds through it and pulled through the barrell after every outing

[SNAP SHOT 194]

did you shoot the barrel in properly...........plus 400 is a hell of alot in such a short space of time, get yourself some copper remover and give the barrel a good clean.........i'd nearly bet its copper build up.................good luck.........

[riggers 2]

hi mate what do you mean shoot the barrell in properly i know 400 is alot but we had a wee play on our ground we have a cracking little range and plenty of crows

[SportingShooter 0]

To shoot a barrel in means to remove all the imperfections in the barrel by shooting a few rounds, then cleaning it thoroughly, then repeating that so that the barrel is in "working" order. Its a bit late for that now. Seen as you have fired 400 rounds already.

 

But as Snap says, get some good copper solvent and scrub it out.

 

Then try again.

ok mate will do cheers all

right chaps barell scrubbed at what range do you zero at i have been zeroing at 100 yards but i only have a 8x42 scope and have to walk up after every 5 rounds to see where i am hitting was thinking about zeroing at 50 then giving it 1 click down for 100 any thoughts also what would be a good replacment for my nikko stirling 8x42 gold crown budget of say 100 maybe 150 if i get the old scope sold

Do yourself a favor and get a cleaning rod and all the necessary bits to go with it, their much better than using a boresnake.

Boresnakes...as has already been said IMHO...someone has done a brilliant marketing job for these and fooled a lot of people!!!

 

Nothing wrong with an 8x42 at 100 yards!!...I tend to use 6x for just about everything out to around 200 yards!!

 

Barrel scrub??? Is it shooting any better, did you use a copper solvent??!!

 

thinking about zeroing at 50 then giving it 1 click down for 100 any thoughts ...doesn't float my boat.....whatever you do you MUST check by live firing at 100 anyway!!!

I don't use a copper solvent, any suggestions on what to use. I have no bore snake, i use fishing gut doubled, and then put flannelet in the join to pull the barrel through. I have got rods, with wire nylon and soft attachments, so will use them from now on. I was going to buy a bore snake but dont think i will bother. I really appreciate all comment and advice thank you very much. :notworthy:

Many bore solvents concentrate on powder/lead removal with a bit of copper removal as well...copper solvent does what it says!!! I use Hoppe's but I suspect they are all pretty much the same!

 

HMR is a tiny bullet and quite fast up the barrel...and copper coated (the copper coat is generally applied to fast rounds to stop the lead bullet deforming with the heat of air friction and becoming inconsistant in delivery..as a bonus it assists penetration)....this being the case the bullets tends to leave copper deposits up the barrel and if the barrel has not been broken in effectively these deposits can often be laid down in the bore VERY inconsistantly and build up needing a proper copper clean!

 

This may well lead to the sort of innacuracy problems you have suggested.

 

Most barrels could do with a decent copper clean on a fairly regular basis although most general cleaners do an adequate job!

 

To maintain accuracy and optimum barrel life it is essential to maintain the bore condition to as high a standard as possible!

bore snakes are fine for a quick clean at the range or in the field...........but you do need to remove the copper in the hmr........So get yourself some.....

AND a decent rod kit, and all the necessary's or your wasting your money by shooting rounds that will be inconsistant upon firing.....

Cleaning the .17 regularly is in my experience essential to keep it shooting anywhere near right, every 75'ish is my benchmark.

Also get a proper dedicated cleaning rod AND a bore guide, Midway UK is a good website so is Rimfire Magic, but expect to pay Circa £40.00 for the Rod and Brushes, Also the brushes don't last long, the bristles are so short they bend over and stop working after a few uses, I buy 6 at a time. You can tell when you put a new one on as the force needed to push it down the bore is at least double that of a worn/knackered one.

I use Remington Bore Cleaner, I bought mine in the States (cheaper) but I've seen the stuff on the shelf in gun shops here as well, looks like Brasso and smells 'orrible.

Are you resting the rifle properly when zeroing? I use a harris swivel bipod, laid over a round hay bale, this is very steady and repeatable, I dont use the bipod when out shooting. Also you are using an airgun scope, and it's a big ask to get any precision at 100 yards, the reticule is just to thick and coarse, I'm afraid the only real answer is to get a decent i.e. (Expensive) scope, 4x Mag is fine, If you haven't looked through a high spec. scope before you will be amazed at the difference, a reasonable 'good' scope would be a 6x42 Hungarian Schmitd & Bender, these can be picked up second hand for about £250.

I have only used Remington Ammo, and I have had two misfires where the primer has fired but the main charge hasn't, pushing the bullet about 2" up the barrel, luckily I have the experience to know something wasn't right and stopped shooting, I don't know of anyone else having this happen? But look out for it. In both cases the pin strike on the Rim was deep and firm so it's not the rifle.

you can get a hmr cleaning kit for the hmr from rimfire magic. its only around £17
