clean your 17hmr like a centre fire.

My hmr started to lose accuracy. But I didn't realise I was
supposed to clean it like a centre fire, copper solvent up
barrel for 15 mins and then give it a good scrub and then
patches until clean etc.
It was wrotten.
2000+ rounds through it and never cleaned
After the cleaning and 20 shots later it was back on target
hitting penny's all day long at 100yards

How many rounds did it take for your hmr to settle down again
after cleaning? One of mine was bang on on first shot, another
took a box or two, and the current one hasn't been fully cleaned
yet, tho it only had about 400 rounds from new

Always a lot of different views when it comes to cleaning the
HMR - some rarely clean, others clean every time they use it.
The method of cleaning is also a subject of debate. Some folk
use rods and wire brushes, others will only use jags with the
rods - there are also those that won't use rods at all and
insist on various 'pull throughs' like bore snakes and
patchworms etc. I use a patchworm pull through - with a cleaner
that will remove all the crud and any copper fouling - don't
know if it is as good as a rod etc, but I find it works well and
is relatively easy to use. Rods can be a tight fit for a small
bore line the .17 and require careful use during insertion -
some will only use them with the recommended bore guide. Multi
piece rods are not recommended as the joints can score the
rifling inside the barrel - a decent single piece rod is best if
you are determined to go down this road. The choice as to
whether to clean or not to clean, and indeed, how to clean, is
not always an easy one.

Almost all pro shooters wil only use a solid ome piece rods
And the usual method is patch soaked in copper solvent up barrel
And left for at least 10 to 15mins followed by a good scrub with
a bronze brush
About 10 to 15 full length run never stop half way always go
right out and then back
In until out the other end this is better for your rifling and
ur bronze brush.
Follow this by endless amout of patches until they come out
clean.
Finish with a patch with a small amount of oil on it to protect
ur barrel.
As for pull throughs than aint worth the cash as they dont
actually clean properly I've tried it and after 10 pull throughs
and then cleaning with a rod an copper solvent it was still
extremely dirty.
The pull through can't possible clean the barrel when your
continually pull the dirt back through the barrel!!!!!

Some will agree, some won't. If you look at sites like
Rimefirecentral and .17HMR.net this topic is hotly debated.
Cleaners/solvents have come a long way and are very effective.
A new cleaning pad is used with the Patchworm each time it is
pulled through and is seems to do a good enough job. I presoak
with copper solvent and after waiting about 10 minutes I start
to pull the cleaning pads through - works pretty well. The
actual amount of copper fouling associated with the HMR round is
yet another topic of debate - some say it is significant, others
take the view there is very little - I use the solvent anyway as
it won't do any harm. If I was to pass a rod and jag down the
barrel after using the Patchworm would a patch come out
completely clean? - maybe/maybe not, but does a barrel have to
be perfectly clean? - guys on the aforementioned [and other]
forums have been shooting HMR's for years having never used
cleaning rods with their HMR's without any ill effects - some
have gone to the bother of having the inside of the barrel
inspected to check for any damage etc and have found nothing.
Some will tell you that you are more likely to make a 'cock up'
when cleaning with a rod as opposed to a pull through like the
Patchworm. As with all things if it is done properly there
shouldn't be a problem. I wouldn't prescribe any particular
method - people can do their own research and seek advice and
then decide for themselves.

I have never heard of a pull through u can put patches on until
now.
The only thing I personally don't like with the pull throughs is
it's very had to give it a good scrub.
As for being as clean as possible, you dont want a rifle to sit
about slightly dirty in the uk humidity as metal here
deteriorates rather fast compared to ghe us and other countries.
If your wanting to achieve greater accuracy aswell you should
have the internals of barrel as clean as the shot before and not
to let much dirt gather up.
I know I sound like a clean freak but im truly not.
I wilp only clean like it going out of fashion when testing new
rounds

A lot of people don't clean their .22lr rifles....ever - the
barrels on their rifles will last longer than you or I. Once
you fire the first round of any rifle the barrel is going to be
dirty and continue dirty until you clean it [by whichever
method] you are not going to get the barrel as clean as the
previous shot unless you clean after each shot - in fact many
rifles shoot better dirty and require a few rounds to get back
'on song'. The HMR is a more dirty round than the .22lr and I
like to clean mine after use...I just use a different method
than you. If you google .17 Patchworm or look for it on ebay
you will see what is a very simple and easy way to clean the
.17. Those that prefer to use a rod can still use the Patchworm
between rodding if they wish. I would however advise against
scrubbing with a bronze/brass brush - the rifling on the HMR
[though harder than either bronze or brass] might be affected by
heavy scrubbing of this kind over an extended period, especially
with an agressive back and forth type action. Every man to his
own as they say.

Disagree alot with a bronze brush damaging the barrel.
If a projectile covered in copper going up the barrel at 3000fps
wont damage it never in 10 billion bronze brushes will it do any
damage or ware.
A .22lr or a air rifle is much different because of what the
bullet/pellet is made of and the speed it travels at compared to
copper jacketed ammo.
Usually rule of thumb for air rifles is clean after 500 but as
the is no chemicals involved there no need to unless accuracy
starts to slip. I did not clean my hw100 for 2 years until
accuracy started to go a good clean and a few hundred pellets
later it was hitting sub inch groups at 60yards.
Yes I agree the barrel will get dirtyer with ever shot fire but
accuracy may go off,you may not notice it at .22lr ranges.
Consistency is the key here you want to replicate the same
procedure over over you can not do this if the barrel is getting
more and more dirt in it and the bullets are gradually getting
slow because of the dirt gathering.
now this is being really anal now but at the end of the day the
more accurate I am the better I fell taking the longer shots on
foxes at 200yards+
1000yard bench shooters clean after 10 shots depending on what
there barrels like there are a few video's of bench rest
shooters talking about cleaning and every gun they have likes to
be cleaned differently some after 10 shots some after50 shots.
But this is boys that are getting sub inch grouos at 500yards
for the fun of it.

I don't have the time (or inclination) to clean like the bench
rest boys do, as long as its accurate enough for fox or rabbit
etc I'm happy. Pull throughs/bore snakes are useful as a couple
of quick pull throughs cleans it a bit but you don't tend to
lose the accuracy like with a full clean with brushes. Its only
a stop gap though, I still give a full strip and clean with
brushes at least twice a year anyway, quite often I use a 3 or 4
part rod but the key is to insert the rod from the muzzle and
the screw on the brush, jag, etc when the end of the rod is
sticking out the back of the receiver, then pull the brush
through it like a pull through. Alot of the damage from rods
cones with it flexing in the barrel as you push it through, is
this prevents that (though be careful with the crown). Saves the
need for a bore guide as well

Very interesting, I have a new 17mhr cz silhouette, and find the
17 a very dirty round.
After every shoot I gun lube a hoppes boresnake, which has brass
brisstles and draw a few times in the direction of fire.
If I don't do this, I loose my zero after 10 - 15 shots.
If I leave any oil in barrel also need a few clearance shots.
Complete strip, clean, lube maybe 6 -12mths.
Always been told a cpc aririfle barrel should never need
cleaned.
What u say?
