Thread: cleaning the HMR

So chaps, what are you doing to clean the HMR barrel?
Do you use copper remover, with a jag? Or some other method?
I have a 17 cal rod, jag and bronze brush but can't find patches thin enough to go in the barrel. I tried paper type ones but they come off and stick in the barrel.

I've tried using cloth ones but you've gotta cut em pretty small......

I found the smallest square ones then cut them down till they fit, tedious would be a plesent term to use.

Get a Boresnake, they make them in .17 and it works fine for me.

Otis cleaning gear, small patches are perfect for it.
When I stock up I buy from Otis direct and youshop it over.

Otis Technology

I got me one of those all calibre kits they sell and just took out a few things and topped it up with oil and patches

FYI these are pull through cables, means you don't have rods to luge around and they are very sturdy

I use bronze brush and jag with patches, I use copper remover as well, the small patches at H&F are marked .17 and work ok. I don't clean every time, still maintains accuracy, Happy advised to remove the suppressor be fore storing due to condensation so I do it!

Soak both ends of a Johnson's cotton ear bud in boretec copper cutter and pull it through the bore with heavy fishing nylon, repeat 20 mins apart until no more blue colour-copper is observed.

Finish with a dry cotton bud.

Perfect results every time

Are hmr in need if more cleaning than other calibers? I haven't cleaned mine yet and is still cutting satan birds in half at a 100

I only just brought an HMR two weeks ago and got round to firing it in the weekend. Couple of guys hinted that they are a mongrel to clean.
I just used a one piece rod, bush and copper remover , dry patch's then a lightly oiled patch, no problem at all, same as any other rifle to clean.

Cotton bud cut in half on the end of a cleaning rod works a lot better than the tiny patches

Have a chat with some small bore shooters. You'd be surprised by how many guys are getting higher scores with clean barrels.

Plus they (HMR) are firing jacketed projectiles, not lubed lead. Probably need the same care and attention as a normal Centrefire but then many don't bother to clean those

I just use a bore snake, seems to work well.
No idea how often I need to clean mine, usually just when ever I feel like it.
