Bore Cleaning Frequency

Postby jaysny87 » Wed Mar 18, 2015 8:31 pm

There doesn't seem to be much common ground when it comes to the question "how often should one clean his long range rifle".

This is a pretty good read.

So using hand loads and not any surplus stuff how often do you guys clean your long range Mosins?

Most barrels shoot best when slightly fouled. With most of my barrels I see that it takes about 5-7 shots to get it to settle into a group after a thorough cleaning. Therefore I don't clean my bore until it gets so dirty that accuracy starts to fall off. Then I clean it and shoot it to settle it into a group again and it stays that way until accuracy starts to fall off again.

Now the most important part of my system is using a bore snake to remove the heavy deposits. When ever I finish shooting I pull a bore snake 5 or 6 times to remove any large powder or other deposits from the barrel before putting the gun away. This greatly reduces the chance of any rust or corrosion developing in the barrel while it is stored. But more importantly I have found that this GREATLY increases my percentages of first round hits on long range targets. All of my guns are hunting guns first and fun guns second. If I let my guns sit without snaking it any deposits from the last shooting seem to harden and raise the bore pressure, making the first shot out of the bore go high and right. This is very minor at 100 yards but at 500 can shoot clear over the back of an animal. (I've done that). So anyways I've found that if I snake it and put it away, 9 out of 10 times I can grab it, go hunting, and put a first round, cold bore hit in the kill zone out to about 750 yards.

The boresnakes work well for that but another method I will use is to run about 10 strokes with a NYLON brush. Then run about 3 dry patches through it. Again I do this immediately after I finish shooting while any deposits are fresh and warm. Both of these cleaning methods seem to be very effective at keeping the "bullet fairy" as my buddy calls it, from stealing the cold bore hits.

In my opinion cleaning your bore before a degrade in accuracy is like wiping before you poop. ;)

:lol: I like that. That's a good way to put it.

I try not to mess with the barrel unless I have to , but I do use a shot-gun brush in a drill on the chamber after every session , followed up with a mop with Cleaner on the mop . Then dry patches to remove any excess . Do this barrel tipped slightly up , to keep cleaner out of it . I also clean the bolt face , extractor , and add a drop of 3in1 down the firing pin hole.
Seems to be more consistent in "charging" the round into the chamber & locking the bolt. Solid ... At least it feels that way to me
If not me.....Who ?
If not now ....When ?
