Loss of accuracy after cleaning

[Richard Parsons]

Below is my 5 shot groups from my load development. Note they’re on 1cm graph paper, 5 shot groups for 32 and 39gr Sierra Blitzkings.

Good groups. Panic over I hope.....

Hi Nick, thanks for the tip; I’ve checked everything on the outside so something on the inside is a possibility. I’ll pop my Zeiss scope on, after I’ve done some groups altering other elements, to see if it is the Drone.
Cheers

Unfortunately not yet, those groups are historic from my original load development.

See why I rarely clean. To get it shooting again you have to make it dirty again haha

ok, removed rifle from action, cleaned action and REM installed, checked all external bolts on scope and mounts AND replaced the first baffle in my DPT moderator that I’d replaced due to gas cutting.
Shot the 3 shot group below off the bipod into a bank down by the river. It’s much better than it was and I’m probably happy with that under the conditions I was shooting in. I’ll give it another go tomorrow to see if I have also got first/cold barrel shot consistency.

So using a bore paste will not damage anything (if you use it carefully) but it will take a while for the rifle to settle afterwards.

I suggest including the above as it is quite possible to put a nice bevel on the last 2mm of barrel at the crown end if you use it frequently as can be the temptation.

They are not really aggressive. You won't hurt your bore using them. In fact they are oftentimes the render of last resort when all else fails cleaning wise.

But it is indeed not something one should use on a daily basis if one wants to maintain one's zero. It does change the surface properties in the barrel quite substantially and cannot be compared with a regular cleaning job, not even using chemical solvents. So using a bore paste will not damage anything but it will take a while for the rifle to settle afterwards.

none of these statements changes my opinion that bore pastes have any place in a cleaning regime

Just dry patch every now and again and that’s it

 

[Dunwaters]

After use push through an oiled patch or 3 until it comes out clean, then a dry patch to take out the oil.
Once a year or so give it the out of the stock and solvent in the bore treatment.
Works fine so far.,

Just come home in disgust. Waited all night for a fox, when it turned up I missed it at 200y, it ran toward me so I reloaded and missed again at 120y.
So the NV scope is off the rifle and my day scope is back on to shot a group tomorrow. I can’t understand how the rifle can be so far out that I can miss a whole fox!
I was shooting of a bench rest with a rear bag so no excuses there - yes it was a little breezy but the last shot was pretty much into the wind.
I must admit I’m starting to despair, I can’t even book a range session as the range will be in Tier two and I’m a few miles away in Tier three. How frustrating is that!

Bore paste? Not in my barrels.

Aggressive stuff that, why anyone would want to do it for no need and remove a reasonable amount of metal i have no idea

It does NOT remove any metal. One of the most persistent myths around.

OK, you got my attention, So what does it do?

I can assure you, it does. Same as metal polish, which is what it effectively is.

It is basically a liquid sand paper...

Owner of Pac-Nor says use with caution, use a poor method & you are lapping

 

[Steff]

Yes, it is a polish. But the abrasives are of a lesser hardness then those in metal polishes. This is at least true for JB‘s.

 

[Steff]

It will polish away anything which is less hard than your barrel. It isn‘t witchcraft..

So what do metal polishers & linishers do when they “polish”metal surfaces?

They will also take off some of the metal surface.
