Interesting rimfire cleaning theory and method

[littlesister]

Thats been my results so far. Nothing even maybe changed. I always do a test multiple times but in this case it was so the same I'm not sure its worth it.

I didnt know you could do a true coned breach in a vudoo with out dryfire concerns. The RimX typically has the flat and a slight cone. I rebarreled with a true coned breach in mine now and It can cause issues with dryfire.
If I can do that with a Vudoo effectively then

I don.t believe the Vudoos came with a "Do not dry fire warning" so they probably took care of that problem with the pin stop and also some cone breach shapes don't damage as easily as others. I had a Lilja barreled Annie with a cone breach that you absolutely could not dry fire without damaging the cone! Ask me how I know?

I actually tried finding a good gif but I couldnt find anything... appropriate.

I loved that movie

Very interesting to see the raw data. Thank you.

I just had similar results within my first 500 tested over the Chrony with a new barrel earlier this week with a gain of 40 ish fps. Over the next 500 or so im assuming you expect velocity to stabilize but potentially sd’s to shrink slightly?

so you try an avoid until a problem occurs, now does that include bore, chamber (carbon ring), and muzzle or do you tackle the carbon ring and muzzle and leave the remaining?

This lot of ammo i've used quite a bit. The SD are higher in this barrel then others so far. Give it another 600 see where we are at. Its also a slightly larger headspace then I'd like at 0.046" maybe this plays a part too.
Carbon ring doesnt change my POI at 50 enough to make you notice with my other Barrels. I have had a high velocity first round after that it will show up on paper at 200. That seems to happen clean for a bit then after a 1000-2000 rounds. I dont have that pegged down yet.
This one built up a ring faster then the others but its to early to know. This barrel has a near perfect smooth chamber, leade finish. I've wondered if those carbon up more then ones with slight cutter rings.

I clean the chamber and muzzle then run 1 patch through to get rid of any gunk blobs or cleaner I may have got into the bore.

Your new barrel. I saw more velocity increase with my barrel thats same as yours too then with this one.

Excited to hear your finding on this new barrel! You got to work on it pretty quick, didn’t Den only drop it off Tuesday!

I’m just waiting on my deuce before I spin my ks 1:10.

Hmm you and him must talk. I'm keeping under my hat for now lol
650 rounds so far. But this is getting of topic.

It doesn’t matter if people agree or disagree with the hypothesis, but I want to make sure people understand the concept.

IMAGINE THE FOLLOWING

Pretend If:

• Every time a rimfire rifle is thoroughly cleaned, it becomes less accurate/precise
• It takes 1000 rds to re-attain previous groups
• Those earlier groups were tight enough to win in a certain shooting discipline

And if that shooting discipline:

• Has stages that require 50 rds shot in succession
• Disallows cleaning mid-stage
• Disallows shooting of any form between stages (to refoul the bore)

Then:

• A shooter in said discipline should not clean between stages or even between matches unless they can shoot another 1000 rounds (carbon ring removal excepted)
• They should wait until acceptable-per-discipline accuracy/precision degrades before cleaning (unless they can’t help themselves lol)

It may be that the accuracy/precision of a rimfire rifle with 1000 rds down the pipe is not good enough to win in BR, but is good enough to win in PRS, and that cleaning frequently in PRS leds to lots of fliers because shooters can’t refoul the bore to acceptable standards in the time that they have.

And: acceptable accuracy/precision are RELATIVE (not absolute) concepts here. Relative to certain shooting disciplines.

That is a lot of pretending.

 

[Gleedus]

That is a lot of pretending.

But a reality for many of us

 

[carbonbased]

That is a lot of pretending.

Take a peek at non-Euclidean geometry (summary). At first glance it looked like a bunch of pretending too.

That’s how science works…one comes up with a hypothesis and tries to see if it plays out. But if a critic doesn’t understand the hypothesis, he cannot intelligently comment upon it, right?

I’m not saying what others have postulated is true. Again, remember, this whole cleaning regimen thing is not my idea.

 

[carbonbased]

And to follow up, this is not a debate of words. Once someone adequately understands the concept/hypothesis, the only debate is in the field. In other words, to test it correctly and with an open mind.

I mean, that’s it. There should be no ego involved. Who cares which bore cleaning method is proved to work best in a certain discipline? Psychologically, what could possibly be at stake for such an insignificant thing?

Unless…one is OCD and cannot bear the thought of not immediately cleaning a rifle…

 

[RTH1800]

I did not criticize you. I really do not care what, how or if anyone cleans. I know what works for me.
I simply find that when I’m told to start pretending, I check out.

Fair enough.

First break-in 50 rounds at 50yds, cleaning every shot. Rifle groups incredible with its 2X scope, great for squirrels.

Great looking rifle!

I love the look of that rifle.

Opening up an old can of worms. Curious if anyone who has been using the C4 chamber cleaning only method with a well seasoned barrel; scrubbed the entire barrel clean to find accuracy and consistent velocity drop off?

I like the thought of only using C4 for easy chamber cleaning but....
