Barrel "Conditioning".

[Keith Oakes]

I've found my HW100 performs superbly with 16gr Logun Penetrators. I was shooting disc targets out to 40yds with deadly accuracy. I've always used H&N FTT but I really get on well with the Loguns. I haven't grouped it yet but I am going to sunday. I'm pretty sure I'll get good groups but the proof is in the pudding as they say........

I'll keep you posted

Is this true of springers as well as PCPs?

I don't know the definitive answer to this, but it is true for PCP's and rimfires, so there is every chance it is the same for springers.

Definately. I've a couple of highly tuned TXs that shoot like shotguns for the first dozen or so shots after a good barrel clean (which I never normally do for partly this reason), and takes another 20 to get really good again. With some particularly highly polished bores (career) it is far less pronounced. Polishing with JB can also help.

This thread saved me from going mad, thank you Neil.

I had done some tuning work on my .22 QB78DL and decided to shorten the barrel as well.

Previously this rifle had shot very respectable groups but after shortening and recrowning the barrel it was all over the place. I skimmed and recrowned three more times , and tried various different pellets, all to no avail.

Then I read this thread. I thoroughly cleaned the barrel (never, ever having been cleaned before ). I even used the brass wire brush from a Bisley cleaning kit. The filth that came out was shocking. This was followed by pull through patches treated with Youngs "303" oil (just happened to be what the gunshop had in stock).

Next I put 20 RWS Superdomes through it before trying to zero.

I could not believe the difference. Better grouping than ever.

Thanks again Neil for some superb advice.

Cheers, Mark.

I have just, this morning, shot 3 different types of pellets. My Tau7 Co2 .177 pistol was stuck nicely into my workbench.

Shot outside at 10 metres


Pellets shot:
Match Kugeln
Match Finale
D/N Gecos, sized 4.51 & unsized (the unsized groups have probably done artificially well, as I didn't pick up one that needed a real thumb in, like they often do.

I shot one sort, shot the next etc without cleaning. Then I went thru them all again, cleaning the barrel just with a brass brush, between each sort.
The results speak from themselves!

By the way, I know you might think I need to shoot hundreds more here, to be scientific, but there's definately a pattern and I did shoot several sets of each, before and after, which I didn't include as they were pretty similar results - call this collection a summary.

THANKS NEIL

Any comments gang?

Well, I think these results speak for themselves, very graphic.......

What an improvement in grouping.

Got a bsa r10 and tried allsorts of pellets and found the only thing it would group were bisley mags but now after about 1500 pellets is starting to settle down with aa field after cleaning the barrel with a bisley cleaning kit

so it definatly did help cleaning the barrel

I always clean the barrels of all my rifles after about 300 shots, sometimes sooner, I then need around 10 pellets put through to settle the gun as you say Neil. Some people think I overdo the cleaning, but I find it works for me, in fact I definitely get better groupings when the barrel is clean.

I also clean and lube all my pellets that I am using for zeroing or hunting/competitions. I could maybe not do this now as the quality of the best pellets is very good, but I started doing this process years ago and it works for me.

[Kerry89]

Thank you.

Very helpful

[XS208]

Great information! Thank You - I thought I was losing my mind or the ability to see properly through a scope

[Alan Bale]

This might solve a few of my accuracy issues too. I will have a look when I get a chance to spend half a day on it. Good advice Neil.

Then again, I might just be a rubbish shot...

[Goodguyj]

Does it matter which pellets I'm using?

[dirty harry]

exellent thread, never even thought of that but when you think about it it makes perfect sense, different lead grades and batches will slightly coat the barrel and end up with a collection of different grades causing slightly different drag factors inside the barrel i would imagine.
