CK you're shooting at open class FPE, right? Have you tried lower power to see if there would be less barrel leading? Maybe JSB Monsters at HV would lead up less.

Haven't tried the other barrel yet- with the lighter pellets.
but from others- I'm told the same leading is taking place, even using 8 grain pellets?
ive talked to several people about the fouling. All say it's par for the course with the polygonal barrels -
and all clean their barrels after each card_--
guess it is what it is?
I was also told by competitor - everybody has a secret sauce - so to speak- not wanting to devulge their brews --
give others an edge?
Makes me laugh though---

If there air is coming from between your breech and valve body it is likely a power wheel oring. If it's not that then it's the seal between the valve body and breech. Depending on when your s500 was made you will find an oring or nylon washer. Mine has the washer and is quite rugged.
To check the power wheel orings pull off the stock and next to the guage block you will find a hole. That is the tension/pin lock for the power wheel. If i rember correctly .5mm allen key is needed. It could be 1mm though. Anyways back the screw out and carefully turn the gun untill the spring and very small pin fall out. Then gently pull out wheel. As for the breech there may be two or four screws ahead of the trigger group and two more behind it. Remove those and you will have access to the valve/breech seal.
I hope this helps you out. John

I have a RAW BM500 177 poly shooting HV. The accuracy doesn't seem to vary noticeably with cleaning routine or frequency.
I normally pull a dry patch before each card - which seems to be what most BR shooters do. I also tried 20+ wet patches (WD40), which is about how many it took before they stopped showing lead. However even with this aggressive cleaning it shot the same as with single dry patches, and there seems to be no disadvantage to leaving some lead in the barrel.
As they say, YMMV

Changed to my 1000 pound bullet trap. Found that pellets were going through the small rubber mulch filled box and going 100 yards - and blowing through the back stockade fence! Also tried separating the cardboard backer from the plywood in hopes of getting cleaner holes?
And this is card three before scoring plug was inserted - seems like some of the pellets are tearing the holes slightly now that I'm using the cardboard backer?
and today was was extremely windy, gusts to 30 mph- not a great X day - 49 and a 750 though
'and yes I shoot open - at 27.6 FPE
28 yards
Cheers

I don't have a poly barrel but had good luck with pushing patches soaked with Ballistol though and giving it time to soak. Then pull a Hopes .177 bore snake though to dry/remove lead. It's way bigger than .177 and takes some real effort to pull though so lots of contact and pressure.
I'm getting a new barrel (the chase for best accuracy) and will try using a different lube on pellets with that barrel. I'm told I shouldn't need to clean lead if I use soaked pellets versus me drying them like I do now.

For clean holes you can use the plastic realestate signs for a backer. I'm sure you come across them often enough. Another trick would be to spray glue them to the carboard you get from frozen pizza boxes cereal boxes and such. Something else to try if you are using official card stock taregets might be spacing them off the backer so the regular carboard doesn't interfere with the card. As always great shooting. John

On the cleaning issue, dry or wet your patches should be tight enough that it sounds like a sick goose honking when pulled through.

I tried the balistol in the beginning - after giving up on the original recomenation of WD -40
the biggest issue with the barrel is the Choke, IMO - very tight, and the JSBs are very soft- I think of it as squirting toothpaste out the barrel
what I've learned is that scrubbing,soaking patches and solvents only get at the surface leading. So this in turn causes a couple of WTF shots- per card -
but once I determined a way to completely remove the lead from this barrel and bring it back to virgin state, now when I do my cleaning after each card, the patches have only a hint of lead on them. I know that after 100s of shots,I will more than likely need to do the heavy duty lead removal again --
hell I even tried lubing pellets - awhile back- this barrel really didn't like that! Was like a shotgun.
i don't believe that in all my years - I've seen such a barrel -
guess you could say, every Rose Has its Thorn -
'the choke/poly is the reason for its accuracy but at the same time/ the reason for the extreme fouling

Thanks John - I'll have to get some of them. But plywood only was causing really jagged holes- so I figured the cardboard backer was the way to go,and give it an air space from the plywood, but it seems at times to makes the holes even more jagged?
lots of Schitt to deal with!

I had the option of trying the poly but decided to pass this time around as see I lots of BR folks talking about it, but don't see alot of FT tolks going after it. That plus the leading issues you guys are talking about has me going to a new top end LW match barrel. Hoping for 3/8" at 55 yrd this time around...

I like the accuracy of this barrel,but really wasn't prepared for this cleaning routine - or the need to dig into my brain for an old world toxic substance to remove leading.
I've shot 6.5 swedes - 600 yard matches and swabbing the barrel after each shot was a standard --
but never - in all my years have I seen fouling like this,and after 25 to 30 shots no less-
but Hell it is what it is --

CK, I use an EVA high density foam gym mat as backing up against steel sheet. The pellets stay between the mat and the steel and all spatter is also captured, leaving the cards with clean holes and not 'fragged'.

Yes - and several other lubes - but as with the Kryteck - caused erratic pellet performance -
truly a fickle barrel?

Wow, I've used WD 40's specialist line of Silicon spray and Duponts white teflon with good results. Those are the top 3 I've found.
That barrel must need to really grab the pellet solidly to get it's accuracy.

Hadn't thought about a rubber mat. But since I have a firearm bullet trap - it's capable of stopping .223 ammo -
'and I do shoot .45 cal ACPs into it -
but thought - just using a cardboard backer would Create more concentric holes?

I do believe so, Sharroff
the choke is probably shaving the pellets slightly - and pressing the swaged pellet into the valleys of the barrel
With polygonal think hills and valleys instead of lands and grooves

If you ever get tired of cleaning that barrel, send it my way. I'll be happy to scrub it. Nice targets....as usual. I sure would like to be able to do such a nice target, but then again, I would probably get bored shooting 750's.......ya right(sarcastically).
Excellent shooting CK....
