XS60C - The questions I didn't think I'd have to ask...

[Methuselah]

(WARNING, LONG READ)

First, I just got it a few odd days ago. It was Mike's last one in .177, so I figured either get one in .22 or expect the .177 might be a little rough around the edges.

It was to be tuned, and setting was talked about and I gave it some thrashing around on the phone, that it was to be accurate and back yard friendly. That said, he did talk me out of having it adjusted for low fps and heavier than normal trigger. After all, I got used to the Daisy 880 that was 6#...

So, I've fired it once this weekend at a target about 25' away. Hopefully I'll remember to post the target. It didn't do terrible, maybe .69" with more spread up and down than side to side. Potential is definately there. The stock has a crack at the butt maybe 4" long iirc, and the bolt is really a lot harder to pull back than I thought it would be. It's a $150 gun that's had tuning services worth more than the gun, so I'm thinking I'm way ahead.

It had been fired enough to record some numbers:

Full Power
RWS Hobby - 791
AA 8.4 gr. - 740
Crosman 10.5 gr. - 675
at 68 deg. F.

Accuracy test good

OK, full power. Mike did tell me how to adjust it, but I was thinking lower for less report and better cartridge count.

I wrote Mike back and gave him a piece of my mind :-), telling him I was very pleased and the trigger was perfect too. It's 2# 3 oz., 2# 5 oz. It's pretty loud however and one of my neighbors is the preverbial NFH, so I reckon I'll see how it breaks in, and  try some better ammo before trying to adjust it for lower fps.

My (only) group was ten rounds, CPHP's, of course irons. I don't plan on scoping it, but I suppose that may have to change because I don't see a way to quiet it at the muzzle witout getting rid of the front sight (question 1, can you)?

I've gone to YouTube for disassembly and find you have few vids, all for the QB78/79 which have the same (question 2) trigger group. Nobody did the fps adjustment online and I don't see it here by searching XS60 or QB78 (question 3 --- did I overlook it?).

So I said I wrote Mike. He tells me it needs about 200 shots to settle in, and try feeding it 5.52 H&N's. I don't have much premium ammo, but I have almost one full tin of those.

All in all I wanted my next airgun to be tuned, and I'm tickled pink with what I gots. (THANKS MIKE)

I'm going to put some more of the CPHP's through it for break in, and have about 20 so far. I'm a bit jelous some of the earlier comments of these had LW barrels and reports of same-hole performance at hunting ranges, but who's to say I won't see that. I am impatient and would like to use it with cheaper ammo though, so I suppose it's possible I may lapp the barrel - I reckon we'll just have to see how that goes though as it won't be any time soon.

Is there a dissassembly video or thread around covering digging in as far as a barrel change? I found only one, super long, super boring brit that seemingly built his own tool for pulling the vale body. It had a good tip about not letting the trigger adjusting screw hit the stock on reassembly (shorten that screw, presumably Mike already did).

Again --- THANK YOU MIKE :-)

Amazing little gun!!  I got one in .177  for my wife's birthday a couple years ago and she immediately fell in love with it.  It is amazingly accurate capable of one hole accuracy with open sights.  Who'd a thunk?  Hers is set for maximum shots and seems to hold gas forever.  (It does eventually run out.)  Beautiful gun with no noticeable flaws.  Bolt operates smoothly.  What's not to love?

Nice, yes!

I'm already looking for an excuse to have one in .22 caliber

[splitbeing]

Ftt 4.52s are 8.99 at field supply if that's what it likes and price is a concern.

X3 on Mike is good, buy with confidence

[Methuselah]

So, "progress", a couple more rounds fired, 23 total including the count on the paper with velocities when Mike chrono'd it --- gun went "click" when I pulled the trigger last night.

I e-mailed Mike for suggestions, he said it's empty. Since it also said "Accuracy OK" on the little report that came with it I reckon the count is higher but I did expect it would vent some since the last shot fired the day before wasn't quiet.

I did mess with the cap, it's got a gizmo for bleeding off the charge, and read up some on it, there can be issues. Got PM'd with a suggestion to buy an aftermarket cap without that gizmo, perhaps I will. For now though, I'm going to load one new cartridge (and one spent), inspect the bleed mech, and perhaps let it sit a week with some zip lock bags or saran wrap "bagged" over muzzle and cap to see if it holds CO2.

I find info on XISICO XS60S almost nonexistant, but some on QB78 and Umarex Fusion. Are there others that share the valve and trigger group?

[Methuselah]

So, I've been reading (mostly qb78) and seeing a lot of folks had or have issues with leaks and that it's usually the cap.

I expected my rifle to shoot weak and when opening the bleed it didn't vent anything.

I wiped and brushed out the bleed valve assembly, which becomes accessible after unscrewing the "piercing cylinder". Then added a smidgen of pelgun oil to seal and o-ring.

With one cartridge and two balloons, I expect to know more tomorrow.

I have had my XS60-C for quite a while (August ‎2017) and am probably responsible for many others here getting one. 
I LOVE this gun and have been singing it's praises every since!

I don't think a QB-78 is a good guide as it is a clone of the vintage Crosman 160... However the early Fusion and the XS60 are sisters
 Here is the day I got her from Mike... dependable as an anvil still today.

Thanks for pic Scott 

Mike very kindly also included the front bracket to a D34 clone.

I agree, it's one heck of a nice rifle, and, you probably influenced my purchase. Mine came without scope, but he did ask if I planned to scope it and I told him I was very much hoping to use the irons.

[Methuselah]

2nd cartridge, loaded 1 spent, 1 new. 1 piercing shot, one fouling shot.

First low loner, 2nd and 3rd ccw, next 7 grouped.

Mike DID tell me not to shoot CPHP's, I'm just trying to put some break in lead in the barrel...

Still 25'.

[Hoosier Daddy]

As Mike told you CPHP's are not a good judge of character.
 If you want to break it it in, they are ... well, OK.
But don't judge it's performance by them.
 Get you something from H&N, JSB, or RWS... in a heavy weight for that tune. 

Your post made me dig out my '60
Been months in the safe and she still held a charge.

I know you're right Scott. I've probably got most of what you suggested.
AAMOF, 15 yards, one shot, FTT - dead center hit.

I'm just taking my time ... wanted to see if it holds CO2 first and let the mechanicals settle in.

You could post a target...

I might have some XS 60c targets posted in the hunting gate

[splitbeing]

A co2 gun I got from Mike came with upgraded orings he installed, including in the cap. Different gun than yours. Mine's a qb family gun. No leaking issues with the qb family gun from mike. The qb gun I didn't get from mike has needed new orings and had leaks a couple times.

[Hoosier Daddy]

You could post a target... 

This is one I have on file from back in the day that is relevant to my point...30 yards.

[Back_Roads]

 Mine was the answer to a rabbit issue at 25 yards DRT with significant brain damage, shooting 16gr Poly-Mags.

So far 15 shots on a single cartridge, last one sounded anemic (full power tune), miss at 15 yards with h&N ftt. Still talking break in though.

(Holding my breath...)

Polymags 
I have them in .25 cal, might just get some!

[Methuselah]

Again 25', H&N FTT 5.52, around 20 to 30 count in one cartridge, 10 rounds. First went high, just left of group rested on hand on bag, other at low left is a mystery flyer. Frustrating, but 200 rounds for break in, ok.

Modify still works ... shot 17: 582 fps, shot 31 (after that group): 464 fps.
