New hammerli 850

[Bullit]

Good Choice Steve.  There's good potential with the 850, and it's fun to shoot.   You might look at a larger tank conversion while it's getting worked on.  He can fix you up.   You'll get better consistency, more shots, and save a bunch on fills over the Co2 cartridges.
The Co2 tank conversion, is relatively cheap for what you'll save. Thumbs Up!

Your set now Steve. Roald is the master with 850's. I personally did not know he was still tuning them but that is great news. Best of luck.

Trust me - NOT everyone wants to convert an 850 to HPA or anything - it's dead nuts accurate & great to shoot - You want a HPA - fine, buy one.

[stevemag]

not interested in hpa at this time. i have a few 88 gram cartridges left till i decide. i just dont like the look of the bottle sticking out the front.

On the 850 it the 88gr cylinder doesn't show - what did you buy??? - Once screwed in, you slide a cover over it ... what's the problem now???

Many air gunners don't like the bottle look. The 850's are very accurate and Roald has done a fantastic job of promoting their full capabilities, either stock  modified Co2 or the HPA versions. I chose the HPA version and really enjoyed it. My only complaint with the Co2 is I have no place to target shoot in the winter and I decided on the HPA conversion. CO2 is great when the temperatures are right. I like shooting all year round though.

I'm talking about if I convert it to a 9oz bottle or some sort of refillable 88s

In the cold weather I can shoot at ten yards indoors , and your rifle looks pretty good even with the bottle. Maybe I can give the bottle a cool paint job .

I use the 850 in an indoor winter league, - took second place with CO2, no problem. - Now even trying to use it outdoors here in the winter is a totally different matter, - probably not so great at about 12* below. ... LOL.

If you want to get around using the 88g's you can pick up one of the O.E.M. 2x12g adapters. They can be used with the cheap 12g powerlets, or you can leave out the 12g's and just bulk the cylinder by using a cheap Walmart adapter that is easily modified for the purpose.

Do want to show you something about RWS 850 barrels. 

Had a spare .177 RWS 850 barrel hanging around from a trade deal (think the original owner converted to .22).

Had a Crosman 2260 co2 that wasn’t shooting well.  Rebarreled it with a “mystery barrel” that come from I don’t know where.  LOOKED like it might have been originally from a springer.

When that didn’t work out, grabbed the RWS 850 barrel and fitted that to the Crosman action.  Ran it on co2 for a time, then converted to PCP by way of a HiPac unit.




Had to make a thin riser to get the fat barrel up off the air tube, HiPac as a power system, worked well, and genrally just fiddled around with getting the valve to run well (“well” in this respect means smoothly and uniformly) at 12 foot pounds.

Was testing a new (smaller) LDC Sunday and did find the groups were very slightly lower. 





Lower first group was most likely due to the barrel vibration and the new  smaller/lighter LDC.

Whatever else the RWS 850’s are, it does seem to put very good barrels on them.

I hope my barrel is that good, Roald assures me when it comes back to me it will. Looking forward to getting it back.

Heard from roald at the 850 store today and the news wasn't good.
seems when they made the hole for the front sight they almost punched all the way to the bore. causing a ...lump, for lack of the right term, in the barrel .  Roald says this is common for refubs in .22.   this was the cause of my accuracy problem. only one solution, a new barrel.
so far ive spent more than if i bought a brand new one , BUT when i get it back i will have a tuned refurb 850 for about the same price as a new tuned 850.
more than i wanted to spend but not a money pit, still about 25 bucks ahead. oops, never mind, forgot i had to ship it to Roald .so im even.

[dk1677]

Well that stinks Steve  , but you will get a very good one back

[stevemag]

first and last refurb i ever buy.

[stevemag]

i was gonna say, someday ill get one of those great guns right out a the box like i read about but then i remembered my xs25 from MM . great gun

Maybe this a newb question....  But why can't he cut off a couple inches and recrown?

i guess he could but then id have no front site, probably cost about the same anyway . a new barrel is $60   ill save it and learn how to do t myself and ill have a carbine barrel

[fivestar45]

Been there, done that....I hope that your replacement barrel is better than the one Umarex sent to me.
The sure way out is to just cut and crown the barrel. Neither of the barrels that I had were choked.  I also use iron sights (Williams Peep) all that's necessary is to drill and tap a hole in the top of the barrel (properly) for a front sight screw.
And in this case I doubt that a "New" one of these rifles has any better chance of getting to you with a good barrel than a referb. This has been an ongoing problem with Umarex that they are aware of.
If you call them, they will give you a RMA for the barrel, and replace it N/C after inspecting yours. At least that's what they did for me. Again, the replacement had the same dent in the I.D.

[vigilandy]

I just thought of something... if you cut it, then can't get a warranty replacement.  May be past the 30 day mark anyway for a refurb.  I got mine from AGD as well, but it's a 177.  Haven't even had a chance to shoot it yet!
