New hammerli 850

[stevemag]

I know a lot of hammerli 850 refurbs were bought last week or so. I received mine in .22. 
Mine came with a magazine without the o ring and the rear sight broken . After a few emails back and forth with no luck I  sent a pm to Scott here on gta and he got right on the ball and I should have a sight and magazine here soon.
I put a scope on her in the meantime and found an oring for the magazine so she's up and running.

Perhaps I was just expecting too much after all the rave reviews,
I have a qb78 that shoots several pellets well and shoots super domes under a 1/4" at 10 yards.
I was expecting the 850 to do better, if not at least the same.
So far I've found one pellet that shoots as well. Most pellets performed badly, 1/2 to 1" at 10 yards.
I get just about 150 shots from 1 88 gram cartridge
Power is just about equal to my 78 , but ill chrony it tonight.

The stock.  Smallish, and kinda skinny, at least the butt stuck is to me, the combs not high enuff even with my low rings and 32mm scope.
Bolt functions smooth and the trigger is very nice, a little long but light, i haven't done any adjusting to it(assuming I can)
I'll do some more testing of pellets today if I have any more types, did about a dozen,
All in all I'd say it's a good alternative to a 78 . Except on 88 gram cartridges it cost twice as much to run it.
I always found with my 78 that if i wait 30+ secs between shots my groups really tighten up. Seemed to help a little with the 850 as well, although that kinda defeats the purpose of this multi shot repeater.
I'll post a pick or 2 later.

Mine likes RWS Super H Points , check out  the 850 store on the yellow

I think I have some of those, I will try them today.
If I decide it's a keeper I think I'll have to bottle feed it and put in the heavier hammer spring. Just to give it an edge on the 78.

I have one in .177(non-refurb) and I shoot it all the time. I kept mine stock  (maybe 8 or 7 fpe) and she has no problem picking off pigeons @ 40 yds. Try shooting JSB's

You're gonna like the 850, ... I enjoyed it right out of the box, it was shooting low 600's at the time. - After I sent it to the 850 Store for a tune, (and tune only) - now low 700's and dead-nuts on.  ... If you can do it I would strongly recommend a tune  at the store - you won't regret it. ... So far as pellets - who knows, I took second place in a winter pellet league shooting these.

it seems to be EXTREMELY pellet fussy. it may be a deal breaker for me. i could see 1/2 groups on average at 10 yards, with a few that shoot very well. but this is shooting 1 pellet at 3/8 and the rest at 1-1.5"   i feel that an air gun should at least be able to hit a soda can at 25 yards with just about any pellet . but so far this gun hates everything but one jsb pellet.

I picked up a new one for my FIL last year and on his when you cock the bolt it will hang up as you push forward unless you put downward pressure on the handle.  It hang so badly that you have to use excessive force to push it forward unless you put some downward pressure on the handle.

My FIL shoots it so little he is OK with this.  If it were mine I would tear it apart to see what is hanging up in there.

If my memory is correct his shoots 22 cal CPH's at around 650 fps.

[North Pack]

I haven't found the 850 to be fussy at all, - CHP shoot pretty good too and another one I don't recall at the moment. - For the money involved - tops imo.

[stevemag]

the general rule of thumb for pretty much every purchase i have ever made  of anything...if there is one out there that not worthy, i'm gonna get it.

I  bought a .22 cal 850 about a year ago. I proceeded to take it apart to make a few changes, and just check things in general. The only real problem for me was that the barrel had a dent in the bore that you could feel when pushing a pellet through it. The dent was at the muzzle end right bellow one of the front sight screws. I called Umarex and sent the barrel to them. After they inspected it they said they would send a replacement N/c..I asked them to check the replacement barrel before they shipped it, no problem we'll bore scope it prior to shipping. A few weeks later the new barrel arrived...complete with front and rear sights, and the same dent in the bore that the OEM had. At that point I just cut the barrel at the obstruction, and re-crowned it. I did however send a pic of the very visible dent in the bore to Umarex they agreed that it was n/g and offered to send another...if I paid for it.
The punch line..if you have the same bore dent, it just may be the cause of pellet pickyness.

chronyed it tonight. 625fps with 14.35 grain jsb pellets

I bought an 850 NEW about three years back and converted it to hpa. It shot JSB's with quarter groups at 30-40 yards. Very consistent. I liked it so much I bought another one which was used after I sold the first one. I will convert it to hpa as well.

have about 300 pellets through it so  far.  i wonder if having it tuned at the 850 store will improve accuracy? if so its worth the investment to me. i was jst hoping this would be a very impressive shooter.  it IS fun though.

[supertech77]

my 850 was a refurb,still is,lol.anyway darn thing loves the cheap pellets i bought from mike melick,and the cheap tech force, 22 cal pellets,i have a bunch of other type pellets,all different brands and weights,but shoots and cycles these best, shoots the cpdp good but they don't cycle well due to the shallow skirt,s i put a 13Ci bottle on mine and did all the mods, and even got it on hpa now, with the 13Ci ninja bottle that b stern was raving about, 730 fps on warm day on co2 875 to 910 on hpa with the 14.3 cpdp,it also shoots the eunjin 28gr well but you loose 175fps,very accurate with them and the 18.3 exacts as well, but all other pellets than what i mentioned and there all over the place,mod,s are easy to this gun with the 850 web site instruction,and i remember gene's red gun, sweet looking 850,try those cheap ones from mike,it surpized me,too how well they shoot,after one can i bought about 6 more, and some tech force too, still got a mess of them, pm me a address stevemag and i will send you a few,over all once you work out the issue's with it they really are very sweet guns,

Check 4 things.

1. OUT of the stock (will have to be empty, no co2 bottle attached to get it out) check the barrel/receiver joint for "wiggle".
2. Will need a pair of tweezers (or the like) to load it single shot, but if it does better as a single shot than a repeater, would point to a magazine/indexing problem.
3. Take the detachable part of the forearm  (the bottle cover) off.  It hangs on a dovetailed barrel hanger, and can do odd stresses to the barrel.
4. With the scope off, cup your hand around the mag/breech and feel for puffs of gas as you fire.  If something is leaking, chances are it's not leaking uniformly.

I got one of the 850's from AGD, box was labeled wrong so I have a .22 instead of .177 Haven't got to try it out yet.
A fellow named Jared is offering single shot trays in .177 and .22 for the 850 and 1250, $10 for one, $15 for two, looks very nice and fits in the rifle perfectly.

[stevemag]

thanks ribbonstone i will test tonight.
dave that single shot tray looks interesting. i may have to get one .

[stevemag]

did some tests tonight, took the for end piece off and got excited when the poi changed about an inch...but groups remained at  about 3/8 to 1/2". tried several pellets.
next i fed them with tweezers into the chamber with out the magazine. thought that was it but still getting flyers, maybe 3 in the same hole then 1 went 1/4 inch right then 1 went 3/8" left. also did a tissue test and it passed.   so my results were really inconclusive.
just to be sure it was not me, i got out my qb78 and shot a few groups at 1/4 inch. next thing to do would be to take it out of the stock and see whats going on there.

[stevemag]

Just  came from FedEx and the 850 is on the way to Roald at the 850 store, just getting the full tune . Since I got it so cheap I figured I'll still be a head of the game. I would have been annoyed if I payed full price and it still needed a tune. Still haven't decided how to power it yet.

[North Pack]

Ok - You're gonna be all set now, - just shoot it any enjoy it, ...
