Gamo Urban Groups (updated info)

[Ken13]

Agreed. Here's a group at 50 yards from before I dropped the power. The flier was my fault.

That's better than my 33 yard group. I want to try 50 but I feel like I'd just make a mess of it haha

That’s a good group! Keeper

What are you guys getting for velocities?

I’m regulated shooting low 800’s

What was it shooting before you regulated it?

Paul, those two 35yd groups show a peculiar bias of horizontal stringing.  Since there was no wind to speak of, maybe put some attention on the barrel band.  I don't know if the Urban's band is designed to be tight fitting or just a guard, so to speak, but I think those groups are trying to tell us something.

Thanks Jason.  It does have a screw that can be tightened, I'll have to check to see if it's loose.  I have a replacement coming from Walmart, it should be here Friday, so I'll see if it's any better than the one I have.

No problem.  FYI, probably half of the barrel bands I encounter will not snug up when the screw is tightened.  Whether or not that is by design is unknown but it's a good idea to try it both ways when dealing with a persnickety rifle.  That is, try some groups with the barrel band removed.  And then again with the barrel band nice and snug.  To accomplish that, wrap clear tape around the air tube and/or barrel until the barrel band is a slip fit to both of them.  Then when you tighten the screw, it will snug up nicely.  The benefits are well worth the effort.

I'm low and slow in the 660 range. If it is calm or steady winds, no problem, but if they gust or swirl it is a completely different ball game. Once the spring winds get here I may crank it back up but I also keep reminding myself there are a lot of folks in the EU that get very good results with 12fpe. The longer barrels on most of their rifles may be the largest difference.

I shot a bit today with winds steady at 15 gusting to 22. They are mainly a headwind that caused about an inch of drop at 50. When the gusts hit they would swirl and push up to 2 1/2 inches either way. Managed decent groups once I got used to the wind, nothing to brag about but it was relaxing just to look thru the scope after a long day of work.

I checked the barrel band, it seemed snug, but I tightened is as far as i felt comfortable. It's plastic so I didn't want to strip the threads.  There is a rubber o ring under the band that surrounds the barrel, so I'm guessing it should be snug.   I guess i'll see tomorrow when I shoot it again.

I've discovered that it's loosing air now also.  Might be from when i removed the gauge because it wasn't working at all.  Now it seems to register to 2000 psi, but doesn't move beyond that point , even when the gauge on my pump shows 2900 psi.

Glad you got a replacement coming. Would like to see everyone as happy with this gun as I am.

I’m regulated shooting low 800’s

What was it shooting before you regulated it?

Depending on pellet weight 840’s to 880’s

I second that!

I don’t know if losing air is the culprit. If you leave it coupled, does your hand pump drop to 2,000?

[Rat Sniper (AKA: PaulT58)]

I say it’s losing air because when I finished shooting yesterday, I aired it up to 2900 psi according to the gauge on my pump.  The gauge on the Urban said 2000 psi.  This evening, the gauge on the Urban read 1000 psi.  Hopefully, I’ll get a chance to mess with it tomorrow evening and will see what the pump gauge reads.

I recieved mine from Walmart this past Friday. Scoped it and ran it on the chrony- have it set @ 860fps JSB 15.9gr. For 25 shots with a 32fps spread. It's very accurate. Performed the 2nd stage trigger mod which is a must. Great rifle for the $$. It's quiet to. I'm thinking about buying another one. Lol.

Can't ever have enough of a good thing!

I haven't done any groups with either of my Urban's since last summer, but I did see a few 3/8" groups at 50 yards with the first one I bought. Good to see that y'all are getting yours wrung out and discovering the 'best' pellets. I haven't tried a whole lot of super-heavy pellets, but the 18 gr JSBs were awesome outta mine, too..

:-) chickie

Guess everyone had luck with those but me haha -ken

Air guns can be funny like that, Ken, lol...

I once had an R7 that hated JSBs of any weight. Shot RWS Super Hollow Points like a laser, though.

Yeah, air guns sometimes be weird like that, ha ha!
