Tuning Umarex Gauntlet Problems .22

I would like to see Hajimoto, address the hard closing bolt issue. First off I don’t think the G2’s with this issue would give him accuracy.

I have addressed this issue in another post which you may find useful. Keep in mind that any of the services offered in a complete Tune Package, are also available individually for users that only have one item they wish addressed. 

I hope this helps.

Thank you so much for posting this reminder. I know a number of Gauntlet 2 folks are wrestling with this problem. I had not run across your previous posts about the issue so I appreciated your posting. Since I am not handy enough to do the required polishing, I will do the correction the hard (or easy) way by just shooting until the smoothing and accuracy improve. I primarily use JSB 25.39 grain pellets, so it make take plenty of magazines to accomplish the deed but I am a patient person.

Thanks for the suggestions. And thanks for your effort for the airgun shooting community. My Gauntlet 1 is still purring along thanks to your 'big bottle' and Ninja regulator adjusted to 1900 psi.

Hi Radduci 

I just got my Gauntlet 2 back from Umerex. My results weren’t productive. I didn’t receive any correspondence, other than a test target, with a .56 and a .61” group at 20 meters. That’s not much better than I told them that I was getting at 50 yards, if you do some math. The best group I got out the gun, was shooting “weight matched” JSB 18.13’s, into a 1 5/8” group at fifty yards. Ten shots with six bulls on a one inch bullseye. A .56 group at 20M, calculates to 1.3” at 50 yards. Not a big difference. So I shot the gun, and found no improvement for our, mine, and Umerex’s efforts.

Hi, .20calguy; Sorry to hear about the return of your Gen 2 with no improvement. My result was basically similar. Fast turnaround but nothing significant changed. I read Hajimoto's comments about the causes of the need for a hard thump to get a pellet into the breach and found it very interesting. It makes a lot of sense, as did your appraisal re the rifling. Haji also spoke about the reasons for the hard chambering..... short lead-in to the barrel and the condition of the rifling at the barrel entrance. There is no doubt about the short lead-in and the condition of the rifling at the barrel entrance, as you also said. I am shooting indoors and probably will continue to shoot indoors using a combination of 4 magazines of Crossman pellets followed by another 4 magazines of JSBs to try to wear down the rough edges. Those hard Crossman's are beginning to make some inroads to wear down the roughness. The JSBs now chamber a lot easier but it will take some time. The grouping of the test shots Umarex sent to you look pretty good to me. If you are getting groups like that at 50 yards you are doing well, IMHO. I was lucky to get 2 inch groups last time outdoors at 60 yards. That was before I started shooting with hard Crossmans. It will be awhile before I feel ready to shoot at long distances again. It will take a lot of lead to polish up the lead-in and the barrel entrance but I have time and winters are long in Wisconsin so shooting outside is not very attractive up this way for a few months. Any plans to improve the Gen 2 yourself or send it for professional work? The end price of the Gen 2 may be a lot higher to make it better.

Hi Radduci, the picture of the groups, show the Umerex test target at 20 meters, or 21.87 yards, and my 1 inch black dot targets, at 50 yards, which is 45.72 meters. I shot those groups yesterday after I received the G2. I’m not sure what the two low flyers were about? Those pellets were sorted, and weighed. The regulator fps’s were amazing. All 977’s with two 979’s, and one 974, which could have been the low guy, if I’d have been paying more attention. After running out of those pellets JSB 18. gr, I ran about eighty Barracuda Match 21.14gr, and they didn’t shoot well at all. 
as far as repairing this gun or letting it break in, I’m inclined to send it to Hajimoto, and have it done right. I have been watching and reading all I can find on his work, especially G2, related. I’m sure I’ll have a happier “my gun arrived” message after he worked on it. Lol in the meantime I’m going to shoot it. I’m in SE Louisiana, and this is our best BBQ weather, usually until after Christmas. Nothing goes better than BBQ, and pellet guns! Just don’t get confused, and keep yo hands washed!

Hi, again, .20Calguy; I would be happy if I could get a group like that at 60 yards with my Gen 2. Even at 20 yards, mine won't consistently group like that. I'm not the best shot in the world but the comparison for accuracy between my Gen 2 and my Avengers is staggering. I've not been unhappy with the velocity and fpe measures I've taken with my .22 cal Gauntlet 2. Velocity stats averaged 1023 fps with 18.13 JSBs and 914 fps with 25.39 grain JSBs, fpe of 42.2 and 46.6, respectively (I only fill to 4K psi). Accuracy, on the other hand, has never been very good. I have given the rifle a good cleaning and will do it again after I shoot the cr*&p out of it with Crossmans, but am not sure how much better it will get. Your decision to send it to Hajimoto is a good one. I would also do that except shipping cost for me, even with UPS ground is about $40.00 so round trip would be about $80.00. That's a significant add to the price of the rifle. I can buy a lot of pellets for that much (if I can even get pellets again, with the delays in availability. Fortunately, Crossman are cheap and will hopefully stay available). I could pull the barrel but but would also need to pull the breach block and I'm not keen on doing that. Shipping cost would be cheaper for parts, only but there would still be a shipping cost and the mod is priced at $110 or something like that. Again, I just don't want to pour more good money after bad. I may change my mind later at some point, but for now the economics just don't make sense to me. By the way, lucky you on your location. Temps are running in the low 30s and we've already had some snow flurries here in Wisconsin. My taste for outdoor shooting is waning rapidly. The months ahead will allow plenty of indoor shooting time so we'll see. I do like your combination of BBQ and Pellets . Also, proximity to DonnyFL 'ain't bad, either.

Hi radduci. 
I wanted to mention that I discovered that my rifle was dropped here, before it was shipped to Umerex. When I examined where it was dropped, I spotted two dings in my flooring. I grabbed the rifle, and laid it on the dings, one lining up with the muzzle, and the other with the air reservoir. So I apologized to Umerex, and removed those comments and photos, publicly. 

.20Calguy; Sorry to hear that. Hard physical impacts are certainly not good and can explain a lot re the performance that you have been experiencing. Hope you can figure out how those ‘drops’ happened. Are you going to do some testing before asking for a swap out? I no longer have a cat but could always blame things like that on the kitty
