The Gauntlet2, Bench rest @28 yards.

Some of you may know that I have Gauntlet2 that I have been disapointed with since I've owned it. I have allready returned it, but Umerex was happy with its accuracy, and sent it back to me. I just thought that a rifle aught to be able to out shoot my pistol? To fix my problem I purchased an Fx Crown Mk2, and kept this guy to learn on.
I want to mention that my G2 is not representative of all G2's out there. Some folks have great shooters.
Right now Im intensionaly shooting coarse ammo in an attempt to break in the chamber chamfer, which didn't exist when I got it. This idea was passed along by someone who knows Gauntlets. Besides I'm ejoying it, and the guns is improving.
I had purchased a couple cans of Copper thinking that those should be harder than Crosman's. One of the tins shot awful, and the other shot as good as i've seen this gun shoot.
The awful ones were Excite Spitzkugel's Giving me a group of 4.5 inches at 28 yards, 153 shots
The others were H&N Baracuda Power. They shot about an inch and half, with most centered and fliers around the perimeter. The Baracuda's were good enough that I could get off the paper and do some plinking.
Next I'll shoot all of my Crossman and Benjamin's, then clean the barrel meticulously, and shoot some JSB 18gr, and see if we're making progress.
The gun is in its best shape at the moment with a nice trigger, and cocking without missing, you know, when you have to pull the mag to prevent a double load? It hasn't been doing that any more.
I'm still having to hit the bolt with my palm to seat the pellets though, but it is getting easier.

Here's the target

The Excite group in the middle, and the Barracuda's lower left. They had some pretty good pop on those Co2 cartridges. Took a primer out of a shotgun hull, and all kinds of other amall targets.

Can you explain a little more about what this process does?

From the phrase “break in the chamber chamfer” I think you’re describing what is currently a sharp transition into the rifling...in other words it is blunt / not tapered. So is this break-in process expected to produce a chamfer, or pack in material in front of the lands to improvise as a taper?

Yes that is the goal, to blunt the the riflings edge.
I would be in the same boat as you, only hazarding a guess as to the actual process. It was sugested by someone I trust, as being somewhat of a long process. A barrowed pictuure of the problem, along with a a pic of an unshot pellet, after being loaded.

Thanks for the example photos. Ouch…that poor pellet!

I suppose it’s possible that material shearing off and packing in front of the lands may provide some relief to future pellets, but I am skeptical of it being permanent or consistent. A proper fix is surprisingly easy to accomplish with a rubberized abrasive bit spun up in a handheld drill.

If you decide to tackle it, let us know and either I or one of the other experienced guys here can get you going.

That is the next step.
I want to do the chamber, and check the crown. Once I have it appart I'll probably do some of Hajimoto's mods as well.
 
It is much more practical and economical to take the route nervoustrig is suggesting imo, even if you have to ship your barrel off to someone more capable, that should cost less than the pellets you toss down the barrel in attempt to create a 'ramp' for future pellets.

Plus you would have to concern yourself when cleaning the barrel to not undo your lead ramp.

Another vote for doing it the right way.

Did anyone solve a problem gun?
I've got a .25 cal Gauntlet 2 and I had the same issues your having. I've got a machine shop here at my home and I put the barrel in a lathe and put a chamfer on the leade of the chamber and I re-cut the crown on the lathe. You can chamfer the the leade with a Dremel using one of the soft pointed polishing bits and some metal polish with light pressure....just do it a little at a time and keep checking it. Is that pic you posted the crown on your barrel ??? If so, in my opinion that needs to be cut back to the rifling and re-crowned.
After I fixed the chamber leade and the crown, I also milled out the transfer port a little larger and polished it, then I installed the Hajimoto valve kit with the new poppet and hammer spring with the hammer adjuster, drilled the hole in the stock for the adjuster. I can honestly say that after doing those mods, my gauntlet shoots almost as well as my new MK 3....I shoot the .25 cal Hades in it at around 890 fps. and at 50 yards it will eat the bullseye out.

Thanks, and again this the direction I'm headed with this rifle. I'm just meesing around with it right now.
That picture You're asking about, is a picture of the breech of one that Hajimoto, sent me to show me what I was dealing with.
 
Update:
I haven't done a thing with this gauntlet2 except puchase some tools and various cutting pastes, however I did put some lead barracuda's in it, and low and behold, it shot well enough to hit shot shells, and CO2 cartrdges, at 28 yards.

I shot about another 500 rounds through it, and moved to 75 yards! Now its shooting about 3/4" groups, with about six in, and four fliers out. What an improvment. I am shooting bottle caps, shot shell, and CO2 cartridges, at 75 yards now, but it still sends those ocasional fliers.
My best shot was at a CO2 cart that was lined up with a string. I got them both. I even shot a CO2 cart logwize, about a dime sized target in four shots.
I still have to palm punch my bolt home, to seat the pellets.
 
Hi 20cal working on my Benjamin , still a bear to cock it but getting better, installed a rip cord on the bolt , easier to pull back .
I had a Gen 1 gauntlet also hard to cock , good luck
Hi beerthief
I've been thinking about you lately. I just ordered a front rest similar to yours. I wound up with the Caldwell BR. Its still in a Fedex truck somewhere, but looking forward to it

protector front rest bags fit i think, and you can buy in different gun stock width's if you need one
