GRT-III trigger how much difference?

[roadrnnr42]

I am new to the forum and to spingers. In Texas when you file for divorce you cannot be in possession of a firearm. My attorney said an air rifle cannot be classified as a firearm. My son and I both like to hunt and to plink with .22s. and not being able to posses a firearm through the season was going to be a bummer so I thought about a pellet gun. Went to Academy Sports to by a Benjamin just to plink with and to my surprise they have a Gamo Shadow and Varmint Hunter that boast 1000 FPS velocity. They look pretty cool too. I know if I show up at the deer lease with this thing I will be laughed off the place and probably not allowed back on until next year but I enjoy the lease, cooking out and how relaxing it is there so I chance it. We get there late Friday night, cook, play cards and go to bed. The next morning everyone is loading up the 4 wheelers to head out to their stands and I take out my Varmint Hunter, load up and head out. No one even notices it is a pellet gun.
No, I didn't think I can kill a deer with it. My thinking was I could sit in the stand, listen to my ipod, and maybe shoot a few quail coming in to the feeder, a rabbit or squirrel, maybe an unsuspecting armadillo, skunk or something. Just being out with a gun in my hands, even if it was pellet gun, was better than the alternative. I should mention that before going to the lease I had put about 1000 rounds through it, a new 4 x 12 x 40 scope on it, and had it sighted in at 30 yds. At this point I hadn't tried any shots beyond 30 yds and wasn't sure what it would do, how much drop it would have etc.
It starts to get light out and I see a sparrow in a tree. I take out the range finder and see that the range is 48 yds. so I raise the elevation 6 clicks thinking to compensate for the drop. I sight in and fire. Miss. Can't tell if it was high or not, but I decide it was still low so I aim again, this time about 1" above the bird. Missed again. This time I aim at the branch the bird is sitting on and the bird ducks his head when I fire. Okay, It is shooting high. I bring the elevation down 6 clicks and aim right on him and he drops like a rock. I am surprised at the flatness of the trajectory and decide to see what this thing will do at further range. I had bought some crow magnums but hadn't had a chance to shoot them. Knowing they are a heavier pellet than premier hollow points I was shooting I load one up, give the elevation 12 clicks up, and fire at a rock 50yds out. Hit a little in front of it. I play with it for a few shots and have it hitting a rock at 60yds within a few shots. This is starting to be fun. Much more concentration and skill is needed to shoot this thing than I ever had to have with my .243, .223, .22 or .270.  
To make a long story short, I get back to camp, one of my buddies sons sees my Gamo, and ask what I am doing with a pellet rifle. Man did I catch some crap. My buddies son, Nick,  ask if he can shoot it. I say sure, it is sighted in at 50 yds, and I catch more crap. When they quit laughing Nick takes a beer can and starts walking out to set it down. He stops at 20 yds and I say to keep going. At about 50 yds I say that's far enough. ( more laughing) He sets it down, comes back, picks up the Gamo, loads it, and starts to sight in on the can. (more laughing)
Bless his heart he hit the can. ( Silence) He fires a few more times and maybe hit it again 2 out 5 times, but he was close on the ones he missed and the misses kicked up dirt off the hard ground and you could hear the pellet ricochet off into the air. Before the evening was over, everyone had shot it, talked about how powerful it was for a pellet gun, and had used up my can of crow magnums.
My question is this. How much more accuracy do you get with the GRT-III Trigger. I am hooked on springers and want to make this as accurate as possible. I know I have missed shots do to the pull required on the stock trigger.

If you go to product reviews at the top left of this home page. Look at the review they did on the Gamo Whisper. They took shots before trigger and tune. Then again after, and there is a big difference. As soon as I get a couple cans of pellets through my gun it will get the trigger and tune. These springers are way too much fun.

Shot straight,

Welcome to the GTA Forums Mike,

And the easiest way to answer your question is to say, The GTA-III is GREAT !!!

The difference between the Gamo trigger and the GRT-III, is Day and Night.

It is like installing a match trigger into your Gamo, and I do urge caution when you first install it, make certain that your sights are on the target before you touch the trigger, cause you will not believe the difference it makes.

The GRT-III is the best money I have ever spent, on anything !!! And I have spent a bunch of money on wonder products, that just do not live up to there advertisements. The GRT-III is better than you can imagine !

I hope this helps !

It helps. I too have spent money on wonder products with great reviews only to be sold something that was inferior or a piece of junk. I started checking out air gun sites a few weeks ago and kept hearing about the trigger. finally someone mentioned Charlie DaTuna and I looked him up on the web. THink I will go ahead and place my order. Thanks,

Your probably getting used to the stock gamo trigger, so it seems like its an ok trigger to you.  But once you put in a grt, you will never want to go back.  It takes your mind off keeping the crosshairs on target while pulling the trigger, and you can concentrate on your overall shooting technique instead.  It's a must have mod.

remove the trigger pull adjustment screw and replace it with one that is about double the lenth. Turn it in until the rifle does not cock. then turn it out about 1/4 to 1/3 turn. Now you will have a trigger with almost no creep. the weight will still be there but it is already 100 times better than stock at this point. then you can also remove your trigger and polish the areas high ligthed below. Make sure you are carfull not to bevel the edges. just keep the sides straight. You need to do this to get 100% benifit from the grt3 anyways. this will make the break smooth as glass and not "grating". pics of replacement srew and polish areas.

Mike,

Welcome to GTA! I had similar doubts about the "wonder trigger" Bob sells. I kept reading all the testimonials from satisfied users and finally worked up enough courage to purchase one. Not for one instant have I regretted it as the GRT-III, in my opinion, is the single best modification you can make to a springer like your Gamo. After the installation in my S1K, I scraped up enough cash to convert my Hunter 440 and my son's CFX with GRT-III's as well. Bill's advice is sound, as you darn sure want to have the muzzle pointed in a safe direction when you touch the new blade for the first time.

Good luck with the new rifle and I hope some of your hunting buddies join in on the airgun fun. Tell them that Natchez Shooter's Supply has the Hunter 440 (basically, the same gun as yours with a nice wood stock) for only $99.99. That should net you a few local airgunning pals.

roadrnner42, best $32 you will ever spend, made my CFX a shooter any Marine would be proud of.  It hits what you point it at each and every time without holding effort,  CDT sez, "ergonomics" ; that is the secret of the GRT-III.

[brokenarrowjbe]

get two, in case you buy another air rifle, you will all ready have it. John

[davee1]

I'll second that...I have two, one in a CFX .22 and one in a .177 shadow.

It was the best mod I've ever performed, and best bang for my bucks ever. Firing that trigger is like having it on silk...smooth, very lite, and improves accuracy becuase there is no jerk from pulling the trigger because it has such a fantastic lite pull effort. And like somebody mentioned before, its better if you get used to a Gamo trigger first and then do the mod, that lets you appreciate it 100%. Once you feel the smooth pull of the GRT-III...you'll probably want to put it on any other Gamos you might have or get in the future.

I've never heard of anybody who didnt like them. It is amazing what this little trigger does.

I wish Charlie had one for the Hammerli Storm .22 I have, that would make my Storm my favorite hunter. Thats ma skunk rifle.....and I pray every nite for Charlie that he might find the time to do one for the Storm.....

From the above statement:

"you can also remove your trigger and polish the areas high ligthed below. Make sure you are carfull not to bevel the edges. just keep the sides straight. You need to do this to get 100% benifit from the grt3 anyways. this will make the break smooth as glass and not "grating".  

The Gamo trigger does not really need to be honed at all when using the GRT-III and I strongly urge you not to do it. There is only about 6 ounces or slightly more difference from the point of seer contact and seer release when using the GRT-III  in most Gamo guns anyhow. Over time it will wear in gradually on it's own as the surfaces are mated. That's why you hear people say the their triggers improved with shooting. To do the above, you do so at your own risk and I suggest if you do, do so with extreme caution . If I would know in advance that someone were going to do it, I would not sell them a trigger. Just let it seat and wear in on it's own. If anything, just burnish the surfaces with moly paste.

 I would be very careful about doing both the screw as well as the seer finishing on the sear and intermediate lever. The screw needs to be backed out enough (at least 1 1/2 turns to be positively safe)  and that it will not go off accidentally which can happen if bumped hard or even slightly at times. Very very dangerous if balked fired. It is very easy to happen if either of the sear levers wear some and you will never even know it. The sear and intermediate lever if honed beyond a certain point can be extremely dangerous. This is especially true in any Gamo clone trigger (Chinese). Either will discharge all by itself or will not stay cocked. Once it reaches that stage, the trigger is junk and the parts need to be replaced which you cannot buy.

 Many wood stocks and a few synthetic stocks have been broken because of it as well as a number of people hurt over the years. In fact it has happened to me because a customer didn't tell me that he had worked on his trigger before he sent it to me without telling me of the condition. I was so upset that I sent his gun back and wanted no part of it.

All said, unless you know precisely what you are doing and how to do it, and the limitations, and have the right tools, be extremely careful so you don't hurt yourself or someone else both at the time or later as time goes by.
