Tuning When did you decide to start working on your springers?

The gas ram Cometa 400 is an awesome rifle that anyone can take apart with no compressor ot tools.

I have more trouble free shots with it than any air rifle I have owned. It's inexpensive, shoots 740 fps in .22 and is easy to shoot. It's not as nice as an HW but it is (almost) as accurate. The trigger is good. The shot cycle is quick. They last a long time. I've shot mine 20,000 times since October and it's still shooting great.

That's twice as many shots as both my HW's combined. And I've had each of them rebuilt twice!

I've had it apart several times and there is simply no wear on the internals. The design is super simple. The piston is a piece of steel tubing with a seal on one end and a gas ram sticking out the other. You can rebuild it on the kitchen table using an 8mm wrench and a 5mm punch.
It often goes so that simple = reliable.

Ask any design engineer.

Just curious, do gas rams ever need to be rebuilt or have seals replaced?

My springer journey has been an absolute Odyssey. Everyone here at the forum was instrumental in keeping me focused on the light at the end of the tunnel.

The D48 is still leaned up against my bedroom wall. With the William’s peep, it’s a real shooter. I’m still hesitant to put my thumb in it though.

Fashioned a pellet pusher out of a plastic pry bar. Dogs ate it! Ha
Yes indeed, the Diana 48 is an excellent gun. Good solid German steel. I too, added a Williams peep. I understand there are kits that somehow improve the spring and other stuff. If anyone has actually installed any of that I’d like to know more. Things to collect in case I ever decide to tinker.
I take it out a few times a year just to remind myself how well a good springer can shoot. I understand Diana no longer makes the 48? If true, not sure why they’d do that.

I have had my RX1 since 1993 and put I would estimate 30 to 40 thousand shots thru it. It still shoots fine, but don’t shoot it as much anymore. But I have heard of some needing new o-rings.

I must be really lucky with my HW’s. Literally no catastrophic problems. But these were bought in the early 90’s. Not sure if they are still the same quality. Hopefully they are.

In my limited experience yes.

The ram in the Cometa is not rebuildable as far as I know. It is shooting 620 fps after 20k shots in 4 months. I re-sealed it and it's still slow. So my assumption is the ram has lost some power.

I have heard a ram goes all at once or it's fine. I have my suspicions. I'm getting a replacement ram one of these days and I'll know for sure.

What I do know is the ram has a great shot cycle and dosent twist like a spring. It's quick and then it's dead. Straight back and forth. It's easy to hold and it's not "tricky" like a spring. It kicks. But it kicks straight back and forth.

I have several springers and I like them. The Cometa would be great with a spring. You can get them either way. You can convert them easily.

It's (IMHO) better with the gas ram. The ram is inexpensive (about $25 bucks if iI remember correctly) and has lasted longer than any spring I've shot by a lot. I REALLY like the shot cycle of the gas ram. And slapping in a new ram is a 10 minute job.

So I'm a believer. I like the gas ram and I like the rifle. Again IMHO it's the best value I've experienced in an air rifle. I'm glad I decided to try the gas ram rather than another coil spring rifle. And the accuracy has really impressed me. Both my Cometas will really stack them.

It’s a very easy gun to tune. This one has a pg4 kit, barrel tweaked to optical center, and carbon fiber barrel sleeve with moderator adapter. I sometimes run a Sumo on it.

If you hang out in the "what springer did you shoot today" thread, you will quickly learn that the right thing to do with a new springer is; #1 Take a few shots to establish a baseline and make sure your rifle is functional, #2 tear down said rifle to it's component parts, clean the crappy grease/lubrication that the manufacturer uses to keep rust at bay, #3, at the minimum, relube with moly or even better krytox, #4 add a kit from Vortex, Maccari, TbT, or ARH (sorry if I can't recall the others), #5 marvel at how much smoother the shot cycle is ('tis true). #6, manufacture your own components with precise machining and extreme patience. I hope #6 is optional, but more prevalent than expected ;-).

So I now have 8 springers (newbie) and 7 have been treated as above. In the past month! The 8th is a gas ram. I was intimidated at first, but youtube videos are extremely helpful and the rifles really are quite simple. Nick's videos (TbT) are my go to...Cheers!

RC, you’re a bad influence … thank you! 😁
Now I’m gonna have to dig into my beloved 48

I shoot my under levers a lot and as a highly skilled member here once stated they are either “coming together or coming apart”. Shipping a gun across the country for some simple repair seemed needlessly expensive and worrisome so I made a spring compressor and started doing my own wrenching. I just wish there was a source for inexpensive oversized spring guides and top hats. These can be brought down to size on a drill press. I don’t have a lathe and don’t expect to ever own one. Uj

Never say never. I never thought I’d have a lathe, and then one day I visited a local machine tool auction out of curiosity and picked one up for a song

Add me to the list of those who love your YouTube channel. I started shooting spring-powered rifles when I bought my FWB 124D from Robert Law at ARH in 1979. #18866, and I still own and shoot it. It is on its second rebuild, the last by Motorhead of Northern California. He is a fine tuner and has rebuilt nine of my springers.

I bought a twelve year old Diana that was new in the box. Without even giving it a thought followed the above instructions to the letter. But I also did what ever I could with the trigger. It is just kinda how it works.
