Macarri...

[JTK]

Hi guys,

I emailed Macarri to find out if they have a replacement spring for my Stutzen. The suggestion back from them was the R9 Tarantula. The site however suggests that the R9 is not for Gamos: "Not for Gamo's. We do not offer springs for them as they are often used but not a practical Gamo spring." Is this only because you have to make a guide that fits the spring? or are there other reasons? I decided I will rather get a Macarri as a Gamo replacement here will probably set me back the same $$. This gives me the excuse to get some moly, tar and a seal as well

[Stutzen]

According to experiences of a friend of mine, here in Ankara-Turkey, it is correct. He had bought and mounted a Tarantula spring to his CF-X.
I remember him telling that he had to make some inner changes/replacements for fitting Tarantula. But the result was perfect ! I used that gun.
If you need further help, I may give him a call; and I am sure that experts here will write more explanatory words about Tarantula.
Regards.

thanks Stutzen please ask what he needed to change.. I assume you have a Stutzen judging by you alias. What, if I may ask, have you got in yours? still stock?

thanks,
JT

Hi,

Considered emailing Jim back pointing out the inconsistency between the statement on the website and his email? I'm sure he too has an explanation. Though if a spring fits, it fits. It might not be meant for it, but as long as it's not too powerful for the action, who cares?

Considered a gas strut?

I think a lot of his springs have many other applications other than what they were intended for . Adapting may require spacing or a new guide , or maybe a new seal, but can be made to work in several guns. kirby

There are a couple of springs that will work in the Gamo but Jim does not make a spring that is a true Gamo drop-in replacement spring .

The closest that he makes is the E-1500 I believe. I also use that, the E-2000 and the Tarantula depending on what I want to accomplish on what gun. The E-1500 shoots just a bit softer than the stock spring and a bit tighter but as with any full tune, should have a fitted spring guide and tophat.

When using the E-2000 you should take the necessary measurements to calculate and compensate for the coil bind factors and for making the necessary changes  in the tophat height and spring block heights. If not done correctly, the gun will not cock.

 The Tarantula is a good spring to use if you make a full fitted guide and tophat for it. If not, then don't use it as it will fit looser than the original factory spring.

I think that it's important to point out that just because a spring "fits into the gun", it certainly doesn't mean that it "fits the gun". You may....(or may not)... be able to cock the gun and it will probably shoot but what good is it if the performance or consistency isn't there or the possibility of causing other damage? There are many factors that come into play regarding a guns performance and it's relationship to the spring. For a few, the wire diameter, coil count, preset, spacing, coil bind, inside diameter, outside diameter and the spring wire composition.

Thanks for the replies. I did mail Macarri back and the response was pretty much as stated here.. The spring will fit but needs tweaking. As I am fully prepared to turn a tophat and guide it does not realy bug me. He told me: "No that's because its a bit loose on the guide and Gamo people often never replace seals and sadly do bad things on the cheaper models like make them diesel. Also shoot junk pellets and the guns have no barrel choke- That said its wise for me to avoid the novice. That aside selling to older competent owners with common sense is OK."
I thank him for his response and will take it that I need to fit the spring but the power will be compatable for my Stutzen.  

Bob, would You suggest I go for another spring from Macarri or should I stick with the R9 Tarantula for my Stutzen?

Thanks!

[JTK]

yes..  but the spring will set me back like $20 odd with shipping and a gas strut, if I can find one, maybe 10 times that  

[CharlieDaTuna]

The Tarantula will work just fine if you make a new guide and tophat for it. A lot of people used the Tarantula in the past in the Gamo and weren't really satisfied but it was because it wasn't set up properly and most people aren't equipped to do what is really required.

Some people, after using the Tarantula spring for awhile experienced canted springs, cracked or broken spring blocks or excessive vibration when the lubes flew off the spring and had some complained that the springs were bad. It wasn't the spring at all. It was poor workmanship or lack of knowledge by the person installing it. That's why Jim tells people that he doesn't recommend for the Gamo and I don't either unless a person is pretty knowledgeable and can do what it takes. I have used them for years and have never had a problem but then I machine everything to fit the spring. Personally, I think the Tarantula is a great spring. In my opinion, there is nobody out there that make a better spring (or lubes) than Jim and his springs (and lubes) are all that I use with the exception of something he may not stock.

As always, thanks Bob! I realy appreaciate the info. Will order one and turn tophat from stainless and guide from delrin.

[Stutzen]

I always admired (and still do) Gamo Stutzen. But I have a RWS 46 stutzen with V-Mach kit installed. The only pellet that I could measure was TS-18 and it was making 600 ft/sec with that. I recently requested a chronograph from my USA citizen buddy Dennis and when it arrives I will check for other brand pellets.
As for Tarantula, I will call my friend if still rewuired. But let me tell you that he installed it in CF-X, not in a stutzen.

It's kinda like taking a stock motor and putting 12-1 pistons in it without changing anything else, I would think other things are sure to fail.

Bob, how many coil tarantula should have for CFX? I can make the guide and tophat. But not sure how tightly the tophat should fit with the spring. Will that be so tight that tophat cannot revolve inside the spring or tight enough to allow the tophat or guide move freely?
