tuning questions

[familydc]

I just sent my gamo whisper .22 in for a tune.  I am new here and never had a tuned air rifle.  I have just a couple questions that I am sure you all can help with.  

1.  With the tune and new spring will there again be another "break in" period for the gun?  I felt it took a good 250 pellets to get better grouping when I initially purchased the gun.

2.  After trying a number of different pellets I felt crossman premieres gave the best grouping in this gun.  Will this possibly change after the tune or is the "right" pellet more a function of the barrell only?

3. I assume the new macarri (sp?) spring is the same size as the stock spring as fps is supposedly about the same after the tune as before.  What makes it better than the stock spring?

4. I really don't care because I am having a lot of fun with the new hobby here but tell me the truth.  Is it rather dumb to spend $200 on a tune when the gun only cost $200 to begin with?  Should I have just jumped in with a $400+ dollar air rifle?

Only answer I can give is it really doesn't matter the price of the rifle... EVERY rifle will benefit from a good tune... though the better the rifle most probably the better the end results will be.....

Yes there will be a break in period to seat the new piston seal and get everything cozy inside. The Maccari spring's and piston seals are of a higher standard then the stock Gamo seals and springs and will perform great. FPS can be different for the same brand airgun even after a tune compression tube variations etc. can be different from airgun to airgun. A tune will give you a more consistent FPS average along with a smoother cocking and shooting airgun which is a major plus when target shooting or hunting. The break in period can differ from shooter to shooter after a tune some can take less then a tin and others several tin's to to get em going. The main thing is to re season the barrel after a tune since the barrel is cleaned during a tune. Get the lead in there to fill any imperfections and increase accuracy but I have done a tune on several of my airguns and had them back on target with less then a half a tin. Having a good barrel from the get go is a major plus in the re seasoning process. The Trail NP that I received from Gene while I was down at his tuning shop in S.C. was still fresh from a tune when I was dropping nutters down there and up here it's already added a Bandit and Country Rat to her kill list and I still haven't put two tin's through her. I just finished up a ShadowSport that was pushing CPHP at 830fps before the tune and after it's sitting at 890fps plenty of power to hunt small game with. It's not about high fps but consistent fps but still in the happy zone for hunting etc..Ed

Oh and a change of pellet type might come into play after a tune but CPHP's seem to like many shooter's before and after and yours may still be happy with them. Another pellet that's been successful is the Beeman FTS my NP didn't like the CPHP's but loves the FTS. Ed

That thing will be a different gun when you get it back. The tune makes alot of difference. I especially noticed it in my big cat. It used to be pretty accurate before but after the tune it's just not comparable to a stock gun. You will be happy for sure. And you can't put a smile on happiness. You can't take money to the grave either, may as well spend it on things that make you happy.

There is always a break in after a tune it will settle down fairly quickly and then you will need to test pellets to find the best chioce. CPhp, CP dome , Beeman FTS , rws dome and Meisterkugeln would be a good start IMO. I have tuned 200dollar guns an tuned 600dollar all very well worht the cost:)  Tony.

It doesn't matter.  If you bought a $400 rifle initially, you're going to want to spend more money on a good tune anyway.  That's just the way it works.  Best not to fight it.
