It has been awhile now since I first posted this so I will no longer be taking any further comments or questions regarding the matter.
I thank you all. Happy airgunning!

Well after what seems like forever I finally have my phantom air rifle tuned. It was a long wait as I had originally gave it to an experienced tuner ( who I will leave nameless ) to be tuned. His schedule was a busy one and after 2 weeks he had not yet tackled the job. This was fine by me as I really wanted my rifle to shoot better than it was. However during this time I started hearing unfavourable reports of the said tuner's workmanship and trustworthyness. Not having experienced anything negative with the fellow I was fine at first. ( I like to give everyone the benefit of the doubt ) But as the days went by and I heard more and more bad stuff about this guy I started to get worried. So after contacting him I was able to get my rifle back untouched. I choose not to mention the tuner because my experience with him was not necessarily a bad one. Who knows he may have done a good job on my gun or he may have not. In the end it all worked out well as I gained a learning experience as a result.
Now onto the air rifle. After purchasing the rifle I was fairly pleased with the way it shot. I found it to be accurate and though at first was not too fond of its appearance grew to appreciate it's form. I find it very ergonomically fit and easy to shoulder and hold. The one thing that disappointed me however was it's lack luster power.
My main reason for buying this air rifle was to control the squirrel population in my yard. They had done damage to my wife's bird feeders but more importantly found their way into our attic. That was enough for me. I had heard how hard hitting this gun was out of the box and so on so I decided to get one specifically to rid the pests. Even the box indicates that the gun is suitable for pest control. My first victim unfortunately didnt go down easy. A 20 foot shot to the neck only had him bleeding all over the snowy lawn. At one point he got back up sat there and watched the blood coming from his neck. To my amazement he started to walk back to the feeders ?! Thankfully I took him out with a second shot to the side of the head. It was over but I was not happy with having him struggle after the first shot. This scenario was prior to me chronying the air rifle.
Prior to the tune I chronied the phantom using 3 different pellets. Here are the results.
BEFORE THE TUNE UP
Crosman Hollow Points
Avg. fps 417.66
Avg. fps 429.7
Avg. fps 469.78
After the lube tune and piston change that I performed here are the after tune results.
AFTER THE TUNE UP
Crosman Hollow Point
Avg. fps 712.47
Avg. fps 700.15
Avg. fps 738.3
After seeing these dramatic results I can tell you that I am now satisfied with my air rifle. I know I could change the spring and do a few more things to really let her fly but Im happy with it's current configuration. By doing the lube tune and piston change I realized a big increase in fps of 268.52 with the Beeman lasers and a whopping 294.81 avg fps increase with the Crosman Hollowpoints!
I mounted my centerpoint scope on it late last night and surprisingly shot this at 27' . Since it was late and that first shot was bang on and the fact that it shot thru my pellet box I decided to call it a night.

I’d like to start by stating that this was my first attempt at tuning an air rifle. I used a combination of guides found online from various sources including Charlie da tuna and information from several air gun discussion groups. I decided to make a guide specifically for the Crosman Phantom 500 .22 cal air rifle since there were none to be found at this time.
That said if you take it slow and work methodically you should be able to achieve successful results.
Now onto the tear down.
1: Remove the 2 forward stock screws and washers.
2: Remove the 1 screw behind the trigger.
3: Remove the receiver from the stock.
4: Break the barrel free but do not cock it! Remove the barrel block pivot bolt to separate it from the receiver forks.
6: Next you have to unhook the sliding block spring from the trigger block. Unhook it at the front leaving it hooked at the back on the trigger block. You can now remove the e clip as well.
Then punch out the lock pin with a wooden dowel or a screw driver and a mallet. Once the pin is out while still retaining pressure on the receiver, pull out the dowel or screwdriver now in the hole. Slowly back off the pressure as the spring pushes out the end cap. Voila!
Similarly when putting it all back together you can try to do it the same way without a compressor just in reverse order. However putting it back is a little more difficult as you have to line it up right and put the lock pin back in. If you decide to put in a new stronger spring it will prove even more difficult without a compressor. It is your choice how you proceed.
9:Now you can remove the rear spring guide followed by the spring.
11:Take the tophat off then pull the piston out using a screwdriver thru the slot of the receiver. My tophat did not fall out on its own. Seems there was some corrosion keeping it stuck in the piston. I sanded her down smooth before reassembly. (the above diagram is taken from a web source)
