Does anyone have a walk through on how to tune my New air rifle to bring it up to the specified 495 FPS or at least close to it. I have researched everywhere and cannot find a detailed description on how to do it. I am new to tuning and modding air rifles but have owned many. I really would like to learn for anyone willing to teach me !!!! From my research I have deduced they shoot around 420-440 FPS out of the box.

Mine shoots Hobbies (11.9g) at about 477 fps, so you might want to chrony it before you do any type of mod...
A basic clean and lube wouldn't hurt, but may not be necessary.

every gun likes a different pellet,
that said, a good way to find out if the quality of the pellet you are using will give you the most FPS is to line up 5-6 of them on a table and take a close up high quality pic of them, than put them on your laptop and blow it up to compare, you can tape pics from side, top and bottom. (helps if your table is glass) or just tip them over.

if you reach in the tin/can and pull out 10 and find at least 1 with any kind of deformity that tin isnt for you jack.

i noticed a big difference in grouping and 'power' in the different pellets, so far my gun is happy with RWS

you can also clean the barrel, use a string pull through if you can, if not a metal rod will do the trick but careful not to scratch the barrel. you can also put a bit of lube on your seals.


if you do all that and your still not getting the best FPS switch to a lighter pellet or take the gun apart for better inspection

From what I see you fill the bleed hole with JB weld and drill new sized holes on it till you get the velocity you want. You'll need one of those tiny drill bit kits, not the ones from hardware store.

that sucks that you cant get your hands on anything else.
what about shopping online? is that an option?
i just got a bunch of stuff from D&L, called the girl on the phone and she was very helpful, had my stuff here in 3 days.
they do have sample packs also if you dont know what is best for you.

I wouldnt know where to order from nor which pellots work best in my gun as else where on this forum I read you can go too light which causes damage to the piston. I want to do small pesting but all i have is crossman pointed and crosspoint hollowpoints. Idk what would work best for such an what my gun will be happiest with

as for what works best, there is no golden answer, you just have to try a few different type and see which one your gun likes best.
you can TRY and do some homework as to what others have used on the same gun but thats a hit and miss deal. but at least it will put you in the right direction.

i personally havent had much luck with hallow points, i have tried them on a few different guns and not happy with either, on the other hand, my buddy uses them on all his bird hunts and he loves them. just goes to say the prev point.

now as to where to get pellets i just got an order from D&L (http://www.dlairgun.com) and im happy with them. you can also try ScopesAndAmmo.com and airgunsource.com they are good people and wont rob you when sending you something small.

they all have 'sample' packs of different brands, right now i'm using RWS and i'm happy with them, i have also heard great things about gammo, abit on the pricy side for my wallet but they have been known to be good.

bottom line, if you cant get this stuff from a store, you might have to go online
good luck
