Hi all, anybody have any experience with the .22 pellets. My sheridan 5mm is wore out. We have a major a$$ pest problem where I work, and so, I was considering retiring my 5mm, for something harder hitting. O.
How old is your 'Dan? Especially if it's an old one, don't give up on it. There are a lot more .20 pellets around for it and they moslty weigh the same as the .22s with less frontal area.
You can send it to Mac-1 for a "Steroid Tune as well as reseal and maybe a Billet lever for chump change compared to a new gun.
"Mac-1 has modified Sheridans for around 2 decades.
My approach changes as the guns evolve. I could at one point many years back simply install an adjustable piston, a better check valve, and a beefier hammer spring and we could coax 900 out of most 5mm's. Things have changed a great deal. To get that type of performance nowadays from an early dan as I call Sheridans you would need to machine the valve, remanufacture the lever or replace with billet, fabricate custom inlet and outlet seals as well as do the custom piston. It actually is a little easier to start with the new gun and go billet/steroid/williams straight away and You don't have to fuss with whether the gun can take the stress etc. But it isn't cheap and if you have an old C laying around with a blown check or leaky valve you just might have a gem in the rough.
Early model C and CB.
The basic tune is $55 which uses upgraded factory components and Mac-1's check valve. What gets done on a $75 steroid tune?
For the additional $20 I remachine the valve body to receive Mac-1's delrin outlet valve, install a custom adjustable piston, beef up the factory lever, and tune the gun to around 900 fps.
What's a billet lever?
$45
The factory discontinued the levers for the C and CB several years ago. I tooled up to remanufacture the factory lever with new pivot bearing. When buckled levers came in we could not fix the guns. We were forced to do a billet lever cause we were completely out of levers. Billet anything is defined as made from solid stock. In this case the lever arm is machined from solid steel and the part is far more rigid than the stock item. Made with a replaceable hardened steel bushing at the primary pivot this lever is what I call the lastlever because it will literally last forever. Billet levers are available for new and old model guns but when fitting the billet to any C or CB the customer is advised to also replace the early front plug with a late model brass plug($5) to make sure the front end is solid and the pins don't slip out. So the total to do a billet steroid to an early Sheridan is $125. These will shoot over 900 in .20 with light ammo at 14 pumps.
Late Model C9A or CB9A or 392.
Steroid Tune $75 on your gun. Adds $45 to the price of a new gun. The late model gun gets a little different treatment. I do the custom piston, delrin stem, and beef the factory lever. I also do a bolt probe modification to enhance airflow and of course the two stage trigger is tuned to a 1 lb. take up and 2-3 lb. break. The billet lever(adds $45) is especially popular with the new guns. It makes the lever feel like a quality car door shutting. So a billet/steroid tune including trigger, piston, bolt, and valve work cost $115 for YOUR late model gun. It costs $90 on top of the price of a new gun purchase." Look at the pictures at the first link on the right side to see what the extended billet looks like compared to the stock gun).

http://www.mac1airgun.com/services.htm A Steroid Sheridan shooting 14.3 Crosman Premiers @ around 900fps (you'll want the Billet lever option because it puts a lot more stress when pumping but you can go with the extended billet lever option which cuts off some of the stock and uses a longer lever for more mechanical advantage when pumpiing and looks pretty good too) will be putting out 25 Ft-LBs Energy. You'd need to spend over $500 buccks for a PCP gun plus a scuba tank or pump to feed it, or over $1,00 to get a springer that would do that(and then have to learn how to shoot it............and you already know how to shoot the Sheridan from wearing it out the first time)!!
So, for $115 to $125 yiou get a Steroid Billet tune or for additional few $s(couldn't find the price but I think it's another $35 or a total of $145 to $155 depending on model, you can get the Extended Billet as well. If you don't have the Wiliams peep, that's a $25 option.
