Air Gun Home :: View topic - My Crosman Custom will be here next tuesday!

Jaxom · Senior Member

I hadn't checked in a few days, but there it was, when I checked my order status this afternoon, I've got the UPS tracking number!!! WooHoo!

Now, I've a few more questions...

"Out of the box", without doing any more to it other then the custom parts installed, and using a standard Co2 cyclinders, will this be able to take squirrels and pigeons? I really hope so, this way I can start putting some meat on the table, while I save pennies to get the DI jection and other parts required to go bulk on this air gun.

Next has to do with bulking. Those 20oz paintball Co2 tanks and air tanks are threaded the same, I won't have to do any other mods to the gun to go dual fuel? When it comes to upgrading to HPA, I don't think I've seen those tanks around locally, I'll have to order those online someplace. That only rifles I know for sure that use tanks are the condor/talon or the Logan S16. I would be ordering one of these tanks and installing that or are there other HPA tanks availbe that I can use?

Thanks,

Jax

AFAIK, if you go to HPA you also need a regulator.... Shocked

Explain please...

CO2 is about 850 psi.... Compressed Air bottles are very often 3000 psi.... Hooking one up directly to a CO2 gun would likely turn it into a pipe bomb....

There are many regulators on the market to reduce that 3000 psi down to safe pressures for CO2 based guns.... How much pressure a 22XX Crosman can stand I have no idea, but I'm sure there are others around who do know.... If you are looking for a source of good quality tanks and regulators try this site:

I agree with RS. JDS airman will have everything you need to go HPA. It would likely be cheaper to go HPA right off the bat and get a pump.

A 13ci 3000psi tank regulated to 850psi hooked up and used as your foregrip with a remote line. This in the end will cost you less than going bulk first. JDS and B&A should have all the parts and fittings you need to HPA the gun out of the box. I'd guess it would cost you $200 to go HPA and another $300 for a pump.

Well, for the most part, I'll be using Joe's DI replacement gas tube/valve and bulk conversion kit for my 2300. My main concerns were if the threads on paint ball tanks and hpa/pcp tanks are the same. This way I make sure I order all the parts at once.

Keep in mind though, I'm doing this in stages. First stage is to get the custom job in, and converted to bulk Co2.

Second stage is to personalize the air gun for my needs. This means installing a quality scope, camo paint job, installing bipod.

Third stage, bring up to hpa usage. This I hope to have done before next fall so I can hunt with it in cooler tempuratures.

Just was reading about how ambient temuratures affect pressures inside an airgun in another post.

I should note before I go any further. I have no intentions of keeping the stock valve in the 2300. It's my plans to buy both B&A's hi flow Boss valve and Joe's DI hiflow valve. Both are quality products. But I want to Chrono them in one gun. If either one shows even the slightest bit more advantage over the other, that one will be set aside and installed in another project I hope to eventually begin working on later this year.

While I am not planing on converting to HPA until later this year, it does help to understand how this is all going to come together for me. This way I can avoid making any mistakes, or worse yet, install the wrong parts and end up with a Co2/Hpa powered gernade in my hands.

I noticed over at the JDS air page they sell tanks with regulators that go all the way up to 2000psi flow rating. At first glance this may sound great. I can really put the smack down on a target or reach out really far. But do I really need that much power on say squirrels or rabbits at a closer range? Although I just may need that on hardier game, even if close. Racoons would be a good example of an animal that would need the extra fpe to put down at closer ranges.

Ideally a power adjuster could be used in this situation. However, to the best of my knowledge the only power adjuster made for the 22xx/2300 installs where the tank regulartor/mount I will be using will attach my 2300.

I can also see the advantage of a lower psi regulator from a "shots per tank" stand point. If I'm just back yard hunting or taking out an invading army of cans... Wouldn't need 2000psi to do that. Why waste the power? Just means I'll have to refill sooner.

Ah, I just went to grab another cup of coffee and some toast, while waiting for the toast to pop up, I was thinking about this delema. Then I thought, if I can't install a power adjuster where the tank regulator attaches to the gun, where else could one be installed. Then I'm thinking, what about somehow installing it into the gas tube cap??? The Co2/HPA has to pass through it anyways, this would be an ideal place to have an adjuster! hhmmmm

So, what pressure tank would you use in my situation???

I have no idea what pressure a 22XX tube is good for.... but since CO2 can reach 1200 psi in extreme conditions without blowing one up, and since JDS is in the business of selling regulators for HPA conversions, I would ask them.... I would guess that 1200 psi is OK, and maybe 1400 (they sell regulators all the way from 1200 to 2000)....

The Discovery uses 2000 psi, but it has a special main tube, and the valve has double O-ring seals, and is retained in the tube by three 8-32 (?) screws instead of the one 6-40 screw in the 22XX valve.... From my understanding, even a CO2 bulk set-up requires proper mounting of the valve in the tube, unless you are using an adapter that seals against the end of the original valve.... such as a cartridge adapter or a full-length adapter inside the tube.... both of which are designed for a remote tank, with no pressure on the 22XX main tube....

To get the most out of it, you're going to need a good adjuster to fine-tune the spring. If you get to much gas, it's not going to help a lot.

Storck-42 · Member

Yeah, one er these doodads..

Jaxom · Senior Member

I apperciate the concern Storck, but I've already taken care of which parts I'm going to use. Only two issues to solve now, is getting the cash to pay for them, and figuring out the bits requires to fill my tanks.

FWI...That adjust won't work with my application. The bulk kit I intend on using mounts the tank where any type of adjuster would go.
