I have a PDI hopup chamber, 6.01 raven barrel, and PDI hard barrel spacers. I use a spring that shoots a .2 bb at roughly 430, and .36 bbs. What kind of grouping should I be expecting, and at what range?

This answer is relative of course, but IMHO at least a soda can consistently (~8-10 out of 10 shots) from 100ft.

A soda can from 150ft is great.

200ft and you're in business >.

hmmmm I seem to be lacking then.

If you are going to perform tests to improve your platform, remember to work in a "sterile" environment in terms of how many variables are going to affect your data gathering.

You might end up in a terrible pit of uncertainty which is - in fact - how the world goes..but tests-wise you must try and be the most scientific possible. Most think that this is overkill for a hobby like airsoft, but even if your mind is not obsessed with doing things at a class-A level, you should remember that failing at conducting a nice test patter might hurt your wallet (e.g. buy lots of stuff you don't need or that does not work as expected, by trial and error) and therefore your future gaming experience

Remember to follow the golden rules of testing

Just to make things simpler, I think you should be able to hit a human chest sized target at whatever distance you want your gun to shoot.

For practical testing, I recommend getting an object, like a small box, which is roughly the same size as a human torso. Place that object the same distance you want your rifle to be "effective". If you can consistently hit that target, then congratulations :shot:.

A 100ft soda can test is a standard for my guns though Even my 3-inch barrel guns >.

Pfft, my standard is a pea at 100 meters.

Just kidding. I would not be satisfied with anything less than torso-capable at 80m though. In all honesty, I expect every single one of my rifles to be fully effective at 100m or more.

You mean sniper rifles, right?

..and this kind of performance is going to be a pain to reach if you - allow me to restate that - do not follow some solid method and consistent environment testing. Cheese Man is one of the living proofs (see what he does in terms of gun teching..you'll understand he indirectly taught me a lot since I came here).

'nuff a** licking now, chaps

There was a thread in the gallery category about some of cheese's guns. When he says "every single one" of his rifles, I think he means it.

 

[Cheese Man]

I meant every single one.

It's really not too bad though, honestly. I only spend an average of about 60 hours on each gun getting it there. WAAAY better than when I started, my average was over 100 hours :O

 

[Masterjuggler98]

Just to clarify what cheese said for all who think he might be insane; if you spend a few hours a day for a while, it can add up to a lot of hours. Just don't want all the "holy cow how much time?!?" posts that would be sure to follow. :tup:

 

[king..kranium]

Maybe cheese can give is a guide as to how to come close to his gold standard.

Nope, I actually spend about 12 hours each shift. I use about 5 days, 12 hours/day to tune these things.

Thanks for trying tho.

I would, but I do also have a business to run. My tip to you is to use the interwebs, do some research, and don't be afraid to break things. Airsoft guns are actually pretty resilient, especially spring rifles. You can inflict some serious torture and they will still work just fine with a new part or two.

 

[Masterjuggler98]

Alright cheese, you've proved me wrong, you are a little insane (; And I am a little afraid to break things because it's not so easy for me to order new parts. My parents like to control my life. They will also be all "told you so" because they won't understand what I was doing and will let me order new parts even less. Rant over.

 

[Cheese Man]

It isn't for me either... Like I said, things don't break very easily, and especially to the point where they aren't salvageable.

 

[king..kranium]

Damn trade secrets lol. Do ya thing cheesy.
