Hey guys,

Waiting for my first airgun pcp to show up and I'm full of questions. 

First Question....AoA has new carbon fiber tanks 18, 75, and 100 cubic feet. The gun I bought says the tank size is 480cc. How can I compare the size of these bottles?? The 18 cubic feet must be with the bottle full of 4,500psi. How do I figure out 480cc tank when it is full, what is the volume? when I do a conversion, it says 480cc is .0169 cubic feet. I wish they would rate these tanks with just the empty volume.



Second question...........I could probably dig a little deeper and find this, maybe someone can point me to the different classes in competition, and the rules.

Why does most everyone use .177 cal. to compete? are they in general more accurate, or does it have something to do with cutting the bullseye line on the target?

I shoot competition with archery NFAA, and as long as you are touching the line.... the bullseye counts, so you want the biggest arrow that is legal to shoot.(you can be outside of the bullseye, but as long as the arrow is touching the line it counts as a bullseye.. Sometimes we have to keep track of inside out bullseyes,(for a tie breaker) and then you see some pro's using a really skinny outdoor arrow because then you don't want to touch the line at all. 
 
It is a bit confusing at first and tank size is not a major issue. Pressure is the main thing not the volume so don't lose a lot of sleep over it. The volume in your tank helps to determine the number of shots or the number of fills you get. I personally only have a small Crosman tank to refill my guns, not sure of the size but I get five or six fills out of it and around a hundred shots per fill so plenty of air for many matches.

As far as caliber goes stick with .177 if you are going to compete in silhouette, field target, or 10 meter bullseye. Power is not real important because you are only knocking down targets or paper punching with farthest distance of 55 yds. The pellet path is flatter with the lighter faster pellet. Also you are limited in power by rule 10 meter guns are only 6 foot pound affairs and 20 FtLb is the limit in field target so there is no need for bigger or more powerful airguns. Higher power would damage targets.

Hunting an bench rest are different . They are shot at longer distances and with live game you want to deliver enough power at the target for a clean kill. There bigger guns make sense.

Hope this helps. Get out to some matches and talk to some shooters and things will get less fuzzy.

If you have a compressor small tank will work fine. If you have to depend on an "away" source of air you will probably want the 100. 

Basically 177 for targets 22 targets and small game (birds rabbits etc) 25 hits a little harder then the 22 but it's probably too much for targets. For the average shooter 22 probably best. Unless you can have several which seems to be the norm in the forum

Sorry, can’t get my iPad working on the site. 

Anyway, first question , back at ya. What caliber gun did you get and what’s the primary use?

I bought .25 because I will be hunting and plinking in my back yard. I don't have any plans right now of competing. 

I am curious about tournaments, and why the .177 is popular. Just thought it might have something to do with cutting a line on a target. I'm not sure where I would go to check out any tournaments. Is there anything close to South Dakota?



So, anyone know what cubic feet a 480cc tank has with 3,500psi?



Thank You

A .177 is the choice for most Field Target competitors because some kill zones on the Target faceplates are 3/8” in diameter. Obviously, a small pellet has more room to strike the KZ without catching an edge and splitting the pellet. (Usually a split pellet won’t have the needed energy left to trip the Target) Of course, a faster velocity means a flatter trajectory so that’s another big reason why .177 is the choice of many.

As far as fill tanks go, check out the link already supplied. Just for info, you may already know this but, the larger the tank the more fills you will get out of your 480cc rifle bottle I have a RAW in .177 with a 480cc bottle and use my 97cf “Great White” tank to fill the bottle to approximately 3200psi. I get a lot of fills out of the larger carbon fiber tank. I’m guessing but probably around 50 fills. The cf bottles are started off with 4500psi and when the cf tank gets down to 3200psi I will refill my cf tank. I get approximately 125 shots out of each fill. 

I hope that helps and is the question you were asking. 

Best, Gary

.177 makes more sense for most airgun competitions except silhouette, where .22 is an advantage for the same reason as your archery example..

thanks, that is what I was wondering about cutting the lines. I am starting to find some info on competitions. I found a club not to far from me and they meet every tues. and thurs. 

I'm heading down there this evening and check it out.
