Apm50 shell ejector and upgrades

[Zfurlong]

Hey guys, I was looking into that apm50 co2 shell ejector sniper rifle and read that the skull and devil shells exceed 600 and 800 fps on .2's respectively. So I thought to myself, if it has a 6.03 inner barrel stock and gets 600-800 with those higher shells. then would using a widebore with those higher pressured shells cause enough of a joule drop due to the larger bore, to allow those shells to fire within a 450-550fps velocity?
Would this combination paired with a modified hop system/style, be a viable gas/co2 sniper rifle?
Would this combination make for a viable shell ejector sniper rifle?

Thoughts?

Thanks again in advance for your thoughts and opinions

No.

Why would you buy 600-800 fps shells instead of shells that are in your limit?

Read from the 51st word to the end of the post, there's the answer.

I don't see an answer.

The concern here is why you're aiming for such a high FPS? Even with the widebore and if it drops as much as that, you're playing with a dangerously high joule level and FPS. I wouldn't exactly call that viable.

Huehuehue you are so smart and clever.

Except you're not and want to cause other players injuries. You think its okay to play with 600-800 fps shells? In a SNIPER rifle none the less? I really hope you are one of the new kiddies to airsoft that think they wanna be a COD sniper and think it will be super fun and tactikewl.

A WIDE BORE in a sniper? Really? Also shell ejecting? Hope you enjoy spending most of your time scrounging around for your shells.

Everything you have posted paint a picture of an incredibly inefficient and dangerous snipe rifle.

just as an FYI, my apm with devil shells shoots 800 fps with .3s not .2s, its over 1k with.2

Damn, you can likely use that for pest controll with some of those bbbastard pearls lol.

And to the OP the gun you are talking about is more of a plinker/show n tell kind of gun. Its awesome, likely a bunch of fun to shoot. But not practical for gaming (it would be okay if you were stationed in one place with a team protecting you but constatnt relocation will have u chasing shells all over the field.
also even the best gas setups are not all that consistant and consistancy is the most important thing for sniping.
and on top of that for gas sniper rifles you are normally limited to 400-450fps MAX. the energy properties i gas guns are not that safe for high velocities with heavy rounds.
And lastly having such a loud gun when stealth is your greatest advantage is kind of pointless.

In an aeg, you need a correctly ported cylinder to match air volume to your barrel length. Diameter plays a big role as well. What I am asking is if the skull shells would help provide the correct air volume for a widebore. The reason for the widebore would be to eliminate/minimize the bb bouncing in the inner barrel as it travels to the end of the inner barrel. Bb bounce happens more in the tightbore barrels than it does the widebore. This has nothing to do with wanting a high fps gun. If I wanted a high fps gun I would simply throw an m170 spring in an aeg and call it a day. So rather than harping on me about the stated velocity of the shells ON STOCK PARTS, think for a moment about everything I stated in the threads first comment. Take into consideration the parts being used, the length of the barrel, and the diameter. Co2 expands to give the velocity it does. By providing a larger space for the gas to expand, would that therefore not decrease the amount of energy being exerted on the bb itself?

And the velocity limit for my local field is 500 for bolt actions. To my knowledge they don't care wether spring or gas.

I am well aware fps does not equal range. My ump shoots 360-370 on .2's and outrages most guns it's gone up against due to the air seal and hop mod in it. And it's not the fps that I'm after. What im after is the correct air volume for the 6.2-6.23 wide bore barrel.

Anything shell ejecting is more trouble than it's worth, even worse when it takes multiple modifications to get it to fire anywhere near field-legal velocities. On top of that, you've got to deal with the inherent power inconsistency of an unregulated gas source, which handicaps your accuracy.
If you wanted to buy one for shits and giggles, by all means do so, but don't try to pretend it's 'viable'. Even with all the problems worked out, it's at best reinventing the wheel and you'd be better served by a spring or regulated HPA bolt action.

EDIT: Didn't see Hectic already said basically the same thing. I'd say then that if you're really interested in seeing the effects of combining widebore barrels with an otherwise extremely hot rifle, then try it out yourself. I'm almost certain nobody else has tried it before, for the reasons you've already heard. Be sure to report back on your results here: if you discover some miraculous secret to perfect accuracy I'd be happy to hear, but until then I'm not holding my breath.

I think you need to do some more research on how airsoft works. The BB doesnt really bounce in the barrel like some tight bore manufaturers would have u belive. The BB will have a cushion of air around it helping it stay centered in the barrel.
also about the volume matchIng. run a heavier round. It will take longer to travel the barrel thus using more of the volume.
and lastly. If going from a stock widebore to a tight bore gives a 5-15fps increase you could assume the losses would be simaler going wider. so say best case maybe u can drop 30-40fps going from a tbb to a wbb
