AEA Possible problem with a Megalodon

What’s up air gun experts? I recently purchased an AEA Megalodon, I have enjoyed the rifle very much. I had no plans to do anything with it but use it as a long distance hole punch. After shooting it a lot I discovered it produces ample power to use it for deer hunting. Even without a moderator and even being a 50 cal the reduced noise when shooting the rifle makes it appealing to me over a powder burner for hunting and possibly even home defense. You wouldn’t go instantly deaf if you had to discharge it inside and so far it holds its air charge reliably. If I fill the tanks on my Megalodon to the max which is 4500 psi, consistently the first time I shoot it produces something like a half power shot. The slug or pellet will hit 6 to 8 inches low and you can just tell by the noise from discharging as well as the sound of the slug impacting being less tells me it’s around half the power it normally produces. My guess currently is the hammer is not striking the valve hard enough to overcome the air pressure enough to allow enough air to produce a full power shot. Assuming that is not incorrect what could be done? As far as I know there is no way to adjust the hammer spring, I would check the manual but it is an AEA product and they apparently don’t want to waste any paper or ink on anything like an instruction manual. Nothing like buying something you know very little about in general , then it arrives and you think they forgot to include the manual, then you start looking and find out they just don’t even bother with any manual. That fact may have caused me to choose a different brand for my first pcp. I didn’t know though and now I own it so I’ve had to ask a lot of questions to get going with it. This is the reason I referred to everyone as air gun experts at the start of this thread. I have found the answer to all my questions so far here on this site. I appreciate all the info so far and would also appreciate any info anyone might be able to share concerning the half power first shot from maxed out air tanks. If I stop filling the rifle at 4100 to 4200 psi I then get a full power shot without fail, so that is what I have been doing. I guess my question is do I need to even worry about it or just stick to 4200 psi ? I’m concerned the issue may become worse over time and I will regret not trying to deal with it now while there is a warranty, assuming they honor it of course. Thanks for reading all that if you made it to the end. Thanks in advance for any advice also.

p.s.- I’m not filling it inside and then taking it outside where the temp increases causing the air pressure to rise and exceed 4500 psi, I was warned about that happening before I filled it the first time. Just in case someone thinks that might be what’s causing the issue.

I have the solution to your problem I went through the same problem and figured out the issue...the problem is the bolt screw that sticks out to be able to de cock the rifle rubs on the half moon track when is charged to 4500 psi..is annoying but I took an Allen wrench to it and took it off and just have it in my rifle case if i have to decock the rifle manually I'll screw it quick decock it then take it off but that is the solution the bolt handle rubs on the frame and it does not let the hammer strike completely. Now i get full power shots at 4500 psi I put it through my chronograph and im getting 930 fps with the 230 gr texoma slugs

I had a similar issue with my T9. There is a small rod screwed into the bottom of the bolt, which is what cocks the hammer. If that rod is screwed out too far it will rub against the top of the hammer. You can clearly feel more drag/resistence. AEA and BinTac really need to invest in some proper loctite glue. Pretty much every screw in my bolt assembly came loose because of recoil. Including the bolt handle.

I think this explains why the gun becomes a little weaker. The resistance slows down the hammer and it'll hit the valve pin with less force.

I'll keep this in mind i just bought the t9 as a Christmas present to my self.

Well how much QC can one expect for an almost $1,000 airgun?
Kidding kidding, everyone knows the answer is more/better.

Not bad at all! Still trying to decide between 357 or 457. This will probably be next on my list.

That decision should be based on what use you want for the gun...I got the .510 but I was looking for stopping power and 900 plus fps speeds with 230 gr slug...cons ammo more expensive as you go up in caliber and less shots per fill.

Honestly I am looking for something a bit versatile. Something I can hunt medium game with, something I can get a decent amount of shots with as well to plink with.if I could get 457 stopping power with the shots per fill as a 357 I would be really happy lol. Might have to check on the difference in fpe between the two but rn it is looking like the 357 may be the one for me
