Just got my first pcp, an AEA Hp Max 457. I'm really liking it. As far as fpe and accuracy goes. If there anyone out there has had both? Which did you prefer, why?
AEA Hp Max
- Thread starter Flyingsherpa
- Start date
I have one I bought in .510. I installed the 22 inch barrel on it. Accuracy was ok but not good past 50 yards. I was getting 400 plus fpe on first shot. Averaged 368 for 6 shots with 700cc cf bottle. Just bought the .457 barrel in .22 Inch. There is way more ammo selections in .457. I hoping I can get better groups with it. I woukd like to shoot a 100 yards or more with it.
Happy Holidays!

I installed 22 inch barrels and 600 cc air tanks on my 45 & 50 hps but did not change probes. It was very easy to change barrels they are threaded. Loosen lock nut and unscrew barrel. After install new barrels insert magazine and adjust tension so mag just moves in and out. Hope this helps.

Looking at it this morning it looks like I will have to take the stock off too so the 50 cal bolt will clear the housing. I think Bin offers a piece to use buffer tubes and eliminate the folding stock piece. I'm sure someone will chime in. If not I know Bintac is great with customer service issues. Do you like the 45 better now? I have a hp max 45 and was considering if the barrel and tank upgrade might be worth while.

It was pretty easy. You have to take the stock off. There is a little Allen head screw in the back if bolt you back off some to pull bolt handle off. There is a small screw on side of bolt you take off. Not to bad.

Just shot the .457 at 30 yards and I like it much better so far. The pro slugs(205gr) on the left did the best. Mr HP 216 
grains on top were a close second. AEA 243 grain came in third.

Have not had a chance to try them out with holidays and work but here is image on my .45 with 22 inch barrel and 600cc tube.

+1. I'm very interested as well. I have the 457 barrel coming on Saturday. I feel it's a better fit than the .495/50 cal barrel for this rifle. I'm hoping this rifle will shoot decent out to 70-100 yards.

What is the deal with the Max in .457 and .50? According to Aea you have 4+ good shots with either gun. They share the same mag. and airtank capacity. With everything I have seen on YouTube. The .50 gets more fpe than the. 457. Even with thy same gran ammo. I have heard a few times that they are the same gun

They do appear to have identical chassis. With out opening them up and checking port sizes and what not I would think the m50 would have larger ports. I don't have anywhere to chronograph anymore or else I'd be posting numbers with my max and m50. I do appreciate hearing what others are getting out of them. Once I get mine swapped I plan on taking them out.

I got the kit yesterday. Pushed a couple different slugs through it last night. I had mixed results. The lucky seven 152&246 gr max velocities had hardly any rifling however I also pushed one of his meat punch slugs through and the rifling looked pretty good. I'm getting some Intel on how to swap the bolt then I'll do it.

There isn't squat for info out there on changing the bolt so I just started taking it apart today. Once all the pieces are out of the chassis I removed the spring and guide then slid the bolt back to remove the hammer. Then I loosened the underside shoulder bolt type screw. Which could be swapped out with a hex Allen bolt. Once that was loose the Allen bolt on the backside of the bolt is loosened and the bolt/ bolt is removed you can slightly rotate the bolt making it much easier to remove that shoulder screw. Once the screw is out just slide the bolt out the back. I like that the hammer can be removed without having to mess with the trigger group. Depending on how cold it is this week I might take it out to the shop.

Here's a 6 shot group sight in at 50 yards. Pro slug 195 LH FD swagged. 3 shots to bottom was sighting in.

Nice group. Do you know what kind of energy your getting with those 195's? I just shot some Griffen 200gr dish based. They feed and cycle great. Going to run them over the chronograph soon. I want to see how they compare to the aea 195gr.
