AEA Hp Max

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!

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.
 
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.

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. View attachment 423328
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.
