Loaded some of these 800 gr. Hornady projo's. Yes...they are longer and must be seated deeper if used in a semi or belt fed. Loaded all mine for an FA M2HB....but too expensive to shoot that way..LOL. Only shoot them sparingly in a State Arms bolt gun.I believe they load to fit into semi auto mags, which would be 5.45". Any longer and it won't fit and will have to be single loaded.
The other thing that you need to remember is that the AMAX is a BIG bullet. And when pushed down that far into the case can cause pressure issues. If you reload them start out lower and work up.
The factory stuff should be fine in your rifle, just watch for any pressure signs.
Loaded in 2001,there were 2-bullet weights...750 gr and 800 gr. Apparently,they dropped the 800 gr from their line...? I remember because that was the heaviest .50 BMG bullet I ever loaded...and the most expensive...!!Amax are not 800 Gr. they are 750 Gr. !! I just checked their 2016 catalog it states 750 Gr. FWIW

Does your BFG 50A have a preference for other types of ammo commonly available? Most of what I come across is Lake City manufacture M33 ball ammo usually with an '09 or later production date and sold either linked or in lots of 100 rounds. Other commonly found ammo is PMC Bronze ball ammo or the PMC X-Tac ammo with brass projectiles. Have you run any such ammo through your Serbu and, if so, how did these other rounds function? I haven't bought a 50 cal yet but I'm leaning towards the Serbu because I like the gas operated design of the action as opposed to the recoil operated action of the Barrett. The Serbu also doesn't need to be broken down in order to store it in its case and it's lighter than the Barrett. Thanks.I shot the some amax I bought this year in a Serbu BFG50a semi auto I got late last year. Ran great and was very accurate.
I have not tried the controlled fracturing bullets yet. It looks like the inner bullet is just pressed in. They are advertised as sub sonic and I was worried about expansion before the brake as I was going to used them at supersonic speeds. It says that they are machined from solid bar stock so they should hold together. The other frangible bullets, I had previously tried were the 600 Gr. round nose ones from poly gun bags, they were good for no ricochets but did not disintegrate to transfer energy well and just made holes. The Leigh close quarter bullet also looks cool for expansion, but the weight is awful low. I might get some of those for pumpkin blasting also.DRH,
How do they hold the bullets in place on the frangible bullets. If it's not secure it's going to cause all kinds of problems right from the start.
Guess I might have to go to their website and check them out, very interesting looking bullet.
