I believe about 90% of the short stroking issues are a result of low pressure ammo in current rifles. It seems that early versions of this rifle had relatively rough chambers which were causing some issues with extraction, short stroking and broken extractors. My BFG-50A however seems to have a very smooth chamber. Time will tell.
One also needs to realize that when you handload for a 50 BMG, you want to load it to the 50 to 55,000 psi range and no more. Loading it to the point where the pressure will permanently deform case brass will also result in a lot of problems. These huge cases have ALOT of baring surface to the chamber, if you load them to high in pressure, that's ALOT of grip that has to be overcome to clear a fired case.
Point being, the 50 BMG is a relatively low pressure chambering, load it to its designed pressure ranges and most function problems tend to go away.
Just got my APA bipod in and will be moding the Serbu to mount that bipod as high as possible to keep COG low. I also got the leg extension kit and extended cant locking lever, should be a good fit, just have to get the rifle converted to allow it to mount the bipod.
Glad to hear your happy with your Serbu, how long have you had it and how many rounds do you have through it. I would agree, running 10 rounds through a 50 BMG is certainly an event to witness as a shooter and witness!!!
