Feeding issue

[JWard79]

One possible compromise to your issue would be to use a CMJ bullet, which provides the profile of a FMJ with a sealed base. The HP rounds are popular because they provide a sealed base, but have a distinct profile requiring a more precise load and extractor tuning. A round nose profile allows for more deviation from the "perfect" timing and alignment required to run a HP setup.

In reality, the only advantage gained by using an HP or CMJ bullet is a cleaner bore and compensator. If you are willing to put in the time to visually inspect and clean these components, there is no discernible advantage. With this in mind, a high-tech bullet would suffice as well.
