Warning Minor Hijack
Browning A5 is a long recoil design, not inertia. Mind you, the inertia tag is a just a marketing gimic as the design is more properly termed a short recoil design. The difference is the length of recoil stroke. With the A5's it's the length of the shell before the bolt unlocks barrel goes forward, the bolt is released to follow. Short recoil has the bolt unlock then travel reward as the barrel returns to battery. Most belt fed guns are short recoil. There are only 4 functional self powered semi auto designs, Long recoil, short recoil, gas and blow back. No matter what name manufacturers give, ever action is one of those, the same for any type of semi auto fire arm. (if you choose you can call delayed blow back a fifth type, but it's more properly a sub variant of a straight blow back)
Personally i'd take a gas gun such as an M4 or Versa Max as they are far more tolerant of different loading levels with no changes. Mind you the short recoil guns make great hunting tools if you don't worry about shooting light target loads with them, and are generally lighter to haul around.
