I think you’ll find round count will help here. These take quite a few to break in and properly run. 100 rounds or more, way more metal to mesh together and wear in. Think of bedding rings on a piston.
for what it’s worth, soft points can have some serious issues loading from a magazine in any AR. Big or small. Feed ramps do a number on them and they deform pretty badly. Manually load a round if you’re using it for hunting to keep the projectile in tip top shape. ( with bolt locked back drop it in and release the bolt)
