For running the majority of standard loads, the 2nd position in seems to cover it for most guns. This is only a bit firmer than the factory spring retainer with our Competition Spring Plunger.
The 10% drop of the Competition Plunger can be a bit much for the common loads used in most guns, but it sure is fun to cycle 980 FPS cowboy loads through a 930 all day long. The second position brings it closer to an 8% drop, which is working out well in everything we aren't trying to use for party tricks.
