In years past, we were always instructed never to leave ammunition loaded to the gills in magazines. The thought was that over time the spring's return capability would be weakened and possibly lose its effectiveness. I've heard it expressed that modern metalurgy produces better springs, more immune to this "memory loss" and it isn't a problem to leave the mags full. (I usually still leave out a few rounds to this day out of habit and concern for the spring.
Now, the Drozd magazine spring is pretty stout and crams 30 + BB's up and snug in position for that precious little blast of CO2 gas to send them barreling toward the target. Does it seem remotely possible the spring might slightly hinder higher velocities holding it in battery at the top of the mag so tightly?
My question is, would it hurt to just leave the magazine filled with BB's to possibly weaken the spring just a tad...deliberately? Thus, the gas wouldn't have so much tension to overcome therefore increasing the velocity of the escapee down the barrel?
Any ideas on that? Was it clear enough what I'm trying to say? Please feel free to shoot .177 holes in my thoughts here. I'm curious.

When the spring is compressed the least, as it would be the case with the last BB’s in the magazine, there is less force pushing those last BB’s up toward the top of the chamber. There may be some residual Co2 from the previous shot that pushes the following BB out of the magazine right after the shot (all of this happens very quickly) and that second BB, since there is not that much force holding it, either falls off the front of the barrel (if you happen to be pointing it down) or stays between the the magazine and the barrel and then falls to the ground when the magazine is taken out. I do not know if this or something similar is what is happening, but I do know that this only happens when my magazine is close to empty, so there is one reason for me to rather have a “stronger” spring than a weaker one.
As far as the spring compression affecting velocity, I would say probably not, but I am going to test some lead BB’s I just received with the chronograph and I will also run some full magazine vs almost empty magazine test with the steel BB’s to see what happens. I will post the results.
There is something else that puzzles me about the BB feeding mechanism of these magazines, due to something I noticed last week while I was farting around with the thing in my garage. I have another theory but it is too far fetched and I don’t want to elaborate before I check the magazine internally to see if I am right or not………… More on this later.
