In tuning my lvl 10 that I just received, I noticed that the mod works the same with different numbers of shims in the powertube. Are the number of shims important to how well the lvl 10 works? I think it might from logical reasoning:
1. If there are very little to no shims in the pt, venting will occur later in the firing stage (very little later since the shims are very thin) thus when the gun is shot, the bolt is moving full speed for the first few milliseconds after the sear releases the bolt - before venting occurs.
2. If there are many shims in the pt (not so many that it leaks constantly), the venting will occur right after the bolt is released and thus provide an immediate reduction in the speed of the bolt.
Should you have as many shims as possible in the pt, but not so many that it leaks - so the bolt will be soft all the way through the first stage? How many shims will make a very effective lvl 10 possible?
