I like it. Shot from, through, and into just about anything it always gets from .50 - .60.
Looks like the amount of silicone sets the exp; the more you have to flatten, the wider it is when it flattens, and it does seem to flatten _every_ time no matter what.
Accurate, very low flash, clean.
Should be as good as any other 124 +p out there, or very close.
