Maybe this is what I'm noticing on my EP5... I noticed mine are nowhere near as smooth feeling as my SH4 Gen2 scopes. I'm guessing it's just a different cut on the turret indentions to fit 10 MILs per rev vs. the longer spaced 8 MIL turrets on the SH4?My EP5 showed up today! Got one just to try it out. I have only mounted it up on the rifle and played around with it a little bit. The turrets are sharp and distinct, more so than the SH4 Gen II I have sitting on my 22 Lr. Looks good on the rifle so it has that going for it too. I have a bolt gun match tomorrow so hopefully will have a chance to zero and test it out more on Sunday.
When I said gritty and rough, I think this might be what he's referring to, as well. They're not really gritty or rough, just poor terminology on my part. I think his description of "sharp and very distinct" is more accurate, and the much louder spring-back sound might be making me subconsciously feel different about it, since I'm so used to the SH4 turrets...
