I have a 90's model 70 classic in .300 wm with the BOSS, it's a shooter. It shot near moa with green box 150's and 180's and .5-.6 with 168g Berger hybrids. It's a completely stock action/trigger/barrel with a Boyd's stock on it.
I'm not quite that upset about it lol. It'll probably go on the shelf of backup parts. I don't want it to sound like I'm bashing vortex either, I have 2 others that have been great for their intended purpose. I was told that the pst was in the same class as a mark 4 or even a nxs for clarity and...
Possibly, but it doesn't seem like it's fogging. I live in a desert so mirage is pretty constant when the sand starts heating up. Also "couldn't see" was probably too strong, it was waving around a lot at any power level.
I'm no where near reading mirage (thanks for the word, it was bugging me that I couldn't remember) in my shooting, however it was bad enough through the Vortex that I couldn't see the target at 500 yds and had to stop shooting. It was still visible through the Leupolds but it didn't affect shooting.
