I run pretty much everything in moa as well and that would be my preference. But at this point with the shooting apps we all use, I figured what difference does it make, I just add the gun and scope to the app and it tells me what to set the dial too.
They are available, just need to know where to look. I wanted cci 200's only, and just missed them several times. Ended getting a case on gunbroker for a good price. Miwall currently has remington and winchester in stock, are they cheap no, but if you need them...
Varget may not get you the speed you want, try cfe 223, win 748 or staball match. I never got good sd's from cfe 223, but inside 300 yards it doesnt matter. I like the 130 and 150ttsx, tried the 110 but didnt like the performance. I run an 18 inch 308.
I did not have a good experience with their products or service. Bought a complete glock slide, firing pin was seized. They wouldn't give my money back but also didn't have a replacement. After several months of me complaining i finally got a refund...
