I would have thought that the most important aspect of buying a good HFT scope would be the style of Ret......how else do you rangefind?....If you can bracket useing the ret you're 75% of the way there. I know that not all the kill sizes really are 15,25 & 40mm(although they really should be ) but being able to accurarely judge the range is paramount?.......i personally use a combination of eye first and see if my bracketing marks concur. .
The current dark horse on the HFT circuit is Brian Samson, PM him and ask what scope he's using....he's a nice bloke and i'm sure wouldn't mind. For me its a SR6. It seems to be working(58 out of 60 at Ponty) and there's not many i miss due to mis-rangeing
With the SR6 set at 10 mag and a PA of approx 35yds i can see from 55yds down to approx 15yds....anything under 15yds is a bit blurry so thats where the mk1 eyeball comes in.
