I use the Athlon 6-24x50 on my HFT rifle. The matches I’ve been attending has seen a growth in using FFP scopes.
ive had problems finding the instructuons for the EVX 10x44i and the videos i find are of another model not mine... fill ,nme in...I assume you mean standard HFT as it is in the UK?
In that case have a look as the optisan evx 10x44i. I think that should be within your price range. Good glass (better than other optisan stuff thanks to fixed mag) and reticle.
If you can find a sightron-siii 10x42 that would be even better - more expensive than 400usd new but maybe you can find one used. They're stunning scopes.
