We spent a good while setting a photon up on my pals Sako quad .22, couldn’t get it to hold zero. We carried on trying, then it fell off the gun? I don’t think he’d tightened it down very well. I was quite impressed with the pard that he’s now got on a t-bolt. Strangely though, we couldn’t see some eggs on a wooden beam at 100 yards. We could see the wood and grass, nettles etc clearly, but not the eggs? Looking through a standard scope and yes, the eggs were there, crystal clear. Very strange, but apart from that oddity, I like the pard better than photon?.
