That’s the thing - the biggest variable is the big lump of organic mush that is pulling the trigger, not the rifle of scope.
Case in point: I rocked up to a Bisley shoot with my club a few years ago with my Remington 700sps with an MTC Taipan scope on it and my Winchester 70 with a Nikon scope on it.
We were shooting at 600 yds.
The lad next to me had a Sako TRG with all the trimmings, topped with a £2.5k S&B scope.
His rig cost c£5.5k - more than both of my rigs put together, and I consistently out shot him all day. In fact it took him 2 details (20 rnds) to get it dialled into the distance whereas it took me 3 rounds on each rifle.
Not saying that I am an amazing shot (I’m not) but competence plays a huge factor in how well the equipment works and despite spending mega bucks on his kit, this lad was out shot by a hunting rifle with a £270 scope on it!
