Ahhh yes the EFR. I had a very confusing and poor shoot at the old Southampton Buccaneers ground, using an EFR on top of a FWB P70FT on a hot sunny day. My son easily outshot me with his S300 / Custom Shop combo.
My old 20-50 moved very little in the cold and not at all in the hot. My present one is a little more temperature sensitive. My Sightron SIIIFT seems very stable in the cold, if we get any worthwhile heat this summer I will find out what it is like when things warm up.
Five different pointers on a £2,500 scope, hmmmm.
