Thanks guys - this info and what I gleaned elsewhere is quite helpful.
I am using handloads (of course!) 174gr BTHP at about 2300 fps. My front sight is a 0.015 and I am using the flip up sight set bottomed out at a 100 yd target. The peep sight ("Battle Sight") is zeroed for 250 yds so I won't be using it.
I understand that:
- the No4 and NoI MkIII sights work, but you need to add 60 thou, e.g. a LE -0.045 = a P14 + 0.015;
- on a P14, POI will change 1" for about every 0.009, so if I need to raise POI by 10 inches and have a +0.015, I'll need to go with a + 0.105 (Enfield + 0.045); and
- Springfield Sporters sells a "Front Sight Assortment" of five different sights for the LE for $7.
