It's his Mrs. She also shoots. Most everybody of my acquaintance shooting long-range BPCR shoots with a tang Vernier sight - I do for up to 600 yards with my Winchester High Wall. Look up the Montana Vintage Arms website for more info on Vernier sights.That is the second time I observed an Australian shoot while his wife, daughter, or girlfriend was helping spot. I'm impressed. My wife just says, "have a good day" and that's it. Do you think a quality vernier sight would improve shots at long range?
