Shooting NSA 31 gr slugs in my FX Impact PP 700mm Slug ”A” barrel with CF liner and CF outer tensionEd. Here is what is happening and then my quandary. Shooting 1000 fps zeroed @ 50 yards. I’m using Sterlok Pro set for the NSA 31 slug, G1. Reset scope (Element Nexus) for target@170 yds. Take shot and slug lands 0.9 MRAD high. Shot again, same impact point, so JFTHOI changed factor to GS. The next slug landed slightly lower but still high. I new G7 would never work, so I set RA4 and shot. This slug landed almost exactly where I was aiming. I should add that this was early morning shooting with no wind, mid 80’s Florida humid day.
Question, has anyone else tried using RA4? What were your results?
Otherwise, opinions on why I have these results!
Thanks before hand, all thoughtful thought welcomed.
