So I'm hand loaded for my first ladder test. .308 FGGM 175 IMR 4064 38.5 up to 43.5 Fed brass CCI 200 primers. Gonna be at 300yrds. My question is how "tall" should my paper be with that load range? Really don't want to loose any and don't want to look like an idiot at the range with a 9ft tall target(exaggerating).
