[QUOTE="Kiwi Greg, post: 2385778, member: 13456"] This may have been covered previously, start fast then slow down (opposite to conventional supersonic load development), don't use the suppressor until a stable load at 100 yards is found 1040-1080 fps is the "ideal" sub velocity, Sight in for 75 yards, it will be slightly high (1-1.5") at 25 & 50 then 4-6" low at 100 I have use subs on & off for years, first 308 then 300Blk & 450 Bushmaster, soon 350 legend hopefully I much prefer the 450BM with 220 Lehighs, impressive performance [/QUOTE]
