[QUOTE="rodneymoncrief, post: 1415536, member: 29572"] I have a HS Precision SPL in 280 AI shooting 150 gr. Barnes TTSX using IMR 4831, Quickload stated that my muzzle velocity is 3016 fps. Shooting at 500 yards group was 1 MOA high, also at 600 yards 1 MOA high, both groups were .5 MOA at those ranges. Here's my question, using the Gseven ballistics website it stated my muzzle velocity was an average of 3212 fps, is such a high velocity possible out of a 280 AI using a 150 gr. Barnes TTSX? [/QUOTE]
