[QUOTE="Catskills, post: 2148636, member: 106302"] [B]With the exception of Weatherby ammo, I’ve never found factory ammo to be close to advertised velocities. Its not uncommon at all to see 100fps+ differences. I remember a couple that were worse: Federal 270 with 150 partitions at 2715fps, and Winchester 30-06 180s right at 2500fps. Because there are slow and fast barrels, it always pays to check. With the exception of one tight chambered 270wsm, Ive also found loading manual velocities to also be overstated by on average 75 to 100fps. Interestingly, fast barrels also exist. I have a 7mmSTW that regularly shoots 100-150fps faster than advertised velocities. A chronograph is indispensable in my opinion.[/B] [/QUOTE]
