[QUOTE="Calvin45, post: 1649870, member: 109862"] An excellent point about the often massive difference between test barrels and the barrels we actually use. And of course as is always said, each rifle is a law unto itself, there are indeed fast and slow barrels out there. I’ve also seen, counter to what you’re told to expect, a shorter barrel run faster. Not much, but still notable. My 22 inch savage 270 surprises me, the federal blue box is advertised at 3060 fps and it chronos right at 3050. In my friends 24 inch rem 700 same ammo was right at 3000. In my savage 99 243 22” the rem Corlokt 100g advertised 2960 and, get this, chronographed 2780!!!! I haven’t shot factory ammo in years now but this shows that if your trying to shoot to any real distance, you need to know the actual velocity, from a chronograph, as even factory numbers don’t always check out. As a side note, while many call noslers load data optimistic, it was spot on in my old weatherby vanguard with 150 grain bullets and imr 4350, getting a chronographed 3400 fps with the exact same charge weight they used to get that speed. I thought it was weird actually, that never happens. All in all you’re right, it’s the exception. The difference in capacity between brass manufacturers alone, and even from lot to lot, ensures all data is for reference, a guideline to be used responsibly, not starting with max, and I’ve never regretted how I went about getting into reloading. Before I bought a press or any components, on what was at the time a college student budget, I bought a chronograph. I had come to the conclusion in my research it was probably the most important piece of equipment I would need, I think of it as safety equipment. [/QUOTE]
