You should have taken the Blue pill !
Stupid question, but what is SD?600 yard bench rest is a great place to start. Choose a popular round, get one rifle and 2 barrels and focus on your reloading. Get your SD down to 5 and then go to 1000 yards. Wind reading.
Standard deviation. That and ES (extreme spread) are the Holy Grail of reloading. Muzzle velocity variations cause vertical spread. This is controlled in the reloading process.Stupid question, but what is SD?
Also Sectional Density - It's in every loading manual at the description for each and every bullet. This is why acronyms without context are weak language. In this case there is context. Like "AI" Ackley Improved or AICS magazines etc. . . ..Stupid question, but what is SD?
