Thread: Velocity/Powder question

Greetings @alanimal,
The components that go into a handload all vary as do the rifles that they are fired in. Generally data for pressure tested loads will show similar top velocities but sometimes with different charges of powder and this is what is shown by the two data sets quoted. Both top out at around 3,000 fps in velocity but the Hornady takes about 1.5 grains more powder to get there. Your rifle seems to need a bit more still. Some older lots of AR2209 were quite a bit slower than current production so take care if you move on to them. This is not unusual with a factory rifles compared to pressure barrels. Your rifle is also new so any extensive load development should be left until the barrel is run in. You are happy with the load so need to change nothing but you could work up to the Hodgdon/ ADI max should you feel so inclined. It is now spring so go shoot some stuff with it and think again about your next step in early winter.
Regards Grandpamac.
