ALTITUDE AND VELOCITY??

[260shooter]

Ran ballistics for a .30cal 200 gr SBT at 2950 fps, My elevation is 500 ft, at 5500 ft my effective range is extended several hundred yards. My question is, given a set load that pushes a 200gr bullet at 2950fps, will alltitude increase actual velocity?

I don't believe an increase in altitude will increase the muzzle velocity of a given load. You will see a benefit in that your trajectory will be flatter due to the thinner air and it's inability to slow that bullet as quickly as the thick air at sea level.

Thanks Dave

I thought so also, just needed confirmation.
