Factory 123sst ballistics at sea level using 20 barrel? - JuanC - 05-01-2018
Just purchased a 20 Satern cut rifled barrel. Does anyone know what kind of ballistics the 123grn sst would be at sea level. Im 10 ft above sea level currently.

I've got an 18" Satern cut-rifled and it's a bit faster than average.
If Hornady specs their 123 SST at 2580 fps from a 24", and if you lose 100 fps average every 4 inches, that would put you at 2480, but given a Satern cut-rifled fudge factor I'd guesstimate your expectation at 2510?
