Ive been shooting the 80gr Berger Varmint bullet out of my .243, these are one of my fire forming loads to the .243 AI I load 44.0gr of H4350 According to most reloading manuals I should be getting right at about 3200fps but when Running the loads through the Chronograph Im getting 3480fps Im shooting a 26" 1:8 Broughton Barrel.........................
Can velocity's vary that much from the reloading manuals. I realize that my barrel is 2" longer but that much difference?
