Hi guys. I'm after a favour, please. Out of interest I'd be interested to find out what pressure and velocity the following load is producing (theoretically) in my tikka T3:
Norma cases (don't know water capacity)
568mm barrel (22.4in)
56.0gr IMR4320 powder
GS Custom 110gr HV drive band bullet
Conventional jacketed bullet Quickload data will not be accurate(needs to be GS bullet selected), as these GS drive band bullets generate much lower pressures hence the higher loads.
A 57.0gr load showed a light extractor mark on the case head.
A 58.0gr load blew the primer out.
