I want to try and match the velocities and see what the groupings are like. But per the advice I've been given I'll start at 4.8gr which should give about 1000fps and work my way up to 6.4gr which should give me about 1200 fps. And which ever load between the two that gives me the results I'm looking for I'll go with.

Load no more than five rounds at each charge weight as you work your way up. There is always a good chance that the lighter loads may not work the action properly.
When you get the results you want for both accuracy and velocity, load up a larger batch and verify your results. If your first accurate group was an anomaly but still functions the pistol, you can still shoot them. There are few things more frustrating in life than having to break down 50 rds. that don't function in your pistol.
