Thread: Thank you - First Handloads

50 rounds
I would've just loaded a charge weight ladder to start with maybe 12 to 15 rounds 3 at each charge weight going up in .5gn increments.
Find where your es is lowest and if acceptable tutu with the seating depth from there.
I only say this as components are in short supply and your gonna burn a heap of powder and pills there just with your starting point.
Most of the loads I have developed have taken less than 50 rounds some much much less.
If times where different and components were easily obtained I'd say go for it you'll learn heaps by going about it the way you are.
