[QUOTE="merbeau, post: 1579747, member: 38494"] I have seen Ladder also used for charge testing. I typically follow Tobby Bradshaw's regimen for my testing. Basically anything less than 30-06 the initial charge should be in 1 grain increments and the final should end with either zero or 0.5 behind it (e.g., 44.5 RL 17 powder. Anything above 30-06 should have initial test at 2.0 grains and the final should end with a zero (e.g., 88.0 grains). So I tested initially at 1 grain increments to find a load providing a group of 1 inch or less and then went back and tested at 0.5 increments. around that load. I typically seat my bullets out near the lands to start with which tends to keep pressures lower. I will then try various seating depths to see if there is any improvement. [/QUOTE]
