that is how we did it pre Chrony days,
What cartridge bullet and powder? Someone on the forum will have access to the data.
Most jacketed bullets need an impact velocity of 1800fps to expand any more is a bonus.

cheers. Not worried about the data and start points, justr5 wondering how the sampler packs are utilised the best.
Without historical data for similar bullets, seems to be a bit of a lottery especially without a chronograph where you could pick a start point and look for velocity changes/flat points
