Working back up" serves little purpose. Pressure signs are meaningless in straight walled pistol cartridges. The only way to know what pressures you're running is to abide published loading data. Which includes primer selection.
I'm telling you that pressure signs in straight walled pistol cartridges is an indication of nothing. I'm saying that you can be well below industry maximums and see so-called pressure signs. I'm saying that you can be well over industry maximums and see no pressure signs right up until the gun blows up. I'm saying trust your data and check it with a chronograph.Are you saying that working up straight walled pistol rounds is a waist of time? Are you saying it is safe to start right at the max load? Are you saying published load data is a recipe and must be followed to the letter? Are you saying that the pressures listed in the manuals will hold true in every firearm? For example, if the manual lists a pressure of 30K psi with a specific load, would that 30K psi hold true in every firearm the load is fired in?
Well a lot of guys say NO to titegroup in 40 as wellWhat is wrong with TG in a 10mm? Assuming you are not trying to hotrod it to max 10mm velocities, and using it within its intended window, it shouldn't be any different than using TG in a .40.
If you are already at a starting load I wouldn't worry about substituting the magnum primers.

Published data is not an absolute. Variations between firearms cause variations in pressure. That's why we have a safety margin, to cover those small variations in pressure. As long as your chamber is within spec then pressures will be within acceptable range.How will following published load data "to the letter" tell me what pressures I am running at in my firearm? Is published data an absolute and pressures will be consistent in ALL firearms?

Then I guess you're a smarter guy than John Linebaugh??? I guess he didn't really test guns to destruction and see no pressures signs right up until they blew???Not semantics, poor and potentially dangerous advice.
Telling a fellow handloader that "working back up" is a waist of time. Pressure signs are "meaningless". Following published load data can predict pressures. All Bad advice. Semantics, I think not, bad dangerous advice, period.
It's bad advice to advise a fellow handloader NOT to deviate from published data? It's bad advice to advise that you may be over safe pressures and see no signs? It's bad advice to advise to always check your data with a chronograph?
