[QUOTE="pods8, post: 1057743, member: 83233"] Yes I have manuals. As repeatedly asked where exactly is your specific area of concern with the situation I've described along with my thought process? I honestly am open to constructive constructive criticism of it thus the reason I posted here. However currently you've only responded in generalities. Generally speaking many lead core bullets of the same weight will have a very close charge band for a given powder and as always start low and work up. This is how we deal with not having published data on a specific combination. This happens all the time as new bullets come out, its not so crazy to think about it in reverse. The manufacturer already paired the 140gr TTSX with a safe powder charge. Often we also see that mono bullets have a lower charge for a given pressure/velocity combination for the same bullet weight. So with those things in mind I've suggested taking the powder charge for a 140gr TTSX (which is likely a bit under max already for a 139gr hornady btsp) and also back it down another 2 grains and work it back up to full in .5gr increments assuming no excess velocity or pressure signs. I could back off a bit more but I wouldn't want to have too low a charge either but I'm open to suggestion. [/QUOTE]
