115 DTAC's - in a 243 -With H1000

[Just Dave]

Need some confirmation for a load start point.
I have a 26" Mullerworks 7:75, chambered in standard 243. I originally had it throated for the 105 Hybrids, but would like to give Mr Tubb's bullets a try. I can only seat them out to 2.715" max, before Im into the lands.
After much research, I am having trouble finding a good start load, I have read one recipe that had me around 47grain, but others were down around 42-45 max . .
Anybody else mess around with this combo ?
