Interestingly enough. Sierra's start load for the 270 wsm with H1000 is lower than the start charge they list for 270 win. Using same powder and bullet weight.
Add to that the different rifles they use and the other unknowns between them all as listed above and you can't say that there is consistency between them at all, SAAMI notwithstanding.
For me to start at Sierra's start load and work all the way up to where I feel like I am gonna be with this rifle will take me several boxes of bullets and pounds of powder.
Yeah I will have to check that out.not necessarily, like I suggested in my first thread do one or two rounds from low to high for a pressure test working your way up. Start the load development in the range where the velocity is where you want it once you are sure the charge range is safe. I have been getting some great results from what I call the 55 round load test. I just made a thread on it, you might want to give it a try. It's worked twice in a row for me
