I am running a light load of H1000 @ 2843 but can get another 100fps conpressed. If you go to double based powders like N565 or RL26 you can run 180’s a bit over 3000. Obviously bullet design factors in...180Bergers are faster than 180eldm’s.What kind of velocities are you achieving?
For me the weight saving of a carbon fiber barrel came at such a cost barrel life is important to me. H1000 gets me single digit ES without a lot of effort. The extra 10–200fps wasn’t worth it on a ballistic chart to push my barrel hard but it is for many who seek the max speed.
The 7SS is best for a short action. The 7Max is designed for a medium action and the 28Sherman Magnum is designed for a long action.
Here is a link to reloading dara for Sherman cartridges.
I have put together data from the many shooters that emailed/PM'd me. Here is what I have so far but I am still asking for more data to be PM'd to me so I can continue to add to this. Thanks to everyone who contributed to this. As always this data is for specific rifles and should be worked up...
