25-45 Sharps load data

[thriller1]

I just got done building my 25-45 Sharps in an AR platform. I have the reloading dies and 90 grain Sierra Blitzking slugs in transit. Does anyone have any powder suggestions? Will I be out of line starting with 28 grains of H335?

I would contact sharps directly for proper data to start from. I honestly don't know of anyone that's got one to start you out.

Ran a chart in QL and they showed 25gn for max charge w/the 90gn sierra. That's everything @ default specs. 2.26" COAL and 31gn h2o fired case capacity. 28gn of 335 was something like 87k PSI peak pressure, way hot.

should be able to use 25TCU data as a starting point as well as its essentially the same thing, a 223 case necked to .257. Both have the same 31gn h2o case capacity.

Hot was my initial assumption. I looked up 6x45 shooting similar weights and 24.1 of H335 was max. Not apples to apples, but I was curious.
