Someone with OuickLoad or

other good ballistics software
Would you please
Run the data for 7-11 grains of Red Dot
45-70
378 grain Ranch Dog Boolit

14"
16.125"
28" barrels

Pressure and velocity, but most importantly pressure.

Unfortunately one of the most important, but least functional parts of my Load From a Disk program.

QuickLoad seems to be the best out there, unless a member knows of something comparable/better.

TC,

You would have to have some things to build in proper data for a specific bullet to get the software accurate. But using a standard OAL with a Lyman 457124, 7 grains is 11,500 psi for 816 to 936 fps (short to long) 11 grains is 22,000 psi for 1050 to 1148 fps.

Real problem here is that you are using so fast of a powder. The faster the powder, the wider the margin for error. Just so you know, you can be +/- 2000 psi just from using different cases.

So verify by chronograph with the lowest load if this is a weaker action.
