Quickload is only good if I can true it to your gun, burn rate for your powder, and anything else your gun might do. I can run it but it won't be anywhere close to accurate

My wife thinks I only have 3 guns

Can you send me your fired cases' capacity, then velocity for any loads you have shot through your gun? Then I can try to tune QL to give you accurate data

My wife thinks I only have 3 guns

Thank you !

I will cross-check data with Norma and Berger...

:wink:

Thank you very much for your help.

What information are you looking for? Velocity, pressure, etc... could you clarify more?

[jagermeister]

OK, here some results.

3 shot group each load, @ 184 yds. distance :

73 grs.

75 grs.

77 grs.

I think I'm gonna give a try to the 73 and 77, although, if the results repeat themselves, I'll be more likely to go with the heaviest load, as difference in Velocity may be substantial....

Your thoughts ?

:mrgreen:

 

[BrushyHillGuide]

I think you need to invest in a chronograph. Load development without one is like trying to load with one arm tied behind your back. Plus, QL really needs velocity to produce accurate results.
