QL request for 25-06.

[jr1968]

Can someone run a 25-06 QL?

Prvi brass.
100gr. Hornady IL
CCi 200 primer
H4350 powder
22In barrel

Thank You.

jr, the brass make is of no consequence in QL. However, its capacity in grains of h2o is, and it does make some difference. If you can provide that it would be good.

How about instead of prvi, Hornady brass

Won't mean a thing, jr. In QL you enter the case capacity as defined by how much water it will hold, in grains. Of course there is a default value for case capacity and it will give ballpark results using it. The result looks like this:

Cartridge          : .25-06 Rem.
Bullet             : .257, 100, Hornady SP 2540
Useable Case Capaci: 62.828 grain H2O = 4.079 cm³
Cartridge O.A.L. L6: 3.250 inch = 82.55 mm
Barrel Length      : 22.0 inch = 558.8 mm
Powder             : Hodgdon H4350
