Quickload question on 6x45 load

[KurtB]

Did a lot of internet searches for load ideas for my 6x45. Currently loading a 95 Berger VLD at 2.53 OAL, 25 grains of varget, cci450 primer, Lapua 223 case necked up to 6mm. Would be very interested in seeing what Quickload shows that load at. I see no pressure signs and velocity seems inline with expectations.

In order of interest, I'd love to see Varget, RL15, and H335 with those load parameters above. PM is fine if anyone has a moment or two to plug those in. Thank you

VLD Target or Hunting?

 

[just_jon]

I went with VLDH and assumed a 24" barrel.

Different bullet with a G7 . Here is with an 18 inch barrel.

Cartridge : 6 x 45mm
Bullet : .243, 95, Berger Hunt VLD G7 #24427
Useable Case Capaci: 26.831 grain H2O = 1.742 cm³
Cartridge O.A.L. L6: 2.530 inch = 64.26 mm
Barrel Length : 18.0 inch = 457.2 mm
Powder : Hodgdon VARGET *T

Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.5% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

VLD Target or Hunting?

This is the hunting version. Appreciate all the replies. Will dig into those now. Thank you!

 

[asd9055]

@KurtB
The beauty of QL or GRT shines when you calibrate with real data, such as your MV, Atmospheric pressure and temperature as well as the average of water volume of 10 fired in your gun, unsized cases, barrel length and twist.

 

[KurtB]

The case capacity is different in jon's than what mine shows for a 6x45. Also, I used a different bullet with G7 ballistics... case capacity will make the big difference...

Tensilon, It looks like you had oal at 2.253. I'm using this in a bolt gun and chamber is cut to allow 2.53 oal. That is probably the difference. Thank you very much.

 

[KurtB]

I went with VLDH and assumed a 24" barrel.

Jon, This data seems to match up very closely to my actual results. I'll print these out for future reference. Thank you for taking the time to run this. My barrel is 18" but when I back down 6"x 25-30 fps per inch it is quite close.

Good god, you are right, how in the he** could I miss that....I changed it to what I thought he said and I put an extra 2 in there. I'll see if I can delete it.
