7mm-08 QL hulp

[muismaree]

Hi julle.

Kan iemand wat QL kan operate my dalk help met 'n lading? Info is as volg;

Kaliber- 7mm-08 Rem
Loop lengte- 560mm
Dop kapasiteit- 54.6 Gr
Die Tipe koeel- Hornady SST 139 Gr #28202
Tipe Kruit- S355 Lot 010
Die absolute maksimum TPL- 70.54mm
Die beplande TPL- 69.84mm
Tipe Primers- Rem9 1/2 LR

40Gr- 2544, 2559, 2565 fps
41Gr- 2600, 2627, 2614 fps.

Baie dankie!

Muis,Vergewis jou van die specs en maak net seker die regte gegewens is gebruik in die QL simulasie alvorens daar opgewerk word na die node.Daar is ook hoër node maar is kompres lading met s355 kruit as jy spoed ook wil jaag.

End of combustion after the projectile passes muzzle.

Die volgende node is 2783fps @ 53700 psi( geweer se specs is 60000 psi ) met 43.6gr s355 indien jy wil opwerk na die node.Sal ook eers moet spoed gee met vorige node lading om net te "double check"

Dankie Len, ek sal so maak. Die geweertjie moet net eers 'n kd op kry, maar dit sal dalk nog voor die naweek gebeur. Ek sal dan gaan skiet en rapporteer oor wat hy maak.

Plesier bly om te help.
