Middag manne.

Lading Norma doppe

Kruit H4831SC
Ek het 57 gr gegooi.
Drie skote het as volg gemeet

Ek het gemerk dat die slagdoppies kraters vorm waar slagpen tref.
Niks ander druk indikasies is opgemerk nie.
Ge vuurde Doppe se H2O is daarna gemeet 72,4 72,1 71,8
Ek het data gebruik vanaf Nosler se website vir die 280 avkley met 160 grein punt.
Volgens die data het ek n dopvulling van 91%
Is daar n ander dryfmiddel wat my beter dop vulling kan gee.
Dk het geloer na RL22 Norma MRP,Selfs gewonder oor somchem S361.
As iemand my op quickload kan buhulpsaam wees sal ek wardeer.

Your burn rate is well above what it should be and all indications are that your bullet is in or very close to the rifling.
Your MV is probably about 80 - 90 fps higher than it should be.
Did you measure the jump at your very long TPL of 89.0mm

How did you get the chrony to read accurately at an indoor shooting range. Did you have an artificial lighting kit on the chrony ?
