Ek skat 1-12 of 1-14 want 65gr gamekings kom dwars by die teiken aan.

I assume you using S321
26.4 grains for 3219-15 fps on the chrony @ 59000 psi
Your 25.0 grain load is on the lower node @ 50 000 psi

As mentioned just check the stability

Your case length is also longer than SAAMI spec. be careful you do not squeeze the neck into the leade area and create a pressure spike.

Met 50/55 gr koele behoort hy beter resultate te kry. Ek twyfel of die 60gr baie beter BC het om die wind beter te fnuik.

Thanks Dale
Cases are most likely multiple firing without trim.
s321 correct.

Wil advise accordingly.

Ek het 55 gr vmax voorgestel maar hy het toe klaar 60gr gekoop .Sal maar moet sien of hy gaan werk.
Gaan daar n groot verskil in die node spoed wees met die 55gr?

About 45 fps faster at the top pressure node with the 55 grainer ) if the burn rate stays the same

My 24 duim geweer se node met 55gr koele is by 3250vs. Dit is egter soortgelyk vir die 22 duim lope.

But pressure comes down about 5000 psi

Correctimo. Druk 50K met 24, 55 met 22 en 60 met 20 duim lope.
