Dagse,
Watter van die volgende kruit:
Reloader 19
N550
H4831sc
Imr 4350
Sal die beste geskik wees vir 140eldm in 24” loop. Die 140 se tpl sal hier rondom 74 mm wees en sal n cci200 primer gebruik.
By voorbaart dankie
Groete Adriaan

Reloder 17
Viht N550
IMR 4350
In that order
Reloder 19 and
H4831SC are too slow burning.

Something not right here.
Your burn rate is way too high.
you about 120 fps above where you should be.

Met Dale se opmerking in gedagte. Waarmee is spoed gemeet?

Oom 3-Poot,
Dit is met labradar gemeet.
Ekt 2-3maande terug n ladder geskiet. Ek self kon nie veel daar in sien nie want ek self weet nie altyd waar na om tekyk nie. Ek sal kyk of ek daardie data hier kan plaas dan kan mens vergelyk

As things stand now your load is 63116 psi
SAAMI max is 60191 psi

Very possible
Make your TPL 0.6mm shorter and shoot 40.5 grains
Lets see where you at and re-assess.

Ek maak so, dan laat weet ek.
Hopenlik is dit die probleem.
Dankie Dale,

If you really want max speed and don't mind a slightly compressed load then try Reloder 26.

Dale,
Wat sal die spoed wees met n550 en reloader 26?

Reloder 26 PREDICTION for Node 5 is
2890 fps at 56300 psi
3 to 4% compressed load

Your burn rate has come down quite a lot
Nearest node is 40.1 grain
2675 fps Average on the Labradar
51838 psi
Node 5 is potentially
42.0 grains for 2785 fps
59353 psi
I don't know if your burn rate is going to increase substantially with the higher pressure so you will have to approach this node with caution

Hallo Dale,

Hallo Dale,
Ek kon die boonste ladings gaan skiet en het die volgende ondervind.
41.6-2775,2769,2790 en 2776
41.8-2784,2780,2755 en 2745
42-2791, 2796,2795 en 2807
42.2-2807,2814,2814 en 2815
Ek sal kyk of ek fotos kan plaas van groepe. Dis op 300m geskiet. Ek sit eintlik met n dilema hier want een groep lyk mooi maar Es is nie klein nie en en ander groep is groeter maar ES is laag.
Ek hoor graag julle insette?!

Your node is predicted to be at 41.7 grains and 59674 psi
The other loads are over max pressure.
If the best group does not have the lowest ES then don't worry about it,
Let the grouping be the deciding factor
