Sal een van die QL manne vir my loer as julle kans kry asb?

243 AI
Loop 599mm
VV N550
41gr gem van 3184 fps met magnetospeed
Lapua dop 55.4gn H2O
70gr nosler BT varmint
Tpl 67.75mm

[alecjohnson]

#4 @ 3413fps ongeveer 44gr
#5 @ 3155fps ongeveer 40.6gr

Wil net hoor omdat dopvolume laag voel is dit gevuurvormde doppe? standaard 243 was by my altyd so 53-55gr afhangende van fabrikaat, my AI lapua doppe is almal bo 57gr dop volume.

Groete

Thanks Alec, waardeer jou hulp.

Dit was gevuurde doppe en ek is 0.3mm in die lands gejam

[Dale SH]

Malan.
Did you fireform your cases with this 41.0 grain load ?

[Malan123]

Hi Dale. Yes fireformed 5 cases today with the 41gr load to get the needed data for QL

[Dale SH]

The reason im asking is that based on your current H20 capacity and the fact that your 41.0 grain load is only just on 40 000 psi, I suspect that your cases are not fully fire formed yet.
I would load those same cases with the 44.0 grain load as per Alec's suggestion (+- 49000 psi) and re-measure your H20.

[Malan123]

Thanks Dale. I will do that and check if it makes a difference. I was conservative with the 41gr load as I am jamming it in the lands

[Malan123]

On another note - what should the case difference be between standard 243 case and ackley case i.t.o. H2O value?

[Dale SH]

+-54.0 grains standard and 57.0 grains for Ackley

[Malan123]

Thanks

[Malan123]

H2O waarde van doppe is reg. 44gr het my opi kop 3413fps gegee. Dankie manne

[tripodmvr]

En die groep met 44gr?

[Malan123]

Baie mooi gewees Oom driepoot. Met thermal geskiet en raak hom nog gewoond, maar was snyers op 100m

[tripodmvr]

Het jy 'n koue een in die hand? Tjorts op die mooi groep !!!!!

[Malan123]

Ek het inderdaad, dankie Oom . Vir interessantheid siende my druk nog laag is en ek nog redelik spasie in die dop het, wat is die vlg. node en sy drukvlakke?

[tripodmvr]

Dale het moontlik jou berekening gestoor. Kom ons kyk of hy reageer.

[Malan123]

Dankie

[Dale SH]

If your burn rate does not increase with the higher pressure then your next node is at 3579 fps with 46.3 grains at 57351 psi.
I suspect that your BRF will increase slightly and your node is going to be around 45.8 to 45.9 grains for 3575 fps

PS. Alec did the initial calculation and not me.

[Malan123]

Thanks Dale, appreciate it

[Ockert1992]

Malan, gooi daar 'n foto van die roer dat ons sien hoe die finale produk toe uitgekom het.

Bly jy kon hom so vinnig aan die skiet kry.

Groete
Ockert

[Malan123]

Hi Ockert. Ek dink hyt baie mooi uitgekom, dankie vir al jou hulp. Vir dienwat wonder, al die werk is deur Trueworx gedoen deur Geno. Hy skiet baie lekker...

[Gawie(13mm)]

Nee flip!! Dus pornografie van die ergste graad.
....maar bitter mooi.

[Malan123]

Hahaha. Dankie Gawie. Hy het op die ou einde mooi bymekaar gekom
