More manne.
6.5x55 1-8TWIST 28"
Sal waardeer as die QL gurus vir my kan kyk wat die node spoed sal wees met 140 gr eldm en 28'' loop en verstekwardes vir n560.

Die 28 duim loop los jou tussen 2 nodes.
Ek het 'n 30 duim loop ook beloer

Dankie Marius
2950FPS Teen 55000psi klink goed ,kan korter loop ook daar uitkom sonder om oor max druk te gaan.

Onthou net dat dit die tussennode is en hopelik is hy in daardie omgewing.

Dit is die looplengte waarop ek ook besluit het vir my 6.5x55Ackley, 28duim. Heel paar manne wat hom met 140gr pitte teen 2940fps akkuraat skiet skiet

Die ackley is die game-changer ek wil nou weer std gaan. Sal die AI se nodes meer geskik wees vir 28"

DD dit lyk soos 61900psi. Ek neem aan die 15 voete vir chrony is reeds by jou spoed.
Laat die slim manne net bevestig.

61800 psi !!!!
Why is your TPL so short ?
Re: 6.5x55 loop lengte

You got a long jump down to Node 5
+- 2900 fps

HI Dale the tpl is short not to impinge on the lands, the chamber is also tight (dull rental reamer). Are things going to change once fireformed brass is used and where are the half nodes that everybody's talking about?

I'm not sure I understand about your short tpl.
Did you deliberately cut the chamber with a short throat ?
You should be able to get the 140 grain ELDM to about 79 or 80.0mm with a standard 6.5 x55 chamber.

I also expected a tpl of 80 mm the same as my previous chamber .The reamer used must have a short throat.

Strange,
That's not normal.
I have not had time to convince myself that the half node theory works but if you want to try it, it should be around 2980 - 3000 fps
Pressure will be around 56 to 57000 psi
Your primer pockets may still grow prematurely.
PS I would ask the gunsmith to lengthen the throat.

Got up to 20 reloads on my previous brass.The short throat was a surprise, does have the benefit that rounds fit in mdt magazine and looks from the first few shots fired that the rifle wants to shoot.

Het nou die eerste 100 doppe in die nuwe kamer geskiet ,sien nou die koels wil nie in die gevuurde nekke ingaan nie . Dit beteken ek sal 0.1mm van die nekke moet afdraai.Ek wonder hoe die feit dat die koeels nie met .05mm per kant kon release nie ,die QL berekeninge sou beinvloed.
Ek moet laai vir n komp en daar is nie nou tyd vir lading ontwikeling nie moet ek mik vir 2900fps op magneto.

Diesel, naand. Waar staan jy met die dies? Ek soek steeds. My eeste kamer was n mislukking. My loop is nou net so n rapsie oor die 27duim. Ek het net so n kort keel. My tpl is rondom 73.4mm. Kan nog nie rerig se of doe roer gaan skiet nie. Wil tog so lyk. Het laasweek n 3skoot groep met IMR4350 geskiet van onder 10mm
