308WIn S341 155gr ELD-M's

[Peter OMoore]

Goeie dag ek het hulp nodig met QL Node spoed voorspelling.

NB! Die ladings moet nog geskiet word vir spoed.

Sal deurgee sodra ek kan!

Wil net weet is ek op die regte pad met S341 of moet die ingevoerde kruit VARGET roete gaan?

Ek het 3x blikke S341 (nuutste lot nr. 2019 - 0% verskil) en wil graag weet of dit goed sal werk met komponente hier-onder genoem of moet ek eerder VARGET gebruik?

My vorige rondtes was Baie akkuraat met S335/43.6gr/PMP doppe/150gr SGK/CCI 200 - 2745fps.

Mik vir ±2750fps met ondergenoemde.
NB! gaan die ladings skiet spoed meet en dan deurgee vir julle insae om te werk na die ±2750fps of wat julle aanbeveel?
Met klem is op die Mees Akkurate Lading!

Dankie waardeer. Groete Peter O'Moore

Looking at the data and putting that through QL my advice would be the following :-

1. Shoot without the suppressor until you have the load sorted. Some people claim a speed increase with certain suppressors that will confuse the node calculations.
2. I would make COL = 71mm, meaning that 6mm of bullet shaft is contacting the case neck. Better neck tension.
3. Start with 44gr S341 and go up in 1gr increments till you exceed 2750fps, then stop. That speed is close to a 1/2 node. The initial firing is just to establish burn rate and give data for node calculations. One or 3 shots per load should get us closer to the nodes.
