weight sorting brass

[zx10mike 137]

hi guys in your opinion how important is weight sorting brass and what difference can it make to groups? i had a nice group today with a flyer and noticed my brass varies between 82.6 and 85 grains i do sort for my .204 but i was in the early stages of load development and bieng stupid.would be interested in your thoughts.

There are a lot of things you can do to improve groups but the first thing to do is openly ask yourself how tight a group do you actually need. If you are fox shooting or deer stalking, .1MOA isn't needed and in all practical field situations never achievable.

 

Weight sorting brass isn't as accurate as sorting by internal water capacity, nor will achieve better results than neck turning. Something very easy to do is sort your bass out and mark the think side of the case (small file mark on the case head), load each round with the think side in the same location. Again neck tension, bullet concentricity, weighing each powder load and weighing each bullet. All these things will squeeze a small bit of accuracy. I guess our ultimate goal is to produce clones, each round being exactly the same as the next in terms of weight, dimensions and tolerances. However, the primers will always let you down! I did an experiment a few years ago, using primers to launch bullets and the velocities varied considerably.

 

I have more or less an unlimited supply of once fired brass and in the beginning I used to produce my rounds, sort them in to the same weight and box the rounds up in to batches. In reality, I didn't have enough ammunition allowance to stock stock pile sufficient rounds to make it worth while and I ended up with "odds and sod's".

i consider it a waste of time in a standard factory rifle to be honest, best thing is to check for brass concentricity around the neck and also when the bullet is loaded,

 

throw powder as accurate as possible, and primers should be seated with the same force, etc, neck tension, powder burn rates, wind, humidity, altitude,

 

will all lead to grouping problems, but the best thing you can do is PRACTICE SHOOTING, nothing will shrink your groups more than this one single thing,

 

Snap.

Hello,

I am an engineer by trade and a shooter by choice!

I 'think' that the 'smaller' the case it is more likely that case 'Equality' is going to be an issue worth persuing.

I have 2 centrefires, both hunting rifles, 1. 22.250 Rem and 2. 270 Win, my opinion is that these are both 'big' and therefore

(especially in a 'hunting' round) the case parametrics are diluted by the sheer size and scale of that particular calibre.

However when things 'shrink' so does the 'science' attached to the ballistics, the .204 although it is not in my remit, .223 is

the smallest I have tried, I am certain that attention to detail pays off proportionaly to the reduction in size of the cartridge?

What do you think?
