Case weight.

i started to ask this last night and changed my mind. but what benefit is there from the brass to weigh the same? and how do you adjust it? or do you just sort them into groups based on weight?
 
Advantage = volume uniformity
Benefit = Uniformity (of occupied volume by bullet base / powder)
How to adjust? = by weight segragation - then, it depends on what you choose; Hunting or Precision Shooting?
How to sort them? Depends on what you want. You have to check first what the volume difference is; you will find it really depends on case volume. The bigger the case, the less the difference. Sort them by average cubic centimeter capacity (again, the amount depends on % of case volume difference it makes). Some say 5%, others say it does not matter...
The decision is up to you, depending on application.

cases then are sized the same externally but say weight 3 or 4 more grains, means that material is on the inside, more material = less cas capacity, variations in case capacity = variation in pressure, pressure variationes = loss of accuracy.

if you want to sort, with in a grain should be more then adiquate, unless you are compteing at the highest of levels.

i personally just like to bang gongs at long range and for me, i dont have any thing gained by sorting cases
 
i guess that makes complete sense, isnt lapua brass all identical? can you get 30.06 lapua round and will they chamber into a standard 30.06 gun?
 
It's funny, when I first started reloading I thought guys that separated cases, uniformed the necks, bought expensive dies etc... had to be out of their minds. Now I am that guy :) My reloading room is getting to the point where it is worth more than my guns... The wife thinks I'm nuts.
 
im building an "office" in the basement and turning the upstairs office into a spare bedroom. the wife doesnt know but the "office" will have studs every 8 inches along inside walls and a solid door with a lock on it. also i may keep my gun safe and reloading gear in the "office"

lol

yes you can, and yes it will, but be prepaired to pay a premium for it, iv never priced out 3006 lapua brass, but i would guess in the 1.25-150 per peice range, i know my .338LM stuff was about 3 bucks a pop


edit :quck google, looks to be about $1.10 per peice give or take a few cents
 
mind sharing the link? i looked in google and came up with nothing, just some info on different types of loaded rounds.

i wouldnt mind get 30 or 40 pieces of it and loading it for the days id like to go and shoot some long range stuff just to keep it accurate.
 
I have .308 Lapua brass that weighs between 170 gr to 174 gr. I sort it into 1 gr batches. I know the only way to really sort them is by volume, but who has time for that? The weight difference could be in the case web, wall thinkness or .001" in the diameter of the extractor groove?

For my .223 cases I sort to .5 gr batches.

I think part of the whole process has more to do with the mental mangement part of match shooting. For me is starts here at the loading bench, not on the firing point or on the way to the match. I know that my ammo is the best ammo I can make, and any error on the target is pilot error.

how much of a difference does you poi have between the different brass weights? ive got some powder and bullets on order so im thinking to kill time ill clean a bunch of cases de prime them and weigh them while i wait for my items.

i saw the same prices, i think the 30.06 is per 100 which really isnt that bad of a price considering its 22 bucks for 20 shots of cheap federal ammo, for a bit less you can buy quality brass
 
For hunting purposes, a couple of grains of case weight difference will matter so little that I doubt anyone could tell the difference out past 500 meters.
For 1000 yard competition, I sort in ½ grain [.5] groups.
One needs to pay more attention to case neck uniformity and neck tension for long range consistency.

those are two things i still need to learn to do, all in good time.
 
all good if you have time for it. I cant be bothered.

I found that Weight sorting bullets was enough for me (even though I barely ever do that).

That's the nice thing about reloading, you can really go ape Sh*t on QC if you want.
 
Before weight-sorting new brass, I believe it should all be trimmed and chamfered to identical length......maybe Lapua and some other brass is from the factory, but much isn't......have never weighed the filings from trimming, but if you're sorting to .5 gr, I'll bet its a factor.

That's my next question... Should I sort by weight every-time I shoot them, as I would be shaving material during case prep.

Also if the cases are from different manufacturers but have the same volume, will I still get good results?
