Here is a good reason when reloading to be careful.
Thinking of reloading,
- Thread starter Tikkat1x
- Start date
just a quick question about brass if i may,
so after shooting new Hornady brass and then trimming it down to 1.750" and reloading it,
this time after decaping and resizing it, its mostly all gone below 1.750" not buy much as most was around 1.745-6",
i thought it expanded after firing, and what are acceptable tolerances with brass lengths,
thanks.

If your dies were set with virgin brass, then you'll need to reset them once the brass has been fired in YOUR rifle. When resizing brass, you need to resize it to YOUR rifle's chamber (not the virgin brass dimensions). You should only be resizing the brass enough, to push the shoulder back enough, to have consistent, resistance free chambering.
It sounds like you trimmed your brass after firing, and after resizing it set for virgin brass (virgin brass usually has a very generous set back on the shoulder to ensure functioning in all rifles chambered in that cartridge). So, you pushed the shoulder (slightly) too far back, so that when you fired the case again (after trimming), the shoulder pushed forward, filling your chamber, and as a result, the neck was pulled back, thereby giving the appearance of a shorter case (which it is). Think of it as a pressure wave, that irons the case out against the chamber walls, from rear to front. If there is space between the shoulder of the brass and the chamber shoulder wall, when it (the brass) gets ironed out against the chamber wall, the brass forward gets drawn back to fill in the void, which makes the neck shorter. When you then FL resize it, the opposite happens. You squeeze the case down, from front to rear, so pressure then squirts/flows the brass up into the neck, making it longer.
If the cases functioned fine, then don't worry too much about the neck being slightly shorter. Instead, focus on only bumping the shoulder back the small amount needed to ensure reliable chambering. Eventually the case with grow over successive firings. The goal here however, is to limit that amount of growth to the least amount as possible per firing. By just bumping the shoulder back as little as possible, you're limiting how much the case grows when it expands to fill the chamber, and you then push the shoulder back a little (causing the brass to flow forward), making the neck slightly longer each time. By limiting how much the shoulder is moved back and forth between firing and resizing, you ensure long case life, by not excessively working the brass.
Clear as mud?

If you are getting good groups and it's meeting your expectations then sete on it . Your previous post 5-10mm sounds fine.
ADI brass is essentially a military brass so it is marginally thicker , hence heavier and will weigh a tad more.
That's not a problem but it just means the internal volume or water capacity is slightly less so changing brass will get a slightly different result.
If you assembled these measuring base to ogive it just means you know the measurements. The case probably hasn't had to much influence on the external dimensions if the dies are the same.
There are tons of variables and some trial and error.
Ex military brass and ADI cases are sometimes easy to source and tough enough for numerous loads.
Buying a premium brand is more expensive and everyone has a preference, some may may not get more reloads but then that is all relative to hot loads, annealing, resizing and maybe other factors.
right chaps, i started off not wanting these things because i told myself i didnt need them, now i just want them so thought F*&k im going to buy them,
No 1, case tumbles, decided on the FA wet tumbler,
No 2, electronic powder dispenser, seen a few from the usual makes but wondered what you guys recommend, doesnt have to be the best in the world, but something that works well.
No 3, electric case trimmer station, saw a video of a bloke using a Frankfort Arsenal one and thought id have a bit of that, but recommendation on them to please.
recon they will all make the prosses easier for me, i read a while ago a bloke saing he could reload 100 rounds in 1 hour, im currently at 20 in 2 hours, thats wire wooling them to, i prefer them clean for case inspection, and now i like to take my time, check im doing everything right every step of the way, time matters not one jot.

funny you should say that as i really dont mind the beam scale iv got, and once its set right for the charge weight im using then its only a couple of twists of the trickler and its done,
and i actually enjoy doing that
the RSBC trimmer iv got is a rite little t&^t though, nearly rips my finger nails off every time i use it because of the awkward way you have to hold the handle when trimming,

Is that standard practice when you start rolling your own?
Nothing at all wrong with powered trimmers, mine is Hornady, I had a Pact Powder dispenser/scale, the dispenser quit me for the second time however the scale works. You can produce very good ammo with the tools you have.I know. I thought I’d make do with the perfectly good stuff I had. Now that’s all changed. I’m all in
