A few reloading questions
 
Working on my first batch of reloads, which happens to be about 500ish rounds of 223's I've gathered over the past year of so. I'm waiting for a good digital scale before finishing up. That should be here an a few days.

I took apart another 223 round to measure the length of stuff. I got 44.45mm on finished case length. What's the +/- value on case length? What is too long and what is too short???

Also...

I put a few rounds together with no powder to see how stuff worked and what it did. I found that I crimp it so the bullet has a little bit of slop and if I adjust it and/or press harder to crimp a little more it sinks the neck down on it self and pings out a big ring right where the neck draws in. It's like the top of the case is getting pressed too hard and squashing.
So what's the trick on getting the bullet held into place tight without jacking up the case???

Don't load 500 rnds for a first batch load maybe 5 or 10 if something is wrong with your load powder crimp overall length not seated properly you will have a big mess on your hands

I was planning on about 5 or 6 loads at different grains to see what works best in the hand full of different rifles, then doing the rest with what works best.

So what's the +/- range on case lengths?

You are right with bottle neck rifle loads like .223. Pistol loads are much more forgiving. Only load a few and test before loading large quantities.

Check your reloader's manual. (OH, get one...)

You'll see a few specs listed at each caliber,

Most notable is COL or COAL, which is "Cartridge

Overall Length- size with bullet seated.

Then there's "Maximum case length"- The maximum allowance for

a case to stretch.

Then there's "Case trim length"- which is usually .010

(as in, 10 THOUSANDS of an INCH) shorter than Maximum case

length.

Now, all my manuals list this info in thousands of an inch, but

suit yourself. I'd be awfully careful, and follow directions very

closely.

ill try and answer some basics.

first get a reloading manual it will have all the answers as to correct case sizes. you should use the dimensions listed in the manual your using powder weights and seating depths from. while there are standard sizes for a given caliber, you will be much safer if your not exceeding the information given in the manual your using. while its ok to go slightly under max case length its extremely dangerous to exceed max case length. it is also very very dangerous to exceed maximum seating depth without special tools to measure the exact throat length of a given firearm.

do not re-use powders from commercial cases.

do not use charge weights based off salvaged powders from commercial cartridges

when you pull a bullet from a loaded case you cannot reseat it without at least resizing the neck of the case that is why your having bad results reseating.

Pulled the bullet to see the length of the case, weight of the bullet, and weight of the powder to get a starting point with a starting base line. Then I through everything away. Never tried to reuse any of it. Previously shot cases but new Hornady 55 gr bullet.

And I have purchased a few reloading manuals. Nothing shows a maximum or a minimum case length on anything.

My lee reloading manual show OACL ( over all case length) min and Max.

What reloading manuals?

THEY ALL provide this data...
