This has been an excellent read. I am relatively new to reloading, and brand new to this site. Great advice folks!
One topic I haven't seen be addressed yet in this thread is the question of how many times can you "safely" reload your brass. Are there any good rules of thumb on this?
I reload for 22 hornet, 222/223 rem, 204 ruger, 243 win. So what does everyone think - 10 times for the hornet, 5 for 222/223 class calibers, and maybe just 3 for other speedier (magnum type) rounds?
When I first began to research reloading, I decided I would:
1) buy factory ammo first for each new rifle
2) neck size only then
3) and invest in some better quality seater dies
So I get a Lee Deluxe Die kit which gives me a full length sizing option as well as a collet neck sizer die, plus a shell holder that you always need anyway. But then I like seater dies with a micrometer so that I can get my COL's really precise and minimize bullet runout.
In buying factory ammo initially, I build up a supply of perfectly fire formed brass, determine what type of bullets my gun prefers, get some idea about acceptable COL maximums (without pushing this 'seat to the lands' idea and getting myself into trouble with potentially huge pressure spikes).
I don't crimp, and I do neck size like I say - so both of these should help improve my case life. But I am looking for a good rule of thumb on when I should destroy reused brass... not push it to reload them "one more time" that ends up messing me up then.
In my first two years at this most enjoyable hobby I do have one incident to report which I have never fully been able to explain, so I will throw it out here now for everyone's consideration and comment and maybe this will generate some other ideas on "best practices" for all to benefit from.
First let me say that I did catch myself once putting Rem 6 1/2 primers (for my hornet) into my 222 rem casings (that should have been getting Rem 7 1/2 BR primers instead!), so it is definitely key to keep stuff separated. It is also key I believe to not be distracted as several others have mentioned, and to "divide and conquer" - break your steps down into whatever is a manageable block of time for you personally based on everything else you may have going on. So for example I'll clean my brass one day, deprime and neck size another, debur and chamfer the next sitting, measure and sort another, then prime everything the next chance I get, then charge & seat, etc. But on this one occasion I was reloading a charge that I had developed back in winter time for my 222 rem.
So a winter time 'max load' charge (that was VERY accurate) that...
Shot fine all throughout the winter.
Shot fine in Spring and early Summer.
Shot fine in later Summer then again also.
But on one shot while in the field - on a hot/humid day, a casing actually expanded against my bolt face and would not eject. Needless to say, my hunt ended early!
There are so many variables in this business. Was it truly a 'max load' issue? The local gunsmith fired more of my handloads just fine after replacing my ejector. Was it the heat of that particular day? Would a 6 1/2 where a 7 1/2 belonged have done this to me? Defective primer perhaps? Loose primer pocket maybe? Flash hole that wasn't completely clean when I reprimed? I did notice that the bolt was a little tight on that particular round when I went to chamber it up - so could my case length have been suspect?, or would a shoulder not have been bumped back properly due to neck sizing only?
I use a Rockchucker press, an RCBS digital caliper, a 5-0-5 scale where every charge is weighed to being as close to perfection as I can get them. So I feel my equipment is more than adequate.
The smith did say that on occasion you can get a powder buildup on these smaller calibers that doesn't get cleaned out when using a bore guide (as I do before every load development session) where the guide of course takes you right up to the chamber and doesn't help you clean around the outside walls of the chamber. Does that make any sense to you all?
Anyway, this little "situation" still haunts me to this day and although the varmint I was aiming at died that afternoon (the desired result) - and I didn't get hurt, and was only set back a little $$ in the big picture of things, well... the worst part of it all is not knowing what exactly I did wrong. Was it a casing that had simply been reloaded too many times? How do you know how many times is too many times??
