Articles / Re: Loading Beyond Max Loads

Dutch - Thanks for another great thinking man's article....if you reload you got to copy this and save it....was resizing last night.....

Yes, I do weigh everything, including myself...LOL...including primers, bullets and a file that tells me the neck thickness of each round after each shot...I know that I am crazy to do this....but have the tools and now the time to do this the right way.....

When I get new preferred Lapua, Norma, Nosler brass (and other manufacturers), run them through the size die and check the length and trim them up if necessary! Then I load the round and then head to the range....after firing all 50 rounds and am getting ready to resize them and then check the length and will have to trim every round some....and will check the neck thickness before trimming the brass....they will write it down the thickness and then start trimming......

After the second and third and even the forth firing, the brass has seem to be stretch out to the max but then you have to start worrying about the necks and base getting to thin. My ideal goal is to reload each piece of non-mag brass seven times but some brass just won't let you go seven times....Magnum rounds I normally try to get 5 loads out of it, but normally is only three times! But looking at each piece of brass under the round lighted magnifying glass and if a crack is spotted that brass goes into the recycle bend!!!

The big question is how thin is too thin to seat a bullet and make sure it will stay where you have put it in the case!! Back in the early days, I have several pills/bullets that have been seated at one depth and when I reached in to get them to load up the rifle you can tell that the seating depth has changed, some how the bullets have seated deeper into the casing!!! But too thin your pills will not seat probably and the neck tension will be erratic around the bullet.....so you have to measure the necks when you reload....and do each piece!!! especially on the third and forth loading....

The method I use is to put a label on each the plastic 50 round ammo box on the outside of the box with the numbers 1 thru 7 on it. I will cross through the number after each time the brass has been measured and sized...may have only 45 of the 50 left in there due to cracks and dings or just lost brass.....

Going back to the beginning and saying that I weigh everything...here is a story and it results target attached that I would like to share.....When I got my second Cooper Rifle Varmint 308, 24" barrel, Swaro AV 3-10X scope, it was a used 308 and had 400 rounds already down the barrel of it (the original owner told me it had about that number of rounds down it)...so after tearing the rifle completely apart and checking to make sure it was what they said it was, I got my Hawkeye Borescope out and clean the barrel and looked down the barrel, clean some more...etc....next I loaded up 10 rounds, taking 10 rounds of weigh the same or close within a grain or two of each round....had Lapua, CCI primers, 168 gn Berger VLD..... 45.14 grains of Varget powder....the astounding thing about it that after assembling the round between all ten of them there were only less than .75 grains difference in the 10 rounds......head to the range and shot the first three into the bank for fouling shots.....then I did a group a 100 yard see target 005 attached (shots 4,5,6).....took the rifle home and did move the cross hairs down to about an inch high at 100 yards.......so the following week went back to the range and fired shots (7,8,9) as shown on target 006.....The 10th and final round went through a deer neck see attached pictured.....

I have an Excel workbook for ILD. There are 3 spreadsheets: Load Data, Target, Box Label

If you would like a copy send me a PM with your email address and I'll send it to you.

Dutch - More good info from you...sort of glad your knee is bummed up a bit, because it gives you time to post and go into some pretty deep subjects....I don't shoot the number of rounds that you and PA and a few others on here do....I do keep a round count down each barrel. I am more interested in accuracy and you do mention that the 55 gn in the 223 has a longer barrel life than the 77 grain 223.......I shoot anywhere between 69 and 77 grains, depending on the AR and the barrel twist

I remember the PA post about barrel life and it was only 5 seconds....that took me back but if you think about it, it is true.....never thought of it that way....

Chromemoly versus Stainless, have heard that about Stainless....what you state is true if you think about it....

Thanks again..... 

Just looked at my round count down my rifles...have one (Win Model 70 in 270) that has over 500 rounds down it and have others several 308's that has over 400 rounds down the barrel and one 7mm-08 that has almost 300 rounds down the barrel....most of my rifles have between 100 and 200 rounds down the pipe....so don't have to worry about me shooting out any barrels in my life time......

Paul, I have examined worn out minigun barrels, and the area just ahead of the chamber looked as if someone had ripped the rifling off, and the grooves  looked like 60 grit sandpaper.  OTH, these barrels had 60-70k rounds fired through them.

First question about brass thickness change as you fire the case. Brass will all flow (stretch) as it is used. Thinner brass will not consequently have as longer lifespan as thicker. Mostly because of the metallurgy of the brass. When cases are formed they are extruded. The pliability of the alloy determines how thick the walls will turn out. The brass as I said flows towards the muzzle, this is why you must continuously check the trim length. Every now and again you must bump the shoulder back.

Which brings us to your second question. I fireform all of my new brass. Then neck size only until the shoulders need to be bumped back by full length sizing. I once full length sized I fireform again. Which then brings up another operation; annealing. Annealing brings the spring back to work hardened brass.

My Bro Bo and I always weight EVERYTHING! Sort into groups of a +/- parameter. So yes you should always determine your baseline.

I have never seen a charge weight comparison for different brass makers.
