    Overcooked Brass (Annealing question)

    I wanted a hotter flame, so I switched to a swirl flame head. I find the swirl flame works quite nice as it tends to wrap more around the neck and shoulder area producing pretty consistent results for the whole 360°. I did have to make sure the angle/direction of the flame was pointing a...

    308 FGGM brass

    The 12 firings I've got from my Federal .308 brass using moderate to hot loads is out of a factory bolt action with a premium barrel. I imagine an AR10 platform with looser chambers than typical bolt guns would certainly shorten the life of brass, like Federal that has a bit softer material...

    Seating force

    That's good! The suggestions for running a nylon brush through the necks right after the annealing is a good idea to take out some of that abrasive oxidation layer that annealing leaves behind. I like to clean the necks before sizing so that I'm sure the abrasive oxidation layer doesn't work...

    Seating force

    What is your annealing process? I assume you're flame annealing??? If so, what's your indicator for the right amount of time for the cases being in the fame (how hot the necks get)?

    Why do people load so hot?

    In my .308 pushing 177 SMK's with 46.5 grs H-4895 got those pills to average 2,902 fps, this using neck up 277 Sig Hybrid cases with the cartridge COAL of 2.977" . Estimated PSI at 80k with no bolt lift or extraction issues over 15 shots, which is easy enough to do for modern actions to handle...

    May we do it just because we're Hot Heads. :p

    Overcooked Brass (Annealing question)

    I used to do the orange flame. I found that wasn't really a good indicator. It's the color of the neck glowing that's the better measure. :cool:

    Overcooked Brass (Annealing question)

    I've run tests and actually measured the hardness afterwards too, like so many. . . I'm not guessing about the results of my flame annealing. The necks have got to get to a red glow, as seen in a darkened room. That red glow is an indication that it's got to ~1,100 to ~1,200°F. 650° or 750°F...

    Mixing brass lots, same headstamp.

    Even though it may not matter in terms of getting the best possible outcome, it does matter in reducing the worst possible outcome. :rolleyes: :giggle:

    Groups are to small

    You're loads are not producing the same es/sd's? What kind of differences are you getting? I don't get exactly the same ES's and SD's with the same load either, but they're very close, where I'm just looking for SD's in the mid single digits. Here's a couple of pic I took last year of my...

    Reloading Application to Document the Reloading Process

    I also learned the hard way to back up my computer data often. Back in '88 I was coding a personal app on my Apple Macintosh and had worked real hard for about 3 hours to get what I wanted, then the power went out and I lost all that work and had to start over. I should have back up my work...

    Mixing brass lots, same headstamp.

    Poor SD's and ES's don't produce good results on target, for sure. But the best SD's or ES's seldom produce the best result on target. So, it's true that one needs good SD's/ES's for good groups, but focusing on the best ones won't guarantee you'll get the best groups (removing any affects...

    Mixing brass lots, same headstamp.

    Before I get to 10 shots, I'll do a series of 3 shots each to cull out those the did poorly. They're easy to distinguish from the good. It's the good groups in that series that's not definable due to small sample count. Once I've identified what what looks like good groups than might be...

    Mixing brass lots, same headstamp.

    It really does depend on what level of shooting you're doing. For most shooters, mixing lots of Lapua brass isn't likely going to be able to see any difference (Lapua tending to have small variations from lot to lot than other brands). I've had Lapua brass that had case capacity at 56.2 grs...

    Reloading Application to Document the Reloading Process

    For brass prep, I have my prep steps listed on both sides of an 8x11 piece of paper that I keep with every batch of brass that I have that's in their own container. Loading data and results are kept on a spreadsheet. The spread sheet makes for easy searching and sorting for comparisons...

    Ruger Precision Rifle Discussion

    You're two different head stamps can have very different case volumes. Different case volumes will produce different results in proportion to the difference in volumes. When you measure cases volumes, which should be at least 10 to get a good idea, be sure to do the measuring on fired cases...

    Annealing issue

    If the 1 lb tank is sitting upright next to your Ugly, then there shouldn't be any issue with the liquid propane flowing into your torch head. . . . . . . unless at some point the tank was laying on it side at some time when the hose connected where the liquid ran into the line. With the line...

    Annealing issue

    It's a 1 lb tank? I have my 1 lb tank sitting next to my Annealeez and it works fine too. The there's not enough difference in the level of liquid propane in the tank to be above my torch head where the liquid will siphon off. You simply have to make sure the liquid doesn't siphon into the...

    Annealing issue

    Where's the tank in relationship to the torch head? Sounds like you might have the tank sitting on the counter along with your Ugly??? The tank should be sitting well below the torch head.

    How about 4 barrels at a time? ;) :cool:
