    What's wrong with drivind a .440" slug down the barrel amd measuring the slug? This has worked for me for nearly all my firearms (except most 22 rimfires and my AK). . Then what? Shoot them?

    For me, that would be a lot more trouble than driving a slug doen the barrel. I have slugged nearly all my guns, no big deal and it only needs to be done one time (I normall drive 3 or 4 slugs to get more than one measurement). Lead balls, soft cast...

    A very minor "hint" of oil in a new mold will produce wrinkled bullets. Most of the time I will soak a new mold in clean mineral spirits andsquirt with cholorinated brake clean. I'd have to see a checked bullet and watch you apply one before I...

    Shoot 'em! A couple wrinkles as explained above, but otherwise lookin' good. I started with a single cavity mold for my 44 Magnums and the old saw, practice, practice, practice is the key. It's often said the only way to learn to cast bullets is to...

    Thread drift is inevitable, a fact of life. I cruise several different forums of different themes and all experience thread drift. Very few threads stick to the OP question/statement passed 4 or 5 replies...

    I disagree with the status symbol claim. I don't share my equipment or guns with anyone. Nobody knows my arsenal contents, nobody knows my equipment inventory. I purchase things for my needs/wants (why would anyone, who is not a specific collector...

    I don't have much of an opinion about equipment costs. I drive a Tacoma that cost me about $25,000.00 new and my buddy drives a Ford with everything included that ran roughly $70,000.00 and we both get to the range on time successfully. When I was...

    Well, case cleaning is probably the most talked about (in forums), but the least important part of reloading. Many, many posts about whose "additive formula" or method is best and some include 4 or 5 items. New reloaders are lead to believe pristine...

    I have a couple drums I made from 1 gal plastic jars. I glued a couple pieces of wood molding to the ID for agitators. I'm not familiar with the RCBS tumbler, but it shouldn't be too much trouble attaching the drive pulley... Perhaps, but I...

    I might melt a bunch together and check hardness. Pencils and Lee tester are inexpensive methods and for now you don't need a +/- 1 BHN accuracy in testing. I have my "Mystery Metal" that runs around 11 BHN but I have no idea of the composition of...

    Shooting cast bullets I add lube and sized diameter. When shooting out doors I occasionally add weather conditions (temp, sunny-overcast, rain/mist, etc.). I also add my "condition" (I have "bad eye" days and "blah" days when accuracy is greatly...

    FWIW; 50-50, pure-wheel weight is what I used early in my casting to stretch my alloy. I had access to wheel weights through my job and pure was easy to find. With a decent lube and proper fit I could push my 429421 to roughly 1,200 fps in three...

    I do much the same as Mr. LaRouche. A couple of my 44 cal molds drop a bit over .434" and with PCing sometimes they can get tiresome pushing them down to .431"... If you are sizing down a "lot" and the sizing gets "difficult" the there's no...

    A Lyman Cast Bullet Handbook would help a lot (I prefer the 3rd Edition, but the 4th will do). Like Rcmaveric, I just use BHN as I just air cool all my cast boolits, no need for chemicals for water drop or heat treating. I have been casting for a...

    Lee offers "popular nominal" sizes for their sizing dies, and 38/357s "normally" use .357". I have customized, honed/polished the ID of about 6 Lee sizing dies for specific cylinder throats and barrels. No big deal and easy...

    I would consider the .3575" the groove diameter, and the .351" the bore diameter. Terminology may be a bit confusing at times. Bore diameter is the diameter of the barrel before rifling is cut (formed, etc.). The groove diameter is the diameter of...

    Max loads listed in any manuals are SAAMI pressure related (newer manuals/tested loads are tested with much more accurate equipment than older tests and some are much more accurate than the copper crush method). The tech tech/labs used their...

    No offense intended nor trying to be snarky, but what's the purpose of your badmouthing Lee Universal Decapping dies? Are you "warning" us ignert reloaders of Lee's "junk"? (FWIW; I have been buying Lee dies since '77 and have had only one problem,...
