reloading

[heritage 202]

Hi all, please forgive my ignorance on the subject of reloading as ive only recently started to take an intrest,I have a question that i just cant find a logical answer to..... i am an engineer and the company i work for has most of the usual machinery youd come to expect. we have over the past few years (20 ish) replaced all the DROs and other machine controllers with more modern versions. heres the question.... why is almost all the information thats available for reloaders is still in imperial ect...? hasent anyone ever revised the info and produced a more modern metric version ? considering metric has been taught in schools for such a long time and has become "universal" as far as measurements are concerned would it be worth revising ? i look forward to your replys,atb

Quick and easy answer is, most reloading info comes out of the USA, second answer is, would you rather work in grams or grains, for instance to load up a 155 grain lapua scenar with a minimum load of N140 would be 2.38 grams or 36.7 grains, for a maximum load on N140 you need 2.81 grams or 43.4 grains of powder, I KNOW WHICH MEASUREMENT I WOULD RATHER BE ONE UNIT OUT IN, :weight_lift2: when the odd grain of powder can make a difference on chamber pressure :oops: I sure don't want to make a mistake of 1 gram, that is for sure,

What I was going to say. The Americans have been much slower to adopt metric measurements. They still define their calibres in Imperial. One of their Mars landers went in without braking because someone had calibrated the altimeter in feet rather than meters. Ouch.

It was in fact a European lander, Beagle II, and the reason for the splat moment was that it was calibrated in MM, not a sensible measurement, if metric was better for reloading then people would be using it, as it is i know people in Europe who reload and even they don't use Grams as a viable measurement for handling powder, You can reload in grams if you like, just please put up a big sign saying so before you shoot any of it, so the rest of us can stand well back.

 

Beagle II also had only a 7% chance of making it down in one piece even if it did have a perfect decent, if the airbag system impacted a rock of 30cm in diameter on touch down, the chance of it surviving was ZERO, I used to work as a contractor for the ESA on Flexible Orbital Structures, because in this day and age, the Marine industry is far more advanced than the space industry and they wanted some common sense input into their projects, it didnt work, far to much politics and protectionism of projects that hadn't a chance of working. Glad I am out of it and back with the marine industry and DESIGNING GUNS

Hey, we only just dropped all the Latin terminology! Stop picking on us we are a minority group....funny handshake.... back to turning lead in to gold

Dont worry, i wont be causing any explosions as I DONT RELOAD, its a subject ive only just got intrested in.i was reading the usual info and watching a few youtube clips when i noticed no one seems to have adopted a metric system. i wasent really thinking powders with the measurement issue but more along the lines of case prep.i hope to start reloading and i just thought id do a little re-search on the subject. thanks for the replys

[heritage 202]

Sorry,i forgot to ask...id like to get a reloading manual, just to do a little reading up on the subject,ive seen theres several available,lee,speer ect... what would be the best one to purchase for a novice ? is there one that is superior to the others ? do you have any reccomendations? thanks again

You obviously know a hell of lot more than I do about this. I thought, though, that the problem arose because the Beagle was designed at Leicester University and built in Britain and Europe, while the delivery system was NASA built and there was a conflict between the Beagle's metric calibration and the delivery vehicle's Imperial measurement.

I would also like to mention that one of my first jobs was in chemical engineering research. I had to use scales accurate to 0.001 gm. Can you match that level of accuracy on your loading bench? In fact it makes not a blind bit of difference which system you use so long as you use it consistently and if you have to convert from another system make very very very . . . sure you have got the conversion right. The fact is that as said, the Americans stick with Imperial so the safest option is to do the same.

Great to see some intelligent banter on this forum.... if you go on the dog forums half of them can't even spell the word 'banter' lol!

what does banter mean? dont think that word is used on thedog forums,is it just for the self proclaimed experts on the rifle section

You also find their grasp of grammar is also difficult to understand ie 'thedog' should actually be spelt 'the dog'

It's bleedin' obvious mate. A hunter is someone who goes hunting. A banter is someone who goes banting. DON'T ARSK ME what a cunter does, or'right?

Agreed entirely. Grains is a far better unit of measurement for reloading and, yes, most of the info is in imperial because it originates from the US. All the European stuff tends to be in metric though; I have the Vihtavouri manual and it's got both.

Though banter was those itsy bitsy chicken things whose eggs taste really good, but with the attitude like a T Rex, or are those bantams, never can remember
