arrowhead weight...
« on: July 19, 2009, 01:35:44 pm »
what is this "grains" measurement?  how does it relate to normal talk? 

I've got a bunch of arrowheads outlined on a thin skilsaw blade, and i guess they'll all weigh the same amount, making my arrows matched, but...where do you get a scale that measures in grains?

 You can get a real cheap one from 3Rivers.

Most of your archery supply stores sell a hand held scale. You may be able to find a digital scale from a reloading supply store also. Grains is just a smaller measurement used for points and bullets. I am not sure how it converts to ounces or grams.

Correct me if I'm wrong but I think the term "grain" is used in reference to an ancient equivalance that related weight to grains of rice. Am I right?

Scott,

Grain weight is a common measurement used in ammo manufacturing. 1 grain is 1/7000th of a pound. It is derived from a single grain of barley. It's part of the English weights & measures system. It has carried over into archery for arrow head weight. Bullets are designated in grains, as well as powder measures. Arrow heads usually vary in weight from 70-180 grains, with 125 grains as a "standard."
You can purchase a decent small grain/gram/oz scale for cheap. I bought one on ebay for about $30, from a reloading supplier.

It really isn't practical to use a scale that needs conversion. You just cannot get real accurate unless your scale measures in grains. I suggest finding a rifle reloading scale. You can find cheap or expensive. You can get them at Bass Pro's, Cabellas, Sportsman's Warehouse or about any other respectable gun store.  It works great for matching shafts by physical weight also.  ;)

The scale I purchased will read ounces, grams or grains by changing mode. No conversion necessary. Very handy.

I have the same little handheld one from 3Rivers that Eddie mentioned-it works plenty good enough for my purposes of matching shafts, heads, etc.

Actually grains refers more so to grains of barley and dates back to roman times......... the english system was more based on the wheat grain which is roughly 1 1/3 of a grain of barley......
