Pre-wieghted Test Tubes (Vials)

[coues7]

Does anyone know what size test tube (vial) to get that will hold 75-100 grains of powder? I think I'd like to pre-weigh a bunch of charges and have them on hand.....with 3 little ones running around the house I don't get to many breaks where I can really concentrate.

A side by side comparison with a 338 Lapua Mag case says a 10 ml will work to fill that case. The outside dimensions are 5/8" OD X 4" long with a radius bottom. Of course comparing weight to volume is kind of like apples and oranges. But that might get you in the ball park. If in doubt just get a bigger size.

Good luck.

I assume if the 10ml would work for the Lapua it would be perfect for 300WM and below. Thanks Victor N TN.

Do you know which ones to get off ebay? I don't want the coagg stuff in them.

I order mine from a labratory supply. But there are cheaper places to get them. Bill at this site: http://www.benchrest.com/asa/ used keep them in stock. But I'm not sure what size he may have in stock. But he owns a pharmacy. He can probably get you what you want.
