300 Scenar actual diameter (mic'd)

[jonaddis84]

Wondered if someone could mic me up the actual OD of a 300gn .338 Scenar.

Trying to get the right size bushing, and my supplier is out of stock of the scenars right now.

Thanks

A buddy of mine shoots them, he said they mic'd out at 0.3376-0.3378 across 20 of them.

No idea what lot number that was.

<span style="text-decoration: line-through">Wow, I wasnt expecting that large of a range</span>. Also wasnt expecting that small since some sites list them as "338 caliber (.339 diameter)".

Looks like I need to try to trade off my 365 RCBS coated bushing to someone...

Edit: Nevermind, read those diameters wrong, I thought I saw a .001" difference, my bad

That large of a range? .0002"? thats 2 units out of 10,000. Thats a pretty darn small variation.

If I'm not mistaken, the tolerances on match rifle barrels are about that amount...

I read it wrong, at first glance I thought I saw .3366-.3378

Just be aware that Lapua and other European bullet manufactures, like to, at times go up .001" in their bullet diameter, because they feel that the over-sized bullet makes a better gas seal in the bore.

I have some 185gr rebated boat tail D-46 bullets that are marked .309 on the box.
