Does anyone have schematics showing all the dimensions for a 300 RUM?

Perhaps one that was in a magazine or one of the new manuals.

If so, can you scan it and send it to me?

I want to make a reamer for a 338-300 RUM with 45� shoulders and minimal taper.

I've based one on a 338 Jamison (believe it or not) and it almost holds the same powder volume as the 338 Lapua.

I can't come close to the 338 A-Square or the 338 Excaliber for powder volume. So this is the closest that I can get.

Please help.

Thanx

Contact any of the reamer makers and they will send you a print of the specs.

PAw, I'm reading these specs from the Barnes #3 manual, so you might want to re-check them. Anyway, OAL-2.850", length to shoulder-2.3873", length to bottom of neck-2.544",base-0.534", outside neck diameter-0.344", 30 degree shoulder. Hope this helps. - Dan

Gents,

Thanx for the tips and the info.

Interesting, www.calweb.com/~haas/ammoguide/
shows 2.850 OL, 2.390 to shoulder, 2.580 to neck with the neck OL being .270.

I'm trying to develop a wildcat based on a combo of the 300 RUM and the 338 RUM.

What I have is a case that has a .532 rim, a body above the rim at .550 - .5385 at the shoulder, 2.493 to the shoulder, a 45� shoulder, 2.58 to the neck and 2.850 COL.

Hmmmm . . . . guess I better get a book and get this straightened out.

Thanx again.
