What is going on here?

So I am still relatively new to reloading. I reloaded some 7mm mag,some 260, and 35 rem. I did some 8mm mauser and am confused. I got Hornady 8x57 brass and 200 grain Nosler Accubond. The Oal says 3.25. But i seated it that long and it looks horrible. Like the bullet is about to fall out. In my Nosler manual, it says their test loads were seaded at 3.030. What am I missing? Also, I did seat one at 3.240 and it was not touching the lands. So if I seat the bullets at 3.030, it has quite a jump to the lands. Plus wont that decrease case volume and increase pressure? I am very confused and need some help!

For what it's worth, here is my rule of thumb for any specification that doesn't pass the "smell test". Look up the same load in a totally different source. There is always the possibility that the source you are using has an error.

Seat it at least one caliber in, or the same OAL as a milsurp round. You can google Unclenick's method for finding optimal seating depth, but for a mauser in 8x57 I doubt the throat is in good enough condition to tell much difference.

Where are you getting the OAL of 3.25 from? If I am reloading Nosler bullets, and the Nosler book says to use a COAL of 3.030, that is where I would start my load development.

Oh I looked again and saw the 3.25 is sammi specs. Is there often such a difference or is that because of the bullet design?

Its because of bullet design. Light bullet is shorter than heavy bullets. SAAMI 2.815" minimum to 3.250" maximum COL. Seat the bullet base (full diameter of the bullet, not boatail) at the neck shoulder junction. See if that gives you a usable COL. http://www.saami.org/PubResources/CC...m%20Mauser.pdf
