.308 OAL length questions

Just finished my first batch of .308

Particulars-

Federal Brass
Hornaday 150g Interlock BTSP

41.0g H4895 (Listed as starting load)

Brass was full length sized and trimmed.

Hodgdon and Lee data lists 2.80 as max and min OAL. I seated these bullets with the cannelure completely exposed and came up with an OAL of 2.78.

What gives? Are these loads safe to use or should I pull and start over. They are for a Howa bolt action.

Just double checked my Lyman manual. It lists 2.685 as an OAL for 150g jacketed SP but doesn't have info for H4895.

As long as the bullet is not hitting the rifling when you chamber the round, it should be okay. A little on the long side, but that's a starting load in my manual.

H1500308,

The OAL is not critical, don't sweat it.

Hornady lists that bullet with an OAL of 2.735".
I assume that would be with the cannelure mostly inside the case where it would normally be.

They also list a Starting load load of H-4895 as 37.2 and a Max of 44.0.

If you are going to use generic load data like Lee, or Hodgdon (they don't even list a Hornady 150, only a Nosler) you can't be too upset if the listed OAL is different.

IMHO: If you want to load Hornady bullets, you need to get a Hornady loading manual. They often use a different bullet shape then most others, and they sometimes have a longer bearing surface.
