308 Winchester Hornady SST's

[cnoteleo]

I bought some 180 grain .308 Hornady SST's, according to the Lee reloading book when I seat the bullet to the cannelure, it is way shorter than the Min OAL. Are these not made for use in a .308 Winchester cartridge?

What is the item number on the box. I will look up the info in my Hornady book if you want.

Varget - That is weird because the lee book says min oal of 2.800????

Varget is a great choice. The following is the charges listed with Varget with fps per Hornady. Of course, use at your own risk!

308 Winchester
Hornady SST 180 Grain #30702
Federal 210 Primer
Hornady/Frontier Case
2.005" Case trim length
2.740" O.A.L
Varget Powder:

32.0 2000fps (MIN)

34.3 2100fps

36.5 2200fps

38.7 2300fps

41.0 2400fps

43.2 2500fps (MAX)

Hope this helps. This info is directly from the Hornady manual. Take care.

max overall length for the .308 has always been 2.8" that might be a misprint.

I often seat SST bullets out further than the cannelure would otherwise indicate I should.

Don't sweat the cannelure location unless you are planning to apply a slight crimp.

What is your brass length?

COAL of 2.80" for the 308, 7.62x51 is to insure the round will fit in the mag of the M-14 M1a.

I have loaded lots of the SSTs in 150g and 180. I shoot them out of an AR10 so they are seated to exactly 2.8 which is usually the cannelure. For the 180's I use CCI 200 primers in Lake City cases with either 42g Varger, 43g RE15, 46g of CFE or my new favorite 43g of XBR8208. All shoot well with no pressure signs.
