Re: Anyone have a good subsonic load for 308 Win?
Can’t vouch for this data personally, but (because I have a couple of old boxes of Sako 185 subsonic) I made a note of this from an article I once read:
Sako Subsonic factory load: 185gr bullet, 9.0gr Viht N320, RWS magnum primer.
(requires 18” barrel and 1:10 twist).
In expansion tests trying to replicate this load for a conventional 308 barrel, none of the following expanded at 100yds:
Nosler BT, A- Max, Speer (type unknown) Sierra (ditto) Lapua (ditto) or Barnes X (!!)
…accuracy was also poor.
Winning load for a 24” 1:12 barrel?……
Lapua 200gr B416 loaded backwards (yes, backwards!) with a COL of 2.433” over N320, CCI 250 mag primer –final charge weight not specified- sub MOA and hard hitting due to flat-point (ie the base!).
Hope that may be of some help!
