WTK Reloading Data for H335 & 147gr FMJ

[michaelwaynew]

I am looking for reloading data for H335 powder and 147gr FMJ-BT bullets. I have two different reloading manuals and neather has any data for 308 using 147gr bullets.:confused:

According to my handy-dandy Lyman 45th Edition, you can start out at 46.0gr of H335 for 2754fps up to a maximum load of 50.5 gr for 2985fps.
My Speer Number 12 lists H335 starting out at 43.0 gr for 2562fps up to a maximum of47.0gr for 2879 fps.
I don't think anyone lists loads for 147 gr bullets, they all round them up to 150 grains.
As usual, back off your loads and work up to maximum loads cautiously.
It's interesting that the loads from Lyman's book(published in 1970) are so much hotter than the loads in my Speer book, published in June of 1994. Liability concerns, I guess.

Speer 13th edition is the same. Lyman 47th edition starts at 38 max's at 45. The Hodgdon site has a maximum of 44.

Lake City loads them with WC846 at 46 gr. BL-C(2) is the equivalent powder.

Speer max's that powder at 44, Lyman at 49 and Hodgden at 48. So everybody has their own opinion.

I use 46 grains of WC844 or H335 in mil pull down brass, CCI 200 primer, 147g FMJ pull down bullets. Gives me 2700 f/s out of a 20 in AR10 and no high pressure signs
YMMV

Go here (http://www.hodgdon.com/data/rifle/308win.php).
Pretty much all the powder manufacturers, including Hodgdon, offer data for their products viewable from their respective web sites.
Though BL-C(2)™ might be a better choice as it was developed for the 7.62 NATO cartridge, they do list a load for a 150 grain projectile with commercial brass using H335.
Same data would apply to a 147 grain projctile as well.

If your using mlitary brass, reduce the starting load by a factor of 10% and work up from there.
