IMR4064 + 150gr FMJBT hornady- Help me with a load!

[GunNewb]

Brewing up my first load this evening folks. I have some basic data in one of my manuals for 308- dont have the hornady book though. Any suggestions on a starting load with these components? Tips appreciated!


CCI #34 primers
150gr FMJBT Hornady
winchester cases
IMR 4064

PS- These are for my norinco m14(thanks!)

I assume these are for your M14 308Win 7.62 NATO. good choice of powder.

Hornady says 38.4-44.9gr max IMR 4064 150-155gr bullets
Speer says for 150gr (inc FMJ) 43-47gr C (comressed) max IMR 4064
Hodgdon the powder maker also has data on their site for IMR I would use the starting loads for a different 150gr 308 Win and work up, they list the 150gr Nosler Ballistic tip at 43-47.7gr C max.

Start with 43 and work up in 0.5gr increments. Say 5 of each. Shoot them for groups and see if anything stands out. 44 to 45 is usually the sweet spot.

Heheh thanks man I'm not that bad at this. More concerned about what my col is gonna be n whether to trust the manual.or not (which is for bolt actions)

If you line the cannelure up to the case mouth you should be somewhere around 2.780" COAL. this is the proper length for this bullet. It's not meant to be jammed into the lands like some match loads may be.
