Reloading data for military bullets...145gr .308 fmj?

I tried searching the forums but could not find what I am looking for. Sorry if this is a repeat question. I recently received 500 bullets that are 145gr military fmj with very slight or no pull marks. I want to find reloading data for it, specifically for BLC(2) powder. Any suggestions?

You might try letting us in on what cartridge you are trying to reload (30-06, 7.62X51 NATO, 308 Winchester, 300 Win Mag, etc). There is a lot of data available for FMJ for 308 and 30-06, less for others.

I assume you meant a .308 cartridge from your post title? If so, then about 46.2 grains of BL-C(2) will mimic a NATO load in a military case, and 48 grains will be needed in a Winchester case, which has about 8% more powder capacity. As always, work up from a 10% reduction and watch for pressure signs.

Thanks for the info. Yes, .308 is the caliber. It will be used in an M1A.

I came up with approximately 46.5 BLC(2) but I don't like guessing. I suppose I wasn't too far off based on your 46.2.

I will start with about 42.0 and work up from there. Sound about right?

thanks again!

From the Hogdon manual #25, for 7.62 NATO ammo using GI brass, max load of BL-C2 is 47.0 grs running at 2719'ps with a 150 gr bullet. The lighter bullets should be well on the safe side using this as max data. Using Winchester brass, the data goes 49.0 gr BL-C2 with a 150 bullet running at 2878'ps. In a 308 Winchester, the load for the 150 bullet is 49.5 grs BL-C2 running at 2835'ps using commercial brass. I would probably consider that 47.0 is pretty much max regardless of the brass. While I like my Armscor all military parts M1a, I'm not game for getting beat up by it. My experience says that the M1a's usually shoot just below max loads anyway. You may also find that you are starting a little low. I have a neat load with 2520 that will work the action and cycle just great but it isn't quite enough to reset the sear- it goes full auto until the clip empties. You could easily be in the same ball park. If you start this low, be aware that you too could have a legal semi auto machine gun. Use caution.

Trapper, thanks for the info.

I'll see what happens when I work up the loads, but, just dinking around and putting charges into the brass it sure seems like 46.5 of BLC2 would make for a compressed load, hardly any room for the bullet if I want to keep the COL reasonable. The brass is once-fired military.
