BLC-2 powder?

Will this powder be good for 223 & 308 loads? I know it's been around a long time and am trying to find a powder for both calibers. The 223 bullets will be 62-75grs. Thanks

yup
It's oldscool powder for the 7.62x51.
It's ball powder, so it meters great and is appropriate for mil spec primers (CCI#34 and #41).
A little fast for heaver .223 bullets, IMO, but it will work.

Try Varget or AA2520 they will do the job that you need.

The BLC-2 is the powder that caused the fouling and jaming of the M-16 in Viet-Nam. It is also called WC846. The M-14 was not that affected by BLC-2/WC846 to any degree, so that powder continues to show up in standard NATO M-80 ball rounds. The Army took the same powder and required manufacturers to reduce the Calcium Carbonate (the ingredient that causes the fouling) and the new powder is called WC844....for loading 5.56 ammo since about 1969. So, can you use BLC-2 for 5.56 loads...yes, but the better choice in surplus powder would be WC844 if your shooting an AR-15 type rifle. Works fine in .308 as well.

Having said all that, stick powder, like 4895 or similar, is my preferred for accuracy loads in .223 and .308. Stick powder may not give the top speed in these loads, but usually the top accuracy. Just my opinion after 30+ years of loading and shooting these two rounds.

223 & 308 powder

win308 is correct, the best powder for the 223 and 308 is H4895 and IMR
4895. I've been loading these two for years and can tell you they produce
excellent results. E.S. and sd for either come out very good on the chrony.
.223 : 24.0 gr. w/60, 69, 77, and 80 gr. Sierras, Fed 205M or Rem. 7 1/2 primers.
.308 : 41.5 - 42.5 gr. w/ 155 Palmas, 168 gr. BTHP, W-W LR or CCI 34 primers.

[B]Start all loads reduced and look for pressure signs as all chambers and rifles vary !!

Ball powders [BLC-2] burn cooler and cause less throat erosion but they will not light tracer as well, I think they use a stick powder for that. I use AA2230 for loading 223/5.56, but I bought 32lbs of it years ago so I dont know if they are still making it.

look into IMR 8208 XBR if I remember right it works in both calibers. It's a short stick powder that meters well.

There are a number of powders that will work well in both 5.56 and 7.62x51 rounds. From my personal experience, AA2520 is superb with heavier bullets in both. TAC is also extremely good in 7.62x51, and is showing lots of promise in my 5.56.
