I am looking for data for .223 used in an ar-15. I got a bunch of 2520 on the cheap and I want to use 50gr. vmax bullets. They are moly coated if that makes a difference. Can someone give me min and max loads along with expected velocities?

Thanx in advance,
Mark

This is the only info I could find in .223 using 2520. I would think that 2230 would be better since it's close to H335 and H322 in performance, but just a little slower.

2520 just seems a little too slow of a powder for the .223, IMO.

mark; Accurates NRA high power service rifle loads for ar show - 24 " barrel

imi55 gr fmj(2.230 OAL)
aa2520- 24.8 @ 2837, 27.5@3224- 43,300 cup

the 55 gr is the lightest bullet they show in the hpservice rifle data

in there std 223 data they show

50 gr sp hp tnt- 24 " barrel
aa2520- 25.7-2944, 28.5-3346-42,200 cup

I think I gave this data before??, hope it helps

With 27.5 gr. of 2520 compressed ( as high as I've gone ) the 52 gr. berger is pushed at 3442fps.

One published compressed load of 28.5gr 2520 shows a velocity of3424 fps.
Difference in rifles perhaps. roger

thanx guys. I loaded a bunch of the 50 gr. Vmax w/ 25 grs. and 55 gr sierra game kings with the same 25 grs. we'll see how it works this weekend. From the sound of it, it looks like I should have tried to push them a little faster.

Thanx again,
Mark
