Default Very impressed with IMR 8208 XBR powder...anyone else using it?

I had a chance to out shooting yesterday at a shooting range in Dome Valley near Yuma AZ. I got to try out my 80gr Sierra Match Kings I loaded for 223/5.56.

I was very impressed with them at 400 yards. Very accurate. We were only shooting steel.

I loaded them with IMR 8208 XBR powder. 20.4 grains, and 2.550 OAL. Must single feed these. Here is the Hodgdon load data below.



With iron sights I was hitting 18" diameter plow disc that was made into a target.

I also tried Sierra's own load data of N140 powder, but had more accuracy with the 8208 powder.

Here is the Sierra load I used. 23.5 grains of N140.



I was shooting these from my AR-15. Anderson lower and upper. 16 inch barrel, 1-8 twist. Bullets stabilized with no problem. I tried last week shooting an 80gr bullet out of my NEF single shot rifle. At 25 feet it was already tumbling. It has a 1-12 twist I think.


Shooting area is being improved every time I go out there. It is now covered.



There are these plow disc targets set up every 100 yards out to 400 yards.

Yes.
8208 xbr using 140gr custom competition bullets out of a NM M-14 clone.

Shot my best prone group ever.

Shot a 100-9X on a SR-1

Found this load on a fluke just trying a new powder and projectiles.

Yes, 8208 is great for .223 and 308 Win. I use it often.

I also use 8208 XBR for both 5.56 and 308, but tend to favor it more in 308. I use H335 most often for 5.56, but have used 8208 XBR and it works well in 5.56 also.

I have gotten higher speeds out of other powders, but I like how consistent the rounds shot at 400 yards. I tried the same thing with N140 powder and they were not as consistent.

I do want to try Sierra's 90 grain SMK bullets, and also some Berger VLD'S.

I have been contemplating using this on my .243.

Using 8208 powder.


I tried ringing steel at 400 yards with 55gr FMJ's. They had little splash from the jacket blowing apart on the steel. Also very faint ring.

The 80gr 223's hit with authority, and looked like a small explosion when the jacket blew apart on the steel and sprayed the ground. They rung the steel like you would expect a 55gr FMJ bullet at 100 yards.

I have read the 90gr bullets are harder to get stabilized in a 223. They take a very fast twist rate and are on the border of spinning at to many RPM's and tend to blow apart or cause fliers due to gyroscopic deformation (over revving the bullet).

The only reason I tried the 8208 powder was the price. I already had N140 powder and load data for 80gr bullets. I was at 2nd Amendment Sports out in Palm Desert, and they had it on clearance for $21.78 per pound. Glad I did try it. I think this will be my new long distance powder for this 80gr bullet combo. I want to try it out to 600 yards next.

I did manage to push many of my Nosler ballistic tip 40gr bullets out to 400 yards with my single shot rifle with a scope. They were flying at 3800 FPS. Everyone asked what the heck it was. They made it down range faster then the 80gr bullet at 2500 FPS. I also tried 55gr Nosler ballistic tips. Not very impressed with them. The 40gr variety seems to be a sweet spot for this caliber for speed and accuracy. I did not use 8208 powder with the Nosler bullets.

I am fairly new to reloading and have used mostly h335 for my 223. I did pick up quite a few 77 gr noslers maybe 8208 will work for me.

I have some 77gr Sierra Match Kings I will also try with this powder. I'm hoping for similar or better results then the 80gr bullets.

I've found excellent results with 8208 and 80 vlds/90smk. You will need to run quite a bit over book max to find velocities equal to varget though. (If it matters to you) Obviously, do not exceed your comfort level or pressure signs.

I have had excellent results with 8208 with 175 smks. 42.2 in LC cases makes for accurate ammo.

Get your 80 gr load going better than 2700fps for 600yds,and then you will be on to something.

Using 24.0 grains on 55gr FMJ bullets for .223.
Very happy with it.

Have used 8208XBR with bullet weights from 52 SMK to Berger 82 with WOA A2 upper.

8208XBR is similar to H4895.

If you have an M1, 47 grains of 8208XBR with 168 SMK is very good. Also, works well with the 125 and 135 SMK.

I will try that with this, but will get a longer barrel. Maybe a 22" barrel would do good for 2700 fps.

I use IMR 8208 for my .500 caliber 20" barrel hunting rifle.

500 grain solid bullet 95 grains of 8208 averages 2,370 fps. Makes a potent elephant load.

450 grain hollow point 99 grains of 8208 averages 2,492 fps. Great round for big cats and cape buffalo.
