SOS - Cannot find IMR 8208 XBR Anywhere for the "Onyx/Markm special"

[mic2377]

I've had good loads with the 8208 and H4895. The H4895 and 75 Hornady BTHP is a good combo. I also use it with the 24" Tikka bolt, different charge though. I don't have my book at the moment, but 22.8 +/- on the semi with 75's. Should be 23.2 with 77/8208

I love H4895 and the 75/77 grain bullets. Tried 8208 XBR and I actually came back to H4895. I run between 22.6-22.8 gr, loaded to 2.260 OAL.

If you haven't tried this combo before, you may find it shoots just as well as your 8208 XBR loads as well as being more forgiving and not prone to peaky over-pressure issues. The charge weight node is wide and it seems to shoot well in every AR I have tried it in.

It's OOS everywhere, albeit I am not too familiar on where to look (LGS, Brownells, Midway)

I have a PRS Match in May and need more. Any tips?

Also I am not sure where are located but I am in central OH and have 6 lbs of 8208 XBR available to help a fellow shooter out.

I've ordered from them a couple times and haven't had any issues...

That's XBR's main flaw. It'll turn on you like a snake.

I'd run LT-32, H322, or like you, H4895 and probably still be just as happy. You really can't make 77s shoot bad unless you really screw up.

22.7 gr is also my best load for H4895 and 77 Noslers . Not quite as good as my Varget and XBR loads but decent. I got it mainly for Garand loads but works in .223 at least on the heavier side.

Interesting...I'd like to try this load next time I have time to get to the range. Do you use Mil cases and some kind of SR-M primer?

In my 23.5gr H4895 under 77gr Noslers I use LC cases and CCI450s and it works great.

I haven't tried standard primers but I bet CCI400s wouldn't work too well.

Recob’s Target Shop in WI has 8 lb jugs OOS, but they have 1 lb containers in stock. Might help you in a pinch.

This is my favorite powder for 7mm-08 162 gr ELD loads. I mainly use TAC in .223/5.56 because it meters like water in my XL650. I’ll have to try 8208 and 75/77 loads sometime soon!

The milder the primer the better with extruded powders... at least for low SDs. If you're wanting to maximize velocities, Federal primers are the answer. Those Fed AR Match primers goosed our loads like 40-60 fps all else equal if I remember correctly.
