IMR 8208 XBR in .223 load data

[DShortt]

I have a couple of pounds of 8208XBR I'd like to try in my bolt action 223. I want to use Hornady Match 68gr BTHP in a 1 in 8 twist 26" barrel. Not having any luck finding any load data, hoping someone here can help me out.

Thanks for looking.

IMR's data on 69gr bullets would be very close

Start at mid 22’s grains and depending on your brass and combination you might see the magic at 23.5-24.5
Be careful with that high end, bolt gun with long OAL.

Thanks for the link. I tried myself but I must have made a mistake, 8208 data wasn't available. Anyway, I appreciate it. Just what I was looking for.

8208 can have low nodes and higher nodes, when you hit the pressure limit it will let you know. I have used it for a long time in service rifle competition. Using different brass matters, :IE Lapua or Peterson such vs LC or RP or FED. I run a heavier brass with less h2o capacity so I found my prior loads needed to be lowered by .5 gr.
Wylde Chamber WOA Kreigers, Shillen and Wilson barrels on 20" service rifle competition rig. Hammers from 52-80.5 bullets from 100 to 600 yds.
Meters from a powder measure like a ball powder, very well consistent.

So bolt rifle I see folks really pushing the loads loads. As much as over 25 gr.
In my loads for the AR service rifle I have found low nodes shooting very well at 22.5, 22.8, 23.0 and 23.2.
23.3 in LC brass is the go to load for our game with 77 SMK/75Hornady match.
I found I did not need speed for accuracy at the low nodes. With the Berger 80.5/SMK80 I run 23-23.2 grains for 600 match loads.
Id start in the bolt rifle 23.2-23.6 and see if you get a flat velocity area, then once that is flat play with seating depth. Should be able to shoot small groups. As noted in many threads in forums there are folks really pushing the 8208 in bolt rifles alot higher.
Sadly 8208 has become a known good powder and hard to find anymore

I have had good luck with multiple bullets in the 23.0-23.4 range using 8208.

I looked for it on there a couple weeks ago. I couldn’t find it either, I use them as a reference a good bit

I was shooting the Sierra 69TMK the 69MK and the Barnes 69 match burner
out of a 26" 223 bolt action using 24.0 gr of 8208.

Velocity was around 2970-3010 depending on the bullet. I have a long throat
and the bullets were seated very long increasing the case capacity. For 69gr I would start at 22.0gr of 8208.

I had to back down to 23.4gr for 77s when I did a powder lot change with XBR. 23.5 would be a good launching point for 69s.
