IMR 8208 XBR

IMR 8208 XBR powder.....any of you guys load it?

Your thoughts on it?

I have heard good things about it, on another board....now time to ask guys.....

Rifle RRA NM in 5.56 62 grain Hornaday and 69 grain matchking

200 yard range, but I want to be ready to shoot XTC, now that I have the rifle to do it

Otherwise I'm thinking of trying RE15 ....... currently loadingbwith CHE223

It has done well for me.
20" RRA NM. 69g SMK. 23.3g XBR. 2630fps avg.

That is my go to powder for long range AR shooting. I mainly load 77g SMKs on top of 22.9g of 8208 XBR. It's a very accurate combination for me.

It is what I load for my .308. It has done very well for me in that caliber. I'm experimenting with it in .243 and .223. Preliminary results are promising. I initially went with it because of a difficulty finding RE-15 during the panic years.

 

[natdscott]

Do you already have it?

If not, and you already HAVE RE15, just load RE15.

Either way, the 69 MatchKing with about 24.5 RE-15 is one mean SOB.

I love the 8208. It is very temperature tolerant. 55 grain Amax over 25 grains of 8208, is an excellent 200 yd load. I never played around with heavier bullets much.

XBR is a go-to powder for 223/223AI cases with heavy bullets, or 308s with 168gr and lighter bullets. Generally known as *the* 308/155gr powder.

23.5gr XBR under a 77gr bullet makes a great Mk262 clone.

 

[natdscott]

avboiler, how fast can you get XBR to go in that clone round? Will it better RE15 and stay under pressure?

I cloned it once for a guy, but did it with RE15. It was hot. Still safe at 120 degrees, but certainly wiping brass and flattening primers. Brand new LC09 though.

Never used RL15.

2740fps from a 18” 1:8 rifle gas BHW barrel with 23.5gr XBR under a 77gr Nosler.

BHA Mk262 white box was 2760 in the rifle, which 23.8gr XBR gave me but 23.5gr was more accurate. I ran up to 24.0gr without issue but no need to run hot overly loads in a gas gun IMO.

Only if you want to shoot Palma....

It’s my go to when loading.223

 

[mdunn]

Just picked up a couple pounds of 8208 xbr and some 155 Nosler custom competition bullets.Any suggestions for a good accurate load? Shooting a DPMS lar 308 with a 18" heavy flutted barrel,full float forearm and a Rock River national match trigger.

It and CFE223 are what I keep on hand to load heavy .223 and 6.5G.
