Grendel/Lapua 123gr Scenar/IMR8208XBR anyone?

[1340]

I've been working on a Grendel load using Lapua 123gr Scenars and IMR 8208 XBR.
I have Lapua brass and Federal 205M primers. This is for a bolt gun. The data I have for 123 gr. bullets lists
25.5gr to 28.5gr of powder. With the length of the Scenars I get to about 27.4gr of powder and I think
the powder starts to compress. The powder is at the shoulder area and shaking the cartridges doesn't really
make any sound.
Has anyone tried this recipe?
Any advice?
TIA

I’ll
Have to look what my load was but I was running 130 Berger ar hybrids with 8208.
Worked great in my howa mini

I use Lapua brass, CCI BR primers, 123 gr. Scenars, IMR 8208 xor. Very accurate load in my Ruger Ranch. Also use Starline brass. CCI 450 mag primers, Imr 8208, 123 Scenars, another accurate load.

C1A1 was introduced to the Grendel by me, and his load and mine are pretty close. As I shoot out my stock of XBR I'm switching to Dominion D8208, I'm just on the edge of pressure signs with 27.4 . I'm now using a Ruger Predator with 20" barrel.

definitely back off switching to D8208BR, the lot# I Have is much faster burning than any IMR 8208xbr I've shot

Yes right on the label it says back off 20% and retest. IE ladder load test

Far exceeds the accuracy I was looking to get out of the rifle, so I haven’t bothered with pushing it harder. 8208 has worked great, plan on using it with my upcoming 223. Wylde build.
