Those are shooting much better in my rifle than 123gr A-Max and SST. Best loads I have for the A-Max are around 3/4 inch at 100 and SST the best load is just over an inch. These Bergers are 1/2 inch or less for all powder charges I have tried for 3 shot groups. Still doing load workup but the Bergers are looking real good for accuracy

Will my 1/9 twist shilen stabilize these!

What barrel length and powder are you using?

The rifle is a boltaction CZ 527 with a 22 inch 1:8.4 twist Obermeyer barre, see the thread in the Bolt action section of Grendelized CZ 527 for more on the rifle. There is another thread I started about these bullets that has a picture of groups at 100 yards. All loads are with CFE223. I started at 29.7 and started working up from there in .3 gr increments. 30 grains produced the smallest groups. This was with new Lapua brass, bullets seated for COAL of 2.285 inches. At 29.7 and 30 grains the primers were not flattened as much as Hornady factory ammo. but for now I will not be taking it above the 30.6 load that was still accurate but there were a couple that has swip marks from the bolt. .

As to getting the bullets, there was a run of them late last year that went mostly to ammo manufactures and I got a 500 count bucket from one I know. Already have another bucket reserved from him when he gets more in. In the mean time I told the guys doing the GrendelData site that I will send them some to do pressure testing on some loads for addition to that site.

I just got some of these in today, will be working up some loads soon. Contact euro optic if you're interested, they may have more

According to Berger, 1/9 twist could be on the edge of stability. What barrel length do you have? Checking the Berger site for their twist rate stability calculator http://www.bergerbullets.com/twist-rate-calculator/ You need to be at or above 2250 fps (assuming 80 degrees and 1000 ft altitude) to be comfortably stable to generate the spin rate necessary to stabilize them. According to he specs for the bullet from Berger, the G7 BC is 0.286 between 2000 and 2500 fps and the bullet length is 1.292".

With my 24" barrel, I am comfortably getting 2600 fps with the 123 gr Amax, so shouldn't have any problem keeping well above 2250 fps with a 130 gr bullet.

UPDATE

I found more info on the Euro Optic site (Thanks for the lead Grendel84) and the photo of the box actually states "for 1/9 twist or faster" and they have a PDF from Berger that has a bit more info than Berger's press release. http://www.eurooptic.com/PDF/Berger-AR-hybrid.pdf But...the bullets are PRICY!!! $45 a box!

Going to be shooting more of these this weekend, will be trying some in the 24 inch gas gun as well as stretching out the boltaction further than I have so far.
