Hunt ready (scoped, with bipod, and 3 rounds in mag) as seen in the pix is 12 lbs. My best guess is 9-9.5 lbs without scope and bipod. The JP Beenie Cooley MB is simply amazing and makes a huge difference.
Thanks!

I'm digging this thread up from the grave... How did you end up doing with the AI loads? I'm thinking of building a 270AI and I've been collecting nosler 150gr long range accu bonds to shoot out of it.
I settled for 58 H4831SC WW brass CC BR2 pushing the 175 Matrix at 2993 FPS. I still have the 165 Matrix and 150 LRAB to play with but haven't had a chance to explore them yet ... hopefully this year along with the Berger 170.

I just hope my barrel will stabilize the 170gr bullets. I wish I had known about the Berger 170 before ordering the barrel. I got a 1-10" 5R twist rifling assuming none of the bullet makers were going to make a bigger .277 bullet. Looking back I wish I had got at least a 1-9" and added an extra 2" to make a 28" instead of 26" barrel.
I monitored the 165 and 175 fairly closed in 2012. The Berger 170 was already a concept at the time; it took longer to become a reality but it is better late than never.
Also, consulted with my gunsmith, Dan Lilja, and Marshal Ambrose of Matrix before jumping into 1:8" with high hopes of other bullet manufacturers to develop .277 BC bullets.
If it is not too late for you, I'd go with the 1:8". Just ran some quick numbers for you, if you can push the 170 at 3000 FPS and alt of 3204 FT (Rapid City Regional Airport).
Good luck!

Thanks Ed
Unfortunately I have had the barrel blank sitting on my desk for nearly a year, so there is little I can do other than try and sell the barrel and order another one. I placed the order about 18 months ago and received the barrel about 6months later. I never really considered Matrix bullets so the only choices I knew of were the LRAB and the Berger VLD both of which were 150gr. I might see if there is any interest in the classified section for the barrel...

After the hunt yesterday, I decided to have a little fun with my oldest son visiting from Florida.
Picked a target rock at 936 yards and send some 175 Matrix VLD at 2993 FPS out of my .270 AI. I told him he's got 3 rounds to send and hit the target. Made 20 MOA (rounded up from 19.6 MOA) of elevation and 4 MOA (just a WAG; 20-25 MPH right to left) of windage correction.
The impact was ~6" high and ~6" left from point of aim on his first shot. Not too bad for first time behind the trigger ... he called it good and he's one happy camper. I too am happy for him and the rifle. gun)gun)gun)
Cheers!
