I just got my build back from Benchmark Barrels, a 7mm Dakota. Figured I'd post some pics of their work and update this thread with range results and some long range data/footage. Here are the specs:

-Defiance Deviant Hunter action, Sniper Grey cerakote, Devcon Ti bedded
-Shillen trigger @ 2lbs
-HS Precision DBM
-McMillan A3 GAP stock
-Benchmark Barrels #6 Kreiger contour 1:9, 6 flutes @ 26" plus brake
-Mini Muscle Brake
-American Rifle 34mm rings
-Steiner T5Xi 5-25x56 MRAD scope

Looks like a shooter for sure! What do you expect your reach is? On a target? On game?

On steel it'll reach as far as I can shoot, sub one mile. On game, I plan to keep it under 1k but that depends on the species

4 legged canine predators have a maximum range allowance

I'll be shooting 190gr Matrix VLDs between 3000-3100 fps

Sweet Setup! Looking forward to seeing the results on both steel and game.

Nice rifle how long is your barrel? Benchmark is working on a barrel for me right now. Can't wait to build mine.

Very nice rig, LoJack. Hope to see it in action in a couple months.

sweet setup! I did the re-barrel deal they had a while back, and should have mine any time as well. can't wait to get my hands on it

Wingin it · « **Reply #8 on:** June 20, 2015, 08:54:14 AM »

I am waiting on one from Benchmark as well. I can't wait to get it back and send some rounds down the tube! Should have it back in the next couple weeks.

Biggerhammer · « **Reply #9 on:** June 21, 2015, 06:19:32 PM »

The 190gr Matrix is a IMPRESSIVE bullet. I run it in a 7mm WSM with a 30" Hart 9 twist barrel.

safehunter · « **Reply #10 on:** June 21, 2015, 06:46:41 PM »

I'm thinking you need a bigger back yard to use that thing to it's potential!! Nice looking rig!

Going to head to the range on Saturday. Group it at 100, 200, and 600 to see how the load works. The 190's will be a hammer

You know what they say Darren. I will say MSRP on the rifle is about $3600, scope MSRP is $1850

Can't go wrong with a Benchmark .338 barrel. They flat shoot!

The rifle was 14lbs. It was fun to shoot, just not to pack. I'm thinking I'll have them build me a .338 Lapua Improved in the future

I know very little about the hardcore specs of rifles. But some of the rifles on here make me have a wet spot in the morning. Very, very impressive on what kind of toys a guy can have, build or buy.

I got my first trip to the range in with the 7 Dakota yesterday. The pics are in order of the first groups through the virgin barrel. They closed up a bit, I need to knock the rust off my trigger finger too. That group is at 77.6gr of Retumbo behind the 190's and .020" off the lands. Thinking I'll bump it it down to 77.3 gr and it should help tighten it up.

Pics are sideways for some reason. That square is top of target

Biggerhammer · « **Reply #33 on:** June 28, 2015, 08:03:08 AM »

Off to a good start. Did you get your Matrix bullets from Benchmark or did you order direct out of Canada? I'm still a little on the fence for my next rifle from Bencbmark. I talked to Chris and more Deviant actions are coming in. I just am at a toss up between the 7mm Dakota or a 10 twist .300 Win Mag throated for the Berger 230 OTM's. As of now I may mess with the Dakota later.

xXLojackXx · « **Reply #34 on:** June 28, 2015, 11:55:47 AM »

I ordered mine direct. Great customer service. I think i ordered them at like 9pm and they shipped out the next morning with tracking info. Going through customs takes a couple days more, but I buy enough to last me all year.

Haven't bothered chrono'ing the load yet until I'm satisfied with the grouping. My next step is to increase the jump between .020" and .040". Should help those long VLDs tighten up. I'm after one ragged hole on paper. Once achieved I'll run it through a chrono.

xXLojackXx · « **Reply #39 on:** July 13, 2015, 08:43:13 AM »

The final load development I settled on is 77.6gr Retumbo behind the 190gr Matrix VLD sitting .030" off the lands with a BR2 primer. I ran it through a chrono which gave me an average of 3063 fps with an SD of 8. I finally got a chance to get up to 5000' to see how it does downrange. I shot at 3 distances, appox. 680, 1180, and 1405 which needed 3.4 mils @ 680, 7.5 mils @ 1180, and 10.1 mils @ 1405. 6 mph steady crosswind with 10 mph gusts. The video is a bit shaky but you can make out vapor trails and impacts. The camera died right as I was setting it up for 1405 yards. Next time

Are you a muzzlestuffer also? Seems that the only people that benefit from the multi-season permits are the local sporting goods stores.
