What is your go to 7mm Rem mag load?
I have 1st gen Sendero I had loaded up 168gn Berger VLDs Win Std primer 72gn of Retumbo and got it to shoot about .76 or so. I then sent it to Straight Shooters Supply in Oregon and had them Bed the action and install a Muscle Brake and recrown and tune the trigger to a crisp 2lbs. Got the rifle back and the same load I barely got it to shoot a 1.2 or so group. What gives???
I loaded some ELD-X's today some with retumbo and some with H1000 and Started at touching the lands and backed off ten thousandths from 3450 COL (just kissing the lands) to 3420 COL. With that said what is your method for seating depths on ELD-X bullets?

My go to load wouldn't do you much good. My 7rm chamber is a lot different that a factory rifle or other customs.  Using my data would not be safe and lock up the bolt on a factory rifle.  You are right there with your info on a factory load. I would try a mag primer though.  Sometimes when shops install brakes it can change accuracy.  This is typically due to the brake not being aligned or they went to fast during the machining process and opened up the bore at the muzzle.  Both are detrimental to accuracy.  Most all of the eld-x bullets will shoot in the .010-.020 of the lands range

I have shot both mag primers and STD and the STD primers in every load I tried shot better then mags.
I realize your load would be way different. Still curious what powder/primers work best for you.

I use retumbo and 215m primers in all my 7 mag stuff.

Curious what powder/primer combo you run in your .300 Win Mags?

[rbros]

H1000 and 215m or cci250 primers

Good to know.  Thanks.

What bullets are you using?  Weight? 

[rbros]

210 Berger hunting vld usually

Ok so 260 ai are you building them on short action or long action?  Seems that if you want to run the larger bullets then the longer action may be the route to take so you are able to extend them out or use a wyatt's mag?   Thanks for your answers to all the questions on here!!

The 260AI's are on short actions with Wyatt's mag boxes.

Have you done any load development with the 28 nosler?

A little.  Enough to know that the 195's are way more finicky to get to shoot then the 180's.  Its already a finicky cartridge, but the 195's make it even more so.

What's your process for cleaning a rifle, and how often do you clean it?  I have heard lots of mixed opinions.

Depends on the cartridge, but generally 300-500 rounds seems to be a good number for our competition guns to keep carbon buildup in the throat to a minimum.  Run a few wet patches of Butch's through it on a brass jag, then scrub with another couple wet patches on a jag, then dry patch it out.  Copper fouling is pretty much non-existent with our barrels after initial break-in so the Butch's clears out whatever is in there.  Make sure you use a good cleaning rod (we use Dewey), and a good bore guide like the ones from Mike Lucas.  Cleaning isn't rocket science, and is definitely one of those things you can overdo.  I've purposely not cleaned my 338 Edge for 500+ rounds and it showed no signs of being affected so I don't worry too much about that one anymore unless it get really wet or dirty while hunting.

I will have a defiance Deviant Action that I will be turning into a 6.5 creed.  It will be in here in March.  I am wondering if you give me an estimated cost for the following work.

22 inch barrel- Medium or heavy palma contour
Muzzle brake
Jewell trigger
Cerakote job

It will probably go into a chassis of some type, but I'm not sure which one, maybe an orias chassis.

I would also like to know your average lead times for builds. 

Thank you very much for taking the time to answer our questions.
