300 Remington short action ultra mag
Built a centergrip on another stainless model 7 receiver. Proud of this one as I was able to index barrel and get all trigger and safety items to work as intended. I did have a challenge on this gun. I took it to the range three different times. The first two showed promise and then flopped. Both times the brake shot loose and I had it on tight. Third time I used blue Loctite and it stayed put. I use a rifle scope on this one and because of the skinny barrel heating up I only shot three shot groups. The blast is impressive.

I think it is very similar to the 300WSM. I have found brass is harder to source. I have built a 300 Win Mag as well on a long action in a centergrip and I think it is best option for performance and brass availability.

Ps, glad to hear from you.

Years ago Brownells sold them. Lately I have got five from CDNN. LRI has a few hundred he is about to start to sell.

I really like the new rig you built, On the Model 7 actions, what trigger system do you use?
I have a 300 SAUM in a HS Precision 2000 pistol and it is a very accurate round and so far shots on whitetail have been impressive. I'm shooting the 150grn Nosler Accubond with H4831SC powder. And yes, the blast is impressive when you touch it off at first light or dusk when deer hunting.
What frame is the one you have? I would like to have a Model 7 action with a medium weight barrel in .243 and break that I could use a rifle scope on.

I use the xp-100 centergrip trigger assemblies including safety. I use the Model 7 bolt stop and I add a 1/4-28 threaded hole in the receiver for my mini chassis.

I am using the Muzzle Brake and More self timing brakes and I am using rifle scopes. The larger volume of powder works more and more effective.
