Deciding My Next Rifle’s Chambering

The age old story. Hurry up and wait.

This is how I like to set my 7 rem mags up with a 180 hybrid T. This round sets .025" off and is 3.565" COAL View attachment 445080

Pretty much how I have my dummy round setup!

For what bullets I wanted to run the most 175 eh and 180 HT its perfect

I was hoping you'd chime in and share your .264 build; it would be pretty close to what the OP is trying to do in .284.

I don't think he's wanting to deal with non SAAMI cases based on posts I've seen.

I would be glad to share if he requested.

Didn't you have a .264 WM improved (non-SAAMI)?

@Jud96, looking at your build what ever cartridge you go with it is going to be a sweet rig! With a good chamber you should have plenty of case neck bearing surface. Will be fun to see what you can get out of this setup.

Lance is building a 300 WM and has a thread on LRO. Jud's and Lance's threads are killing me lol.

Found it!

Mine shoots tiny one hole groups in the .1-.2 range and I've only shot one animal so far and it ended up being a spine shot so I can't say how it would have performed otherwise. This is at 3350fps from my 264 Win Mag Improved.

Yes. I thought Jud had said he didn't want to fool with a non SAAMI cartridge on this build.

28 Nosler? ADG Brass is readily available now from various sources, don't have to run N570 to have the upper hand on most the other 7mm options and if not using as a "play" piece - barrel life should be decent. Not to mention it should be decent SAMMI spec'd.

I guess I miss that part.

I favor the 7mm Rem Mag for these reasons. Brass is probably the easier option to get. It has slightly lower operating pressures for similar velocities. Reasonable powder charges that are around 70 grains or less. And a large load data pool to select from. It's kind of like the 6.5 CM vs 260 Rem debate. The cartridge design might be "updated", but for a smith and/ or reloader the "updates" are a non issue. We'll work around them.

7RM and ADG brass, has everything going for it. Here's the last one I worked up a load for 26" Brux, mild load of RL26.
