300 prc
originally, It was the 30/375 S. I. when I designed it off of the 375 Ruger about 10 years ago.

So if it's a shortened 375 Ruger case with a longer neck, then it's basically a necked up 7mm LRM? Or is the overall case length shorter?

I'm assuming SM stands for 'short mag'.

I have a 338-375 Ruger and my load runs 250gr Bergers at 2980 fps from a 26" barrel. Will easily hit 3000+ fps, but my accuracy is at 2980. The Ruger case is very efficient and produces some impressive speeds in all its variations.

SM=Sherman Magnum though I liked "prissy" better "300 PRC SI = Sherman Improved "

7 LRM is shorter at the shoulder than the 300 PRC

"SubMOA" as shown on the screenshot and post #43. I'm guessing that's the Apple version. Looks like "Range Buddy" for us Android people. There is a paid pro version too. Not sure what that entails.

.1 moa at 492. Gonna call it good until I can get to ranch and shoot to 1000.
Final load 245 eol with 82 grains of N570 at 2950. Seated at 2.856 bto , 215m

It takes the exact same case as 300 prc. Once you fire the case it will get the shoulder to the angle you are needing. Shoots factory 300 prc 225eldm very nicely in most guns I have seen.

By the way this adg brass is great. Have not had to trim once.

I know 3000 is doable with the PRC.

With a standard 300 prc?? I call bs unless its a 30 inch barrel

Some people are willing to or are unintentionally running 70K PSI, eg the 6.5 CM running 140s. It takes pressure to get you there.

Not with a 26 inch barrel and 245's with a standard 300 prc
