I love my 20" 30 nosler. Just check to make sure your can is capable of handling it, I would make sure it's rated for 300 rum@20" at a minimum.
Mine was built by LPR, Dallas is awesome. 20" bartlien carbon 8 twist, Bat Vampire action, XLR folding chassis, and 2.5-20 NX-8 sitting in NF 1.125" rings (needed the taller rings due to the short scope tube, adjusted for that with the adjustable cheek rest). Set up light with nothing on but a muzzle brake and a single shot tray installed, it is about 8.8 lbs. With a can, bipod and 5 round mag, it is 10.5 lbs. I could shave off about 5 oz if I didn't want the folding adapter, but short and compact and 1000 yard capable was the goal. Mine is a 30 nosler with a .215 freebore, and sends 208 Bergers at 2930 using H1000 in its accuracy node. I got 9 loads on a piece of ADG brass sending a 215 berger at an average of 2990ish fps with retumbo. I have also used the 187 apex afterburner, and I am currently testing the 194 Apex afterburner. The 187 was running 3000 fps with a moderate load, hit pressure around 3100. If you shoot at long range, I would recommend trying either of them out for a monolithic option. The 194 has a .357 G7, and requires an 8.6 twist or faster.
It has taken mule deer well over 1000 yards, and fits in my pack like this -
The PRC will have a little less performance than the 30 nosler, case capacity is less, right between a 300 wm and 30 nosler. But, should still be similar, and get great performance.
If you may be hunting at lower (sea level) elevation in Alaska, and plan on running lower bc (for bullet weight compared to c&c) bullets like a 214 hammer or the 208 barnes (which actually has pretty good bc for a barnes), you may struggle to get impact velocities above 1800 fps at 800 yards with velocities I would expect to see from final loads from a 20" 300 prc. That may or may not concern you, I know there are a few bullet manufacturers that state their bullets can go lower than 1800, however I personally prefer to keep impact velocities above 1800, and better yet 1900, so I'm not riding a line with a narrow margin. I prefer to just use a bullet with a better bc (which has other benefits) or use a bigger cartridge to get the desired performance at my intended max range. And it also depends how often you actually plan on shooting out to 800. Many people build 1000 yard rifles, but the rifles will never shoot anything alive over 500. Just the way it goes sometimes.
Bottom line, just consider all the parameters of exactly what you want to have in your build, research thoroughly, and make your cartridge, bullet, and rifle component choices based off those desired attributes and educated, accurate information. Regardless of what anyone else on the internet says. Good luck sir.
