215 Hybrids in Factory rifle

With factory ammo you may be correct, but in my opinion, with hand loads, the 300 WM really shines with projectiles in the 200-220 grain range. I have loaded for the 300 PRC, and I would agree projectiles in the 225-245 grain range might be ideal, but it would depend on how one defines "ideal."
Yes, it would be with hand loads. I suppose the best way to test this is to take each load to pressure signs for a max velocity. Then you could find the "best" (most accurate and velocity) load in each and compare as well. Now to convince the wife I need to spend 4k for scientific purposes🤣
 
Good info! What I would really like to do is a prc/ win mag side by side velocity comparison. Most comparisons run the prc with a 220-245 bullet and a wm with a 180. I'd like to see same gun, barrel length, powder type, brass, and bullet (215). Would be interesting to see the difference
I can load 212 and 215 grain bullets in my 300WM to higher velocities than factory 300 PRC ammo in the same bullet weight. I load to 3.690", so full use of the 300WM case capacity.

Not sure if I can do the same with 220-245 grain bullets.

I'm sure you can beat 300WM velocities in all bullet weights if you handload the 300 PRC.

Either way, I actually download the 215 Berger Hybrids to 2,800 fps (I can get +2,900 FPS). I get great accuracy at 2,800 fps and have more than enough velocity/energy with that bullet to shoot elk and deer at hunting ranges I'm comfortable/confident at.
