So, I want to build a 20 inch 300 win mag to use primarily for hunting and occasional long range shooting fun out to 1000yds. Currently I hunt everything with a custom 16 inch 308 suppressed and has worked perfect out to 400yds. I want a caliber I can comfortably hunt out to 800yds with and of course there are a numerous amount of options, but I have my own personal preference I'm trying to satisfy.
My requirements are:
* maximum of a 20 inch barrel as I only shoot suppressed and a silencerco Omega adds an additional 6 inches
**Ammo has to be very readily available as I do not reload or intend to reload in the future**
* ammo has to be reasonably priced, $35 or less per box of 20 for match or quality hunting ammo
* caliber has to support a 1000rd barrel life (No 28 NOSLER! lol)
* Recoil sensitivity is a non issue….
Now, I KNOW there are much better caliber options for hunting, but I can't stress how important it is to be able to go to ANY sporting goods store and buy a box of ammo if I need to. This will be a dedicated hunting rifle and I have had numerous hunting trips where I have to buy a few boxes of ammo on the day of my hunt. 300 winmag has a ton of factory ammo offerings from light to heavy and I can't think of another caliber that offers as much of a variety. Barrel length is my Achilles heel, I KNOW Im giving up precious precious muzzle velocity by limiting myself to a 20 inch barrel but Im in Texas and do all of my hunting either in a blind, or walking through thick brush, and maneuvering a jousting lance of a rifle with a 24 inch barrel and a 6 inch suppressor is not gunna do it for me. I love shooting suppressed as well and a silencerco omega is gunna live on the muzzle. So i'm looking for some opinions on if there is a better caliber option that meets my personal requirements for the listed reasons, or am I moving in the right direction for my needs? Now I've seen good comparisons as in a 20 inch 300winmag is a 28 inch 308, which i'm more than excited about, but I've also heard potential negatives like a 20 inch 300winmag leaves too much unburnt powder in a suppressor. Let me know what you think, and if anyone has a 20in 300winmag tell me about it! Thanks
