Thread: Best LA cal for a short barrel

Lets forget about the 16" barrel and "efficiency" for a the rest of this discussion because 16 is too short and theres not a lot of options cal wise.

So lets go back to magnums.
How fast would you expect the 7RM to be in a 18"?
SAUM! what about a RCM. From what i have been reading they are designed for shorter barrels maybe not 18" but short.
What about the 375R!!!. you would loose a bit of velocity but would have plenty of energy!! It would fit in my mag 3.34 i think.
What other magnums? go nuts! a SS suppressor should control muzzle blast. it wont fire 100's of rounds so reloading costs dont matter. Or is this ludicrous and im showing my inexperience?
