I just picked up a .300 Fireball barrel, and I built it into a complete upper this afternoon...



Does anyone have any favorite loads?



Anything I should be aware of when shooting this caliber?



It is a .30 cal barrel, but threaded .5x28tpi .... does anyone know where to get a .30cal flash hider in this pitch?



Should I bore out a standard A2 to fit it?



Thanks guys!

there are some A2 Fh out there that will pass a 9mm or 30 cal bullet with out being bored out. If yours wont, just ream it out.



What is the twist of your barrel, length, gas port location. All of tis will make a difference in the load that may work in yours.

JC,

Here is a link to some reloading data for the 300-221 fireball (a.k.a 300 whisper):

http://reloadersnest.com/frontpage.asp?CaliberID=135

You should also read through the 300 whisper forum on the quarterbore.net site:

http://www.quarterbore.net/forums/index.php?f=27

This should keep you out of trouble for awhile.

If you have any more questions let me know

Good Luck
