At this time I don't have time to reload. So I bought some Corbon 300 Whisper ammo to shoot through my 300 Fireball. I had to put a carbine length spring in my full length tube to make them to eject out of my 16" 300 Fireball (model 1). Then I got a hold of some cheaper $20 a box 300blk ammo. (Compared to $40 a box Corbon 300 Whisper,) and they chambered and ejected perfect and seemed just as accurate as the 300 Whisper to me. Go gauge said go. So 40 rounds of BLK no fails to feed, shoot or eject. I think the 300 Whispers were quieter.(no suppressor) Maybe do to the less depth of the 220gr. bullet? Does anyone think think the less depth would mean slightly better accuracy too? You can tell that the shorter BLK feeds quicker/smoother. Which factory220 loads do your reloads resemble more? Corbon or Rem?
