What are you guys loading in your 300 Whisper/Blackout guns for accuracy? I got mine on paper at 25 yards with some 220 grain Remington subsonic stuff. Premium bullets should do much better. This weekend I'll load some Sierra 240 HPBTMKs over some H110 to see if we can't do better. Stick them all in one hole up close and we'll go to Skyline and play at longer range..  |

I haven't gotten to load for accuracy with heavy subsonics yet. Have read that 2 MOA is about the best you can expect for 300 whisper subs. Though I find that unacceptable, I can't disprove it...

Subsonic hand and loads with 240 grain premium bullets showed one hole promise at 25 yards. Target had a bit of side to side movement.  |

Nothing! lol
I've been shooting the 300/221 since the late 90's, 4 different contender pistol barrels, one contender carbine, 3 AR's and one bolt action rifle and I don't think I ever got better than 3/4" 100 yard groups. 7 of those 8 from different makers/builders. That doesn't have to mean anything really, lots of variables and possible reasons, but I never got one to shoot well enough to impress me. I love the round and I still have one, but for me it's never been a prize winner accuracy wise.

I do not have experience with the 300 Whisper, but I remember the various articles when it first came out. I've been intrigued with the cartridge ever since, just haven't pursued it. I'm surprised to hear that accuracy may not be the greatest. It looks like it has all the potential to perform very well.
