98Z5V Posted March 17, 2014 Report Share Posted March 17, 2014 Well that answered the question on the other thread... It fits ! It fits if the projectile gets set back into the case. I was wondering about that with a supersonic load - even at 16.5 grains, that fills that little case up pretty good, and I don't know if you could set the bullet back enough to get the thing to go off. Didn't even consider the amount of "unused case" in a subsonic load. Shibi, how much powder is going into the subs? Quote Link to comment Share on other sites More sharing options...
shibiwan Posted March 17, 2014 Report Share Posted March 17, 2014 (edited) Perhaps the bullet gets rammed in when the bolt slams shut. Using 208gr projo's with about 10.6-11gr of AA1680. It's a really fine powder so it does settle down more compactly. Edited March 17, 2014 by shibiwan Quote Link to comment Share on other sites More sharing options...
planeflyer21 Posted March 17, 2014 Report Share Posted March 17, 2014 Obviously it is possible to make a 200gr .224 projectile. They may have just made the .300 Blackout obsolete. Quote Link to comment Share on other sites More sharing options...
survivalshop Posted March 17, 2014 Report Share Posted March 17, 2014 (edited) If you set the bullet completely into the case or close to it & may depend on bullet /powder to have enough room to set it back far enough . I just tried to chamber a 125gr. 300 BLK into a 5.56 chamber & there is no way it will chamber . The H110 I'm using would not let it set back into the case any way . The BCG was about a 1/2 " out from seating , an empty case will lock the BCG & you can drop the firing pin , but case mouth was deformed a little . Now the Sub's may be different , another reason I like the lighter ,faster , stronger bullets :auto: Edited March 17, 2014 by survivalshop Quote Link to comment Share on other sites More sharing options...
98Z5V Posted March 19, 2014 Report Share Posted March 19, 2014 ^^^ That's exactly what I thought would happen - with a supersonic round, you've got enough powder in that small case that you can't set the bullet back far enough to close the bolt. Which is necessary to render the firing pin in a position to contact the primer. Quote Link to comment Share on other sites More sharing options...
seasprite Posted March 19, 2014 Report Share Posted March 19, 2014 Wow, I just don't know what to say after seeing that other than pay attention to what your sticking in the rifle. Quote Link to comment Share on other sites More sharing options...
