As per my problems here:
http://www.quarterbore.net/forums/showthread.php?t=4556
There is concern that my supersonic loads are too hot and causing these issues.
18.5 grains of H110 with a Nosler Ballistic Tip 125 grain bullet. OAL is 2.045
Reason I went with this load is I chose it from this link:
http://quarterbore.com/300whisper/supersonic.html
On that link they are recommending 22 grains of H110, so I loaded down more than 10% but apparently that still doesn't work.
16" barrel, 1:10 I believe, pistol length gas tube running TP555 adjustable gas block in the H position, of course.
What suggestions, if this is too hot a load, would you suggest?
