I fired about forty of these with little to no issues and then BOOM. Powder residue and the report of the rifle back in my face. Now the bolt of the rifle opened smoothly. I quickly found that the primer was blown and flattened and stuck to the bolt face. The gas pressure has totally screwed my extractor. Now I am asking those of you who have a 300 Whisper or 300/221 fireball...... What the hell?On the bright side of things, the new barrel/rifle is starting to break in and it is shooting rather well but I am a little gun shy after this incident. What gives? Is this SEE incident or what? Why after 40 or so rounds with no issues did this happen? Please share your ideas? Low and slow is my goal as I plan to add a suppressor to this rifle soon.
Thanks,
Jerryr
