Another victim of KABOOM
I too had similar issues with H110 in my Remington 700 300/221. Not to the extremes seen here but I sure did get an eye opener and after 25 years of handloading....I am lost. I followed Sierra's loading data of 10.7grs of H110 behind a 200gr SMK. This is a low end starting load. Had 50 rounds loaded. Had fired forty of them over the course of a week and then BOOM. Why have the others worked out so good and then the mishap? I weigh each load to the 1/10 of one grain. Did I screw up and over/under charge a case? No, I pulled the bullets on the remaing rounds and weighed each charge only to find that each charge was exactly 10.7grs of H110. Was temp an issue? Don't think that was an issues as daily temps were 65 to 70 degrees. What gives? If this is symptoms of SEE then I will not use this powder again for I intend on a lower charge in an attempt to get in the 1000 -1050fops range for subsonic use. I also have AA # 9, AA1680, AA 2015 and VV N110 to play with also. The H110 has me gun shy to say the least.
