Oh, also I am happy to know you are alright and got away with as little trouble as you could have asked for!! 8.4 TG seems a lot and will surely be a rather stout load I guess. I use 3.3 in my 9mm.

That said: How about a squibb? Then your barrel gets sealed off and you fired another round behind it. I guess you looked through whats left of the barrel and there is no obstruction?

I use TG mostly and a lot. I have a light mounted shining in the case before seating and I look into each an every case when I seat the bullet. I am hoping to see any empty case or double charge.

I had a squibb once and caught it...lucky me. Thats when I installed the light.
