I hit the range today to sight in a few Rifles for friends and a neighbor, Man! I was madder than a wet hen. I had a great load for the 7MAG and when I would fire, it would go snap BANG! it was a half second after the primer was made contact, there was a real good hit on the primers, some did not even fire and I was using CCIs BENCHREST. I have never had a problem. this is the first time I have ever had this situation. I just bought them, I had another batch in my .35 and they worked better than expected...Well I got some bullets to pull. We got all kinds FORSTER, RCBS, HORNADAY and a Davidson. have you any input right now I am a bit upset to say the least. I need to buy a puller. The loads I did with the 160grs were dead nuts on 35yards and dead at 100 also. as usual my .35 just made one hole with 3 shots..My .3006 it made a string with three shots in the red. so I am good to go. Exept the 7Mag. DAMN!
