[QUOTE="Jcalder, post: 5432939, member: 12150"] Had some misfires today. First I've had in a rifle that's got my stumped, but I think I know the issue. Just wanting to confirm. Recently had some loaded that I want gonna use in a different rifle. Sold that rifle and decided I wasn't gonna use that powder in the new rifle so I broke everything down. I DID NOT resize my brass and I think that's where I went wrong, but I'll continue on. When I reloaded the brass I noticed I could potentially push the bullet in by hand. It was kinda hard to do, and in my mind it was fine. When to chrony the loads today doing my development routine. First one chambered hard. Didn't think much of it and touched it off. Misfire. Pull the shell out and looked it over. Put it back in the rifle and it went. Next one was tight but sent fine. Third one was tight and I started scratching my head. All my notes show the headspace in new gun is the same as the old gun based on fired cases. I had set my bullets .020 off the lands. Why are they tight?!? Touched it off and another misfire. Pulled it out and the bullet stayed in the barrel. That ended my mission right there. I took everything in and pulled my loads, resized the brass and started over. Couple things that should be known….. The brass is 270 FC brass converted to 25-06. Annealed afterward. Possibly over annealed and soft, but I don't know. Basically I hit it for about 5 seconds with a torch being spun in a socket. I kinda think that when I pulled the bullets initially I didn't have the neck tension I should have had. But could the brass have pushed my bullets out if the base of the bullet was above the shoulder/neck intersection? Powder is imr 4955. I know it's discontinued, but I have nearly 5 pounds. That's enough to spend time on making a load. So my question boils down to is the lack of neck tension why I had the misfires, or is it something else. [/QUOTE]
