Not enough neck tension

Just got done annealing my 300 win mag brass for the first time for this rifle after the third firing. Using the templac on the inside of the neck it would burn up at about 10 seconds. About a second and a half after I would first notice the full red glow. I loaded some up and shot them. They shoot great as always. Great like 1410 yards first round impact and 6 more shots directly after on a 15" steel plate. So the accuracy is fine. I have my 100 pieces of brass sorted so half take .334 bushing and the other half take a .335" bushing. The shooting I was talking about we're the lot with the .334" bushing. Today I loaded the .335" lot and noticed how little resistance there was seating bullets. After a couple I tested the tension by pulling and twisting on a bullet and it was very loose. I pulled those bullets, resized the necks with the .334" bushing seated bullets. It was a little more resistance. I twisted the bullet in the casing and it moved. It was tighter than the .335 bushing but still moved. I tested a bullet from the other lot that was shooting alright and sure enough it would move too.

A couple things I can think of, let me know which you think or if its something else. Did I over anneal it and there is no elasticity left? Does brass grow thinner at the neck with each firing and I need to drop down in bushing size? Does air temperature have to do with it? By steel wooling the outside of the neck before loading actually take off a little material?

If I would have to guess I would say I over annealed it. If so is it unsafe to shoot? I was heating just the necks and quenching in water after. If so, how does it still shoot so well?

Thanks for the help.

Re: Not enough neck tension

Just curious...what is templac? Is that some kind of temp indicator ? I never bring my brass to red hot...just till the temp line ( a bluish line from the heat )moves down about halfway down the case, and it does' nt take long, and then I let the case cool to ambient by itself. Heating to red hot and quenching is a hardening process, in my expieriance. Dont take offense, I mean none, but if I shot like you are, I 'm not sure I would change ANYTHING I was doing! You know, if it aint broke, dont fix it kinda thing. Do you single fire, or fill your magazine ? Shucks, like I said, if it aint broke....
P.S. Steel wool is harder than brass, so, yes, it cuts the brass. I am not sure if it would remove enough to get concerned about, but I sure like the look and feel of my brass after I buff it up with the wool. Maybe I will get to learn something here...anybody got any thoughts on this?

Re: Not enough neck tension

have you had to trim the brass? sounds like you just need a smaller bushing because the neck has thinned

Re: Not enough neck tension

Does that happen? Do necks just thin after multiple firings? I trimmed my brass uniform when they were virgin but haven't since. They were pretty short for my chamber so trying to grow them out. Is it possible that 10 seconds in a 1" propain flame is too much for a 300 win mag spinning in a socket? That was repeatedly how long it took for the templac 750 (or 700 can't remember right now) to burn off from inside the neck and about a second and a half after I first started o notice the neck barely turning cherry. Thanks

Re: Not enough neck tension

Single fire. I have a mag but when target shooting just single shot so I don't scratch the brass. If I were to feed these through the mag I would imagine it would push these bullets deeper into the case. Hope I can figure this out. Thanks guys.

Re: Not enough neck tension

you anneal before any resizing is done correct?? or do u resize.. then anneal?? I haven't had any problems when I have annealed brass for the 280 lately.. I just deprime... clean in the sonic cleaner.. then anneal.. then I resize the brass and load some bullets!!!

I anneal for about 5 1/2 seconds in a propane flame while spinning the case in a battery powered drill. You may have overdone it. I bought the 650F Tempilaq. And the Templilaq is supposed to melt at the indicated temperature - not burn off or away. You could try bushing down another 0.001 and see if the case mouth holds the bullets. If not, you over-annealed, IMO. Doesn't make the case dangerous to use as far as I know, but the bullets may not stay seated and your groups or POI could change a little.
