300wm neck tension

[Drop Port]

Only several hundred rounds. Most were loads others used. They shot as well as theirs; about half MOA or better.

My 6.5x47L shot half MOA or better from the get go and as soon as I gave it stiff neck tension it sucked em into the one's and two's with single digit ES /SD. When my barrel goes back to 1/2 MOA or better it's getting tossed.

If I never tried what others say wont work my Roberts would never of shot, who'd a thunk it a Mag primer

You do understand that you are conversing with guys who have tested 10s of thousands of rounds.

You "several hundred rounds" is not much for you to learn so much about neck tension.

If anyone has kept all record groups from a given barrel under 5 inches at a thousand, then I'll consider it.

Have you ever shot to 1000 or beyond?

Another thing to consider ......size matters. It's not the length, it's the thickness.

Oh boy...where have we heard THAT before?

Ok...minds out of the gutter...I'm talking about neck thickness. I used to run .330 necks (.328 loaded) and I needed .006 to .008 neck tension to give me the same "hold" as .002 with thick brass in stock chambers. Think about it...if you had two pieces of brass with the same exact ID....say .002 smaller than the bullet..... but one neck was paper thin and the other MONSTER THICK, which one would give you more "hold"?

I now chamber all of my 30 cal bbls (300 wsm and WBY) at .334 ( .332 loaded) and need around .004 ish hold....depending on the bbl.

What I have found...at least what I have experianced....is that once you find a neck tension that works in a particular chamber for LR, that is what always works...no matter what bullet you shoot. I used to do a lot of "testing" trying to find that magic "sweet spot" and have seen it pretty much with every tube.

Now, what was said above about jam vs jump vs tension...I can't say, but that is because I ALWAYS, ALWAYS run them into the lands and have never tested...but, it makes some sense.

PS.. I HAVE shot and tested at least a few shots at 1K , and no, I have not saved EVERY target I have ever shot, but I do have a few of the ones that really "count" hanging next to some of the wood that really "counts"!!

Bullet release force in my and others tests for accuracy.

Please explain how a rifle "wants" anything. None have a nervous system nor a brain to think and have emotions.

I think that the reference here has more to do with the performance of the load in a rifle rather than the rifle itself.
