My loaded case measures .366 in a .338 LM . I have bushings from .362 to .365 and my bullet will push into my case body with moderate pressure , is this normal or should i go smaller than a .362 bushing even though a loaded round is .366. Thanks for the help
 
This is the first time since annealed but i have new brass never fired that does the same thing and it is lapua brass.

I have loaded 1000's of 338 Lapua rounds using Lapua brass and a Redding bushing die with a .365 bushing. The only time I ever needed a .364 was with some 4 times fired brass that was springing back. I annealed it and went back to the .365.

Now it is very possible your lot of brass could vary a little in neck thickness and you could need the .364" In fact your measurement of .366 would lead me to believe you would use a 364 or maybe a .363 but I cant see for the life of why you are getting so much spring back.

Maybe measure a fired round and record neck dia.

Then size it with a 363 and measure again before you seat a bullet and report back here.

How did you anneal it?
