    A puzzler for y’all...

    Why is that? Brass does not quench harden. Once it reaches your required annealing temps it shouldn’t matter how quickly it cools. That and I’ve got a limited amount of room, pretty handy to just drop hot stuff in a bucket of water.

    A puzzler for y’all...

    Sounds like you thought the donut would be formed or forming at the shoulder/neck junction correct? I suppose it could be happening but the bearing surface of the bullet isn’t close enough to that area to be influenced by a donut if it was there. I inspected the neck id and od pretty closely and...

    Now that was a good question I hadn’t thought about. The bearing surface of the bullet never reaches the shoulder jct. By my caliper it is .110 from it. No way a donut in the shoulder area is causing this.

    No way I’d get that much without milling the shell holder and @918v is right. Would sure work the heck out of the brass.

    I punched the fresh primers and annealed a few rnds, just gotta wait for them to dry.

    Can you explain what the donut is and what’s causing it please?

    Ah fat fingered it, once fired sized .348

    No the .337” is new unfired brass, new loaded is .348”.

    Don’t have the gauge and no spent .45 brass but did use a spend .44mag spent brass ;{) brass measured several New - 3.337” Fired - 3.349” Sized - 3.348” So I’d say only bumped back .001ish Is that what you were looking for? thanks

    Don’t know what reamer dims were but I’d guess similar too yours.

    Numbers are right but as I said there is a slight taper from mouth too shoulder. I’m going to punch primers and anneal a few too see if they size with straighter necks.

    OK, only two rnds once fired reloads thru the magneto speed but if it’s true it explains the high pressure. 1st rnd, 3128 FPS, 2nd 3123 FPS, scary shit! Remember the new brass loads avg of 2975. I’m sure somebody with the right program can figure approx chamber pressure. Not sure I even want to...

    A puzzler for y’all...

    Yea, never even paid attention to the differences when I was measuring those and punching numbers. Just double checked and they are right down close too the shoulder. At the case mouth new and fired loaded brass both measure .338”. No donut but there appears to be a slight cone type thing going...

    New brass loaded - .338” Once fired loaded - .342” Once fired empty resized - .337” Twice fired empty unsized - .341” new and fired loaded rounds same length per Hornady comparator. I’ll try and get out with the magnetospeed tomorrow. Got two rnds of the once fired loaded I didn’t shoot.

    Brass was vibratory cleaned with walnut media. No stainless tumbling. I’ll anneal and play around with it. In the meantime I do have 90 some rnds of the new brass left that will shoot great.

    Bullet slips into the fired case with minimal pressure like you would expect. Id of sized brass runs .306-.307. I typically anneal every other loading but may punch a few live primers out and anneal a few too see what happens. Being Lapua brass I wouldn’t expect hardening issues from one firing.

    Wow, thanks for all the responses. Pressure signs are severely cratered and flattened primers, heavy bolt lift and very light ejector marks. The first rnd of once fired recoil was enough more than virgin it shocked me. I actually went back to the house, pulled bullets and verified charge...

    A puzzler for y’all...

    This one has me scratching my head... I acquired a 300NM last winter, ordered a box of Lapua brass and a batch 230 Bergers. This thing shoots nearly one hole at a hundred with 96.5gr of R50, no pressure signs. Shot a group at 325 that measured just over .750” with the new brass. I am tickled...
