Im surprised you don't neck turn your brass- Im worried about a "donut" forming inside the brass screwing up the amount of grab on the bullet.
Just use an RCBS Pilot/Neck Reamer. When I think a donut is forming, I just size then run this pilot/reamer into the neck. It's designed to replace the pilot on the RCBS Trimmer lathe cutting tool. A touch of neck turning lube, a couple of turns while Trimming, and "donut? What donut?

FWIW, most bullets are seated far enough out that the pressure ring (where the bearing surface meets the boat tail) is above it. Only time the donut is a real issue is when seating a Loooong bullet and you have to stick a lot of it into the case so you can chamber it.

Thats a great idea. I was thinking of buying a .222" reamer to cut down the doughnut when it appears on my .223 loads.

Hey guys, quick question on bullet batch, or lot.
I just opened another box of my 175 SMK and when I went to measure the OAL to the ogive I noticed a .030 difference in the lots. how will this affect the load?
I know I should have purchased the bullets in a larger lot but at the time 100 round boxes was all that was available.

Thanks

I believe Sinclair makes a tool that clamps onto the other end of the caliper with a hole cut out for the primer so the case head rides in "the groove".
Thank you so much for the write-up sir. This should be a sticky. I have learned a lot from this.

However, I would be even more grateful if you were able to find the product you mentioned here. I have always been annoyed by this and even though it generally isn't too difficult to just deprime, I would still like to have this tool at my disposal.

Two problems are possible. Seat using OAL to ogive and you'll have varying seating depths. Seat using OAL, case head to meplat and you'll have varying "jumps".

Of the two, the seating depth into the case will have the least effect on accuracy.

I buy in lots of 1500 or so and just sort by base to ogive length. If I had only a box of 100 I'd still sort and segregate, then use the case head to ogive measurement to seat. That way at least each group of cartridges would have the same characteristics rather than one or two with deeper seating depth/greater jump and another few with the opposite, all while trying to group the 5-10 shots as close as possible (either in group or score).


I've found this to be the cause of my "3 in one hole, two in another hole" groups. The variations cause speed changes which shift poi.

Threads such as this one are what differentiates the HIDE from other forums! Lots of very detailed experience written out in a way that even beginners...like myself, or others with years of experience can read this and walk away with some new found knowledge. Thanks!

Remember that you must readjust the die to touch the top of the new shellholder when changing between say +.004 and +.006. The thickness on the top of the shellholder varies, not under the cartridge. Just changing the shellholder will not change the headspace sizing.
It ABSOULTELY will change the head space and is the entire point of getting the shell holders! Going from a 0.004 to a 0.006 will not becasue you are going backwards. Going from a 0.006 to the 0.004 will. And if it has not then you have not found the correct shell holder yet move on to the 0.002. If that still has not moved it then you need to screw the die in just a touch more and start again using the 0.010 holder.

Hondo I rub it on and run it through the press.

Caccitore I see the shiny ring and can't tell you why it is there but I did not deburr the flash hole. I just cleaned the pocket. Debuting happens from the opposite side anyway. To deburr you would run the tool through the neck.
that shiny ring is from the primer pocket uniformer, the flat part uses the base of the brass to set the depth so that spinning on there causes that ring.

The part I'm still missing is determining the bushing size needed if you don't have a loaded round. I have once fired brass and the bullets, so I just took the width of the brass times two added the bullet diameter then subtracted .002, is this sufficient?

I do not actually have or use something like this I was just told that it did exist. But I did find this and it seems like it would do the trick because it appears there is a recess in the center for the primer to fit even if it was sticking up proud.

I love the pictures, they are easier to "read" than a reloacing book. I've reloaded in the past but not for precision. I'm about to get back into it. Thanks for the info.

Thanks for this write up.. I am using it for reference at the moment and would also like to see this put back as a sticky..
