    Expander Mandrels

    I like the idea of imbedding the graphite into the brass in the neck. Should make long term storage better by keeping the bullets from adhering to the necks and stabilize neck tension. Stored rounds should have same tension as newly loaded ones.

    Expander Mandrels

    The Lee Collet Die is what I use to resize the necks on my cases. Use a Wilson F/L bushing die w/o the bushing to size the rest. I like the Lee because of not having to lube the necks and size the neck 1 time and through. Instead of sizing too much and having to expand to get the size I need.

    Absolutely. The smaller the increments in size change the better the outcome.

    Expander Mandrels

    You won’t be working the brass any more with the mandrel than you would with the expander button in the die. As far as concentricity goes if the brass is not the same thickness all the way around, it will expand more in the thin spots. Annealing makes the brass more pliable and expands more...

    6.5 Creedmoor

    I’ve never tried the Match Burners. I use Hornady BTHP, a very consistent bullet, Sierra and Berger. What kind of rifle do you have and how long have you been reloading?

    6.5 Creedmoor

    I don’t know about your situation but I’ve had mine do the same thing after letting the barrel cool. Maybe your ammo got heated more. I shoot at my house so I’ll shoot about 10 rounds then stop to load some more letting the barrel cool. So my ammo never gets heated up. Since you are only...

    Did you let the barrel cool between targets? Or it could be the barrel dirtier.

    Wormydog, That’s some good shooting. That is a very catchy user name.

    Expander Mandrels

    If you neck turn your brass that would be the way to go. If you don’t NT then you would be over sizing some brass and maybe under sizing some. The thickness of brass in the neck area varies between brands and even different lots.

    6.5 Creedmoor

    I’ve never used the Redding one but I have the Hornady Micro adjusters on my dies and it definitely helps with precision adjustments. I adapted one to my Lee DL seater and when I find the setting for a certain bullet at a certain length, I can just put it on that setting and go. With the die...

    Expander Mandrels

    Shot these a couple of weeks ago. Temp in the 90’s and humidity in the 70’s.

    Ladder test questions

    If you’re rifle is new and unfired, the loads you find may change after a couple hundred rounds. Be sure to give it a very good cleaning before you start. The barrel break in process is aggravating but I do them regardless. Don’t know that it helps but it definitely doesn’t hurt. I would get...

    Ladder test questions

    You can use just about any commercial round to get it close but the different loads will move around on the target. Some will hit low left and change to high right or vice versa. Like above what you are looking for is consecutive loads that shoot to the same poi in relation to the aim point. If...

    Concentricity, accuracy, and neck turning

    I have a 700 Custom KS in 7mmRM and it has a very short freebore. I didn’t like the fact that new 7mmRM brass has to stretch .017 to .022 to fit the chamber the first firing. So I made my brass from 300WM brass and turned the necks down to all the same. I also use the LCD and get very low...

    Expander Mandrels

    I use a Wilson F/L Bushing Die without the bushing for the case body and a Lee Collet Neck Die. But I also neck turn my brass. Get extremely low sd and es.

    Something Wrong With Reloads, Can't Figure Out Why? Need Help!

    You try those 142 SMK's and you will throw rocks at Red tipped bullets. Your 7.5 twist should like the 150's. My rifle will not shoot any weight (130,140,147) any where near as good as the Hornady BTHP's. Glad to hear you got it figured out.

    Loose primer pockets on Starline

    3.6% difference in water capacity = 1.5 grains of powder. If primer pockets are getting loose, there is pressure. Have you miked the case heads to see how much expansion you are getting? My primers are flat with 41.5 gr of H4350 and 140's in my bolt gun with Starline LP brass.

    Ejector mark ?

    That's good advice about the case getting longer before it gets shorter. Hang in there and don't get discouraged.
