    300 Norma Mag

    Sierra Matchking 230 according to my notes 2970 with Retumbo but settled on a load around 2895 2965 with H100 but settled on a load around 2922 Looks like I'll have the 250s right around 2940 with no pressure signs up to 2970, but no need to go further.

    300 Norma Mag

    It might have something to do with the bearing surface of the A-Tips. I was very surprised as well as I was running into the same issue with sierra 230s. I'd say give em a try and work up like I did watching for pressure signs. And use good brass. I just ordered 200 more of the A-Tips. They...

    300 Norma Mag

    Wasn't going to post this...but since you asked... This is my 8 twist 28" 300NM shooting 250gr A-Tips with R33. I am steering clear but you might have better luck.

    300 Norma Mag

    I'll have to wait until I load more to measure COAL. I measure to the ogive and was seating 20 thou off the lands. I never measure COAL but will when I get the next batch loaded up. However, my next batch will be seating depth on paper to check for groups so it will likely change from what I...

    Maybe try Peterson or Lapua brass and the Federal Primers. I'm a big CCI fan but did not have luck with the CCI 250s. Never tried Norma brass so thats where I would start if your primers are working good for you.

    300 Norma Mag

    Not sure if it matters but I have an 8 twist barrel at 28". Barrel was cleaned and stripped of all copper fouling and I shot 5 foulers before shooting the string above. What brass, primer, and powder are you running?

    300 Norma Mag

    I thought so as well. I was hoping for 2850 so I was happy to get those speeds without pressure signs. At 2950, I should be able to dial to 2800 + yards without holdovers and a 100 yard zero. Happiest I've been so far with my 300NM. But...still need to see how it groups on paper and what kind...

    New Nightforce ATACR Turret caps?

    What is everyones level of interest in a custom turret that has 0-36mil markings (three rows) and what would you pay? These would be made from blank factory NF caps that are done professionally ...not stickers.

    Era Tac adjustable mount?

    They are very good and repeatable. I tried both the elevation adjustment and removing the mount and reattaching it to the rail and it was always within 0.1 Mil. Another option is to keep your existing mount and get a Charlie.

    Anyone else had this problem with their kestrel 5700

    I think so but try it for yourself. Set up a profile for a G1, G7, and AB Custom and see which one works best for you. Here is some reading material... http://appliedballisticsllc.com/ballistics-educational-resources/custom-drag-curves/

    Anyone else had this problem with their kestrel 5700

    Ya, I’ve had a similar issue. Transfer everything to your Kestrel, remove the app, and reinstall the app. Transfer everything back over. Should fix you right up. BTW, why not use the custom drag curve?

    The new 33XC & 37XC cartridges designed by David Tubb

    Any chance you guys running 33XC and/or 37XC can put some load data up? I'm looking to see how well you are able to keep your SD and ES down with the longer cases and long strings of fire.
