    Applied ballistics program problems

    Running iPhone se. AP program has multiple problems. Gives almost twice as much wind as it should. I reloaded the program and it came right but after a while it reverted back to way to much wind. I put velocity of my round in at 2790 but when I go to calculate page it's at 5200 fps. Has other...

    .260 pressure problems.

    Hi tank. Interesting, guys in the club have measured ogive length and Weight of many projectiles. The lapua projectiles are the most consistent weight and ogive length of any of the other projectiles used. Including Berger. I've found them supremely accurate with the right charge behind them.

    .260 pressure problems.

    Thanks aus hunter. I do get my brass annealed and the problems I'm having are with new lapua brass only been fired once. I haven't changed my dies and haven't been doing anything different. Which is why I think the advice re batch powder differences may be the problem. The load info for 140 grn...

    .260 pressure problems.

    Ok thanks. I have carbon cleaner so will keep scrubbing with a bronze brush.

    .260 pressure problems.

    Thanks for your insight. The recommended max load for 2209 is 44.5 so I'm well under and their recommendations are pretty conservative. But I will drop the powder back until I get 2800 fps and go from there. Cheers.

    .260 pressure problems.

    Hi. I have a tikka varmint in .260 that I've been shooting in competition matches.its had probably about 1200 rounds through it. I shoot lapua scenar 139 with lapua brass and br2 primers. I load 44.4 grns of ADI 2209 powder which is the same as H4350 I've been getting about 2830 fps. At a match...

    7mm Rem mag 168gr or even 180Gr tumble and inaccuracy with 8 twist barrel?

    Indeed a bullet will not tumble but only swap ends. It's physics. The heavier part of the bullet will start going first when it becomes unstable and the front will follow oscillating or wagging behind the heavier part. It will look like it's going through the tartget sideways but it's just the...

    260 nodes and velocity

    Hi My friend and I shoot tikka .260s. Both rifles had load development separately and both rifles are very accurate using 44.4 grns of adi 2209 or h4350 which is made by adi. Shooting lapua scenar 139 grn with br2 primers. They go at 2830 fps which is what we both settled on separately. Which...
