    Watching Wind Flags

    You might try using an anemometer at your bench to give you a sense of general wind effect. I use a Kestrel (brand) I bought to shoot PRS rimfire on big open ranges. I have it outfitted for variable wind direction and on a small tripod. It connects to ballistic software on my iPhone and iPad. It...

    Bullet choice strictly for 100 yards score matches.

    You might want to try out the 68gr HPFB by Ammerman Arms. It seems to work very well at 100 yards in 6mm with N133 & IMR 8208. Also the 80 gr HPBT Dominator by Barts Bullets with N135 works well in my 6mm 12 twist. Have not used Barts 68. Good luck and have fun developing your load.

    6mm Grinch case capacity

    Pete, I am using a 68 grain Ammerman HPFB over 30.0 grains of N133 which pushes it to about 3380fps. It has not lost its tune yet (few 100 rounds). I am now experimenting with an 80 grain Dominator HPBT (Bart's Custom Bullets). I am pushing it pretty fast over 31.0 N133 (barely compressed)...

    6mm Grinch case capacity

    Thanks for your suggestion. I'll start at 30.0 and see how they do. Plan to load a few today and maybe get to the range this next week.

    6mm Grinch case capacity

    Yes. Dominators are back. I'm going to load some with 31.0 of 8208 as per SteveH. I think they will perform well at 100 & 200 for me.

    6mm Grinch case capacity

    Happy New Year to all! The 6mm Grinch has performed well. The Ammerman 68s with 30.0 N133 and .002 off in Lapua brass did well at 100 and 200. Hope to start 2024 using some 80 grain Dominators (Bart's Bullets) with 8208. I scored two cans of it. I plan to use SteveH's recipe 31.0 - 31.5 plus...

    Wipeout

    Kroil (creeping oil) works pretty well on the carbon ring buildup. Soak the throat area, let it sit overnight if possible. Then push it out. Simple. Used it for years with good results. Carbon ring buildup can affect accuracy, especially in smaller calibers. The most noticeable is 22LR and tight...

    Garmin Xero® C1 Pro Chronograph

    Bought one and I am impressed. Really impressed. Set up time is about 10 seconds. Smaller than a cigarette package (w/o tripod). It comes with its own, btw. Has yet to not record a shot. Downloads data to smart phone or tablet with a free app. Smart phone can export data to a spreadsheet...

    6mm Grinch case capacity

    Thanks for info. 8208 seems scarce just now, as can't find any. Would like to use it if I get some 80gr. Your recipe is one of the better ones. I settled (for now) on the 68 Ammerman, over 30.0 N133 @ 3395 fps, .002 off the lands. Had 10 rounds, so I decided to shoot for score. 10 10s 8Xs (5...

    6mm Grinch case capacity

    I finished testing loads for now. My Grinch (12:1, .268 neck) likes 29.1 - 29.2 N133 with the 68gr HPFB by Ammerman. Best group so far is 0.110 (5-shots) with others about 0.120-0.140. Using a Sightron III 45x45 with dot. It seems there is no difference in group size between 004 off, touching...

    6mm Grinch case capacity

    My scientist friend calculated the case capacity to 30.90 grain N133 at the neck junction. My calc was 31.66. But I probably have the Shoulder Frustrum Volume off. I will use his as it is lower and he has infinitely better math skills than I do (plus access to some really cool measuring...

    6mm Grinch case capacity

    A friend (scientist) measured five of my fire-formed cases and determined their capacity as 36.59 grains of water. This volume can be used to calculate and develop loads for many rifle powers. The process requires some calculations but are not difficult. Subtracting the case neck volume (~4%) by...

    6mm Grinch case capacity

    Does anyone know the case capacity (grains of water, cubic inch, cubic cm) for the 6mm Grinch? I am developing loads for mine (1:12) using N133. Would like to know so I can calculate potential loads. At the moment, 28.0 N133 produces a nice results at 3113 fps as does 28.2 N133 at 3143 fps.
