  1. 6mm Creedmoor Load Development: Powder Charge

    I would review charges on each side of 40.5 in .1 gr increments, the 42.0-42-2 load appears unstable and shifting. Did you use wind flags ?

  2. To uniform pocket or not, that is my question

    The thing about tests like this, is the actual quality of his brass pocket depth average and scatter. It is too easy to draw bad conclusions on poorly designed tests. Sorry to be critical, but just posting on YouTube doesn't qualify the results as valid and that spread of charges detracted from...

  3. 6mm Creedmoor Load Development: Powder Charge

    With your cross wind and due to its lack of VERTICAL DISPERSION. The target #3 load looks very good.

  4. Lou Murdica's process

    That assumes best accuracy always occurs at a certain velocity. The best competitive short range bench rest shooters may not buy into that theory, they do tend to shoot hot loads. . Having said that most top BR shooters know what powder, charge and bullets the other top shooters use for a given...

  5. 107 Sierra loads for 6BR

    Start with Varget 29.0 and go to 30.0....... shoot 3 rounds of each in 2/10 gr increments and that should allow you to find a nice wide sweet spot. For the initial ladder test I would just seat them all .015 off. With the Sierras the powder charges didn't make near the difference as in...

  6. 300wm tuning help

    Regarding your opening comments, your reloading ideas and process are squared away. I am curious though, with the powder charges your running in the platform you described, what if any are your pressure signs? How flat are the primers, are there any ejector marks on the brass heads? Your photo...

    NECK TENSION

    Bart As usual your insight is clear and to the point. For my 6 PPC, I usually seat so that when chambering, the bullet is pushed to its final length when the bolt is engaged. This seats it into the lands, but not real tight. For me, the PPC is my first foray into extreme accuracy. All of my...

  8. Precision Progressive

    The 3/10 grain in pistol is more when I use the flake powder sometimes. Which does not meter as consitently as Ball, or if you are going fast and rough with the handle pumping them out at 300 rnds /hr (which I do with 9/40/45. I'm not bullseye shooting with my Semi pistols, but more shooting...

    LOAD TESTING and BARREL TUNERS

    NOTES - ADJUSTING TUNERS - MORE THAN JUST SHOOTING GROUPS AND TURNING IT ========================================================== Not sure if these facts will help or confuse tuner users but thought I would post this as I have read articles and watched videos since I began using tuners about 3...

  10. 45cal in 45-70 brass

    What I have in post #24 was poorly written. It was not meant to question the action strength as much as the load data by Barnes. Barnes data is listed as Ruger #1 and Marlin 1895 loads. They state that their loads are tested to 42,000 PSI for the Marlin vs 55,000 for the Ruger. That was the...

  11. ES & SD #'s & accuracy question **UPDATED 7-20-10**

    Re: ES and SD #'s & accuracy question **UPDATED** This is the core thing. Under 300 yards it is far more critical to get the load right so you are in the accuracy node. Map those velocities versus shot placement as much as possible. Ignore the horizontal at this stage for your load...

  12. Welcome to the Reloading Forum -- Introduce Yourself

    Hello, I'm new to the forum here, and so far I must say this is a fantastic place with good people, and excellent advice and information! I love the vast amount of experience I'm seeing here! I've been shooting since I was 6 years old, and reloading since I was about 22 years old. Mostly I...

  13. LOAD TESTING and BARREL TUNERS

    I know of and have never seen any reason to believe that moving a tuner one direction vs the other is directly related to which direction the group will change in except...vertical is consistently the FIRST indicator that tune has changed. You're very close when you see absolute straight...

  14. 6.5 Swede 10 Round Load Development

    I guess I will hang my as a over the fence for a flaming! I have used this method to work the last few loads and it has seemed to work out well for me. I am curious to know if everyone thinks it's luck or if there is something to it. I'm not loading for a bench rest though, a combo of...

  15. Where to go from here? 308 Win with Berger 168 gr Hybrid

    Minimum load for Varget and Berger 168 gr bullets is 38 grains. Maximum load listed for this combo is 42.5 grains. I loaded a single round at each of the following charges (CBTO of 2.228”) and looked for pressure signs o 40.50 95.3% of listed max 2283 fps o 40.70 95.8% 2374 o 40.90...

  16. New 6mm longer barrel life, same accuracy 6mmCompetitionMatch

    Having processed some the recent posts I have a few thoughts regarding the 6mmCompetitionMatch and the process of shooting it and cleaning it. First, when I designed the cartridge I was sure that it wasn't a bench rest cartridge. Simply because I thought that bench rest didn't require barrel...

  17. Accuracy VS velocities

    Bart there is know substitute for actual range tuning for a given yardage at intended range for match considering small groups that is a fact!!! but with that being said life and time restraints get in the way for most of us. i will us myself as a Ginnie pig until this year I have never...

  18. MY .224 Valkyrie and 85.5 Berger Load Development

    Ok I have lurked on here, here and there, I've noticed some here playing with the Berger 85.5 and I thought I'd contribute to the great community here as well. For those looking for more information on the Valkyrie there is a special "Valkyrie" forum and various threads on snipershide, and a...

  19. Accuracy VS velocities

    I like this answer. I believe the big bullets especially the 200 grain plus thirties don't settle till 3 or 4 hundred yards. The targets start to show what your changes do. I can throw a grain or more in a big 30 and not see any change at 100. But at 400 a .2 change can be a lot, at least enough...

  20. How Much Precision in a Scale is Required for Precise Weight-Sorting?

    This is all hand-waving, if F-Class was that much easier than BR, the BR shooters could show up at F-Class matches and clean up. That isn't happening, and here's the reason, which is very pertinent to the whole tenor of this thread: the limiting sources of error are not the same in the two...
