    6.5 Creedmoor

    If you can't get the VLD bullet up tight or into the lands, I'd change the bullet. You have a bunch of free bore in the barrel. Try a 140 ELDM with H4350 at .020 to .030 off the lands. The ELDM bullet ogive is closer to the bullet tip and has a longer bearing surface. You should be able to run...

    6.5 Creedmoor

    I have never been able to get the Berger VLD bullet to shoot very good off the lands. (I use the VLD 140's in my CM and the VLD 105's in my BR). I would circle back and seat the VLD bullet up to or into the lands with H4350. It will group. I'd try touching, +.03, +.06 and +.09. Shoot 3 at...

    PRS rimfire director bullies youth shooter at prize table

    I agree, ditch the prize table and do cash payouts to the top 5 winners like NSCA shoots. Solicit vendor/sponsor money and add it to the cash payouts for the top 5 winners.

    Poor precision with competition seating dies.

    I expect the neck tension on your sized cases is inconsistent. If you are using a bushing sizer, I would increase the bushing a thou or so and see what you get.

    Ladder testing translation

    I'd decide on a powder charge that gets you the velocity you want. Load up 3 of each at that charge touching, .020, .040, .060 and .080 off the lands. I'd shoot them at 100 yards. See what looks good and vary the seating depth from there. If you don't see anything that looks good, change the...

    Hornady 4DOF App vs. Kestrel

    I reached out to Hornday in 2021- I have another question for you. I am starting to use the 4DOF program. The program wants both the uncorrected pressure and altitude. Why does it need the altitude if the Baro input is the uncorrected pressure and not corrected pressure? I ran two...

    Hornady 4DOF App vs. Kestrel

    When I was using the app, I didn't link the meter. I just input my environmental data from the meter manually and left the altitude at zero.

    Hornady 4DOF App vs. Kestrel

    The Kestrel is calculating the solver projection based on density altitude it calculates that from the Kestrel meter reading (temp, humidity and station pressure). It doesn't need the altitude input to back into the station pressure because the meter has captured that (the station pressure)...

    Hornady 4DOF App vs. Kestrel

    Points taken. I was only trying to point out that you either have to use a GPS device to determine elevation or rely on a pressure sensor from a device to get station pressure. Either will work. I have used both the 4DOF and AB/Kestrel solver solutions out to fair distances with pretty good...

    Hornady 4DOF App vs. Kestrel

    I think the the 4DOF app calculates the station pressure from what you enter for altitude unless you bypass it and manually and enter the station pressure. Go into the app and enter 0 for the altitude (sea level) and note the pressure. It will be 29.92. Sea level corrected pressure. Change the...

    Garmin Chronograph - calibration?

    I do the same. I shoot at BB 300 PRC/300NM. I start with the the Garmin/LR MV and AB projection and then I center up on the 10 inch plate at 990 on the top of Spears mountain and adjust my MV in AB to agree with impacts at 990. I just back into the MV from the actual come up at 990. The AB...

    New 6 Creed problems with PETERSON brass

    I'm pretty sure it is the same across the Peterson brand regardless of the caliber.

    New 6 Creed problems with PETERSON brass

    The difference is probably the case volume. See attached 6BR/Dasher cut aways. Do the same on your different makes of CM brass, and I expect you will see the same thing. If you want to keep using the Peterson brass and are dead set on 3,100-3,150 FPS I'd try the Vihtavuori 500 series powder.
