    6 UM or 6-7PRC?

    I’ve got the bushing that’s .003 smaller than loaded neck size and then I’m using the Sinclair carbide mandrel. I’ve always had good luck with this combo, but there is a good bit of seating force. Have you had good luck with any other mandrels? I’ve used some other brands before but since they...

    6 UM or 6-7PRC?

    Thanks for the info. Any idea how low I could go on powder charge and still get a decent fire form? I’d like to take it easy on the barrel if I can for the first 100 rounds.

    6 UM or 6-7PRC?

    Got my 6-7prc out on the range this morning. Loaded up 65grns n570 with 115 dtacs. Seems like the rifle is going to be a shooter. First 3 shots out of the gun with a 3/4” dot for reference. Velocity was 3130 average over 8 shots this morning. Going to run the velocity up once all my brass is...

    Density altitude and sight tapes

    This is off topic from archery, but what apps do you use with density altitude? I’m trying to figure out how to use DA, I don’t see it as an option in most ballistic apps.

    6 UM or 6-7PRC?

    Got in contact with hornady, they sold me a 6mm inner sleeve for 9$ shipped. Hard to complain about that. Great service from hornady! They were the only die maker I talked to that didn’t act completely put out I was “bothering” them with my request.

    6 UM or 6-7PRC?

    So I bought these hornady dies and the 6mm stem and the outside diameter of the 6mm stem isn’t the same as the 7mm stem. Same problem I’ve had with Redding and all the others. It just bounces around in there loose as shit. Seems like there will be concentricity issues

    What micrometer seating die is the go to for this? Is there a 7prc seating die out there that will take a 6mm seating stem?

    Seating Die with interchangeable seating stems

    Is anyone aware of a micrometer seating die brand that you can interchange between calibers? I need a 7prc seating die that will accept a 6mm seating stem.

    6 UM or 6-7PRC?

    I ordered mine January 5th. Mines just a rebarrel on a tikka action with the full action mods and nitride. They called me last week and said they were ready to start. I’m doing black cerakote on the barrel, nothing fancy. I was told I’d be 12 more weeks.

    What’s going on with the Factory Hornady 7 PRC ammo?????

    Pretty sure original load was rl-26, they are now using a superformance or staball hd sort of powder. It’s a ball powder.

    Barrel Chop Screwed Up Accuracy

    I’ll have to check when I get home but I think I’m around 24.9 grns Varget, seating depth to mag length can’t remember the length off the top of my head, lapua brass, and 77tmk.

    Barrel Chop Screwed Up Accuracy

    Had my tikka 223 cut and threaded by a well known gunsmith. It is has 17” of exposed barrel. It totally screwed up the accuracy. Anyone have this happen? Previously it loved the 77tmk and smk, threw them both in about a 1” 10 shot rapid fire group. Now it groups around 2+ moa and pretty random.
