    Picked up a dasher ,26" x8twist and Whidden dies and need a place to start. I have most of the popular powders and lots of Berger 105's and SMK 107"s . Thanks Gary

    I saw that but thought there might be some updates on the 105/107 bullets

    I have been shooting 115 DTACs for quite a while but just tried some lighter stuff this past weekend. The 105's jammed 0.005" with RL15 shoot great for me; 3/4-inch at 300 yards.

    Lapis brass, BR-4, H-4895, 103VT’s start at the touch point. 31.5grs of powder and work up. 103’s and 105’s shoot good around 3000-3010.

    RE15,Varget and H-4895 are you most often used powders. CCI 400,450 and BR are primary primers. Roy Hunter, Barts and Vapor Trail all make exceptional bullets. 105 Burgers are also a good choice, but need a little more sorting. Property prepared Lapua brass is the standard. It should not take you along time to figure it out. Shoot what the barrel likes.

    How much r-15 for the 105's? What velocity?

    WOW!!! Over 34 Grains RL 15 with a 105 class bullet?? That seems pretty stiff. I have a bunch of dasher tubes and I rarely get over 33 G.

    I guess it is true....every BBL is different.

    This is my first Dasher barrel so I don't have any real reference. It's got over 2,200 rounds. No pressure signs for me. The chrono velocity to align with what others are shooting and what Quickload indicated should be a close-to-max velocity. I understand RL15 is temp sensative and it was around 40 degrees F.

    Are you sure about this all?
    Is that with 103-108 class of bullets?
    If so, it sounds more like RL16 data for 105-class bullets.

    Anything much over 33.3 grains of RL15 would be excessive in pressures in every 6Dasher barrel I've ever had.
    Have never heard of anyone at the charges your speaking to with RL15 from 105 class bullets in a 6Dasher.
    Just saying.....

    I'll certainly defer to you guys on what is typical. I don't have the experience you do with the Dasher and almost none with RL15 in it.

    I appreciate the caution and deleted the post.
