    Worked up a load for 150gr Barnes TTSX

    I decided to switch to Barnes copper bullets this season. I also wanted to document my experiences because there’s not a whole lot out there on other forums besides unanswered questions. I previously used Nosler 168gr Ballistic Tips, so I chose Barnes 150gr TTSX because of similar bullet length. 150gr TTSX: 1.3” 168gr BT: 1.307”. Very close despite the weight difference

    Here’s a comparison. Left to right: Nosler 168gr Ballistic Tip, 150gr Barnes TTSX, 168gr Nosler Custom Competition, and 165gr Sierra GameKing




    The Barnes manual says the range for these bullets and my powder of choice, Reloder 15, is 44.0 to 48.0gr.

    I started a tad over mid way at 46.5gr, increasing in .3gr increments.

    Host rifle is a Mossberg MVP 7.62 TALO edition. 18.5” 1:10 twist medcon barrel. Optic is a Vortex Diamondback HP 4-16x42. Innovative Arms 7.62 suppressor

    46.5gr showed no pressure issues and was about 1.5 MOA.

    46.8gr showed no pressure issues and was around 1MOA

    47.1gr showed a TINY bit of primer cratering but very tiny. Group was excellent for copper hunting bullets.



    I accidentally wrote 41.7 instead of 47.1 and had to scribble it out. Derp derp derp

    47.4gr opened up to 2+ MOA and cratered the primers pretty good.

    I didn’t bother firing my 47.7gr load because of the last ones. I need to pull them down and recoup the bullets.

    I might test Varget or 8208XBR at another time. For now...we’re in business with 47.1gr RE15 at 2.810”
