    Links for PRS/Bipod Shooting

    The snipers hide online training covers this very well. How to square up, load different types of bipods, drive the rifle, etc. My wife was very high achieving shooter for small bore .22 I shoot PRS style matches, and not nearly as successful as her. Our prone positions look nothing...

    Muzzle Brake Gas Dispersion and LabRadar

    Not exactly an answer to what you asked but hopefully helps. I set my lab radar about 8 -12 inches left Of my stock /chassis somewhere about even with the bipod. This seems to work very well. It picks up all my shots. If I get too close to my brake up toward the front of the barrel, gas...

    DOPE shifted during match

    For me, High Impacts 1) Weak position on a barricade, high impacts vs driving the bipod hard in prone 2) New Barrel speeding up. My barrel speed prior to match at 2850 I noticed high impacts and got 2875 after the match, now its 2900 at 400 rounds 3) Temp increase from morning to afternoon...

    CCI BR4 primers misfires

    Agreed, I think it is a combination of what you mentioned, 1) the firing pin seating the primers for .002 combined with 2) a few extra thou of headspace on new lapua brass absorbing the firing pin strike.

    6.5 CM Berger 130 Gr loads

    Yea my chamber is long, which I'm guessing is why i only get 2805fps with 42.4gr of 4350. You may see better speeds / more pressure with less powder. Let us know how it turns out!

    Clocked, I run 130 Berger AR Hybrids *42.4* gr H4350 Lapua 6.5CM Brass CCI BR4 Primer I get 2805fps with zero pressure signs. This is probably on the slow side but it shoots 1/3 MOA and my speeds always fall within 10FPS when I chrono. Tight groups and small ES..... DONE On the ES...

    What was your biggest “aha!” Moment as a beginner?

    1) Getting off the bench and realizing how much BETTER i can shoot prone. 2) Getting off my belly and realizing how much there is so much to learn from alternate positions. I love getting in the back yard and building positions on stuff around the house and watching my wobble decrease every...

    Advanced Marksmanship POI Shifts From Different Surfaces

    Thanks for your reply, I guess ski feet is a bad description. Its a sako bipod, claw feet may be a better way to put it. They grip hard on grass.
