Yesterday I shot at the Oklahoma City Gun Club’s 600 yard event. This was their last 600y prone match for the year. Well run event as always. I used a different combo for each of the three matches. Same bullet – 155 Lapua Scenar, Win brass, CCI BR2 primers, seating depth @ 2.281” ogive length. Using JBM Ballistics – Trajectory information and only changing velocity to match my moa come ups, I logged the following:
• 45g RL15 @ 14.0moa equals 2740f/s
• 45.2g H4895 @ 11.50moa equals 2980f/s
• 45.0g H4895 @ 11.75moa equals 2950f/s
Does this match up to anybody else? Rifle is stock 5R 308 with 11.27 twist.
