Spent this evening loading up some test rounds finally. Nothing to scientific, just a full case of RL16 which is 41.5gr to the bottom of the neck. A small crunch on the longer 143gr eldx but no real compression or seating rebound. No pressure even on the heavier bullets with this full case charge so its the case volume that restricts any further velocity with RL16 however it still leaves the max charge of 42gr of 2209 velocity in its dust.
This test is more a max speed test on each brand and weight and will test the extreme spreads. I'll run them over the chrono and put them on paper in the next couple of days.
The projectiles to test are:
130gr Hornady ELDM
136gr Lapua Scenar L
130gr Sierra Tipped match king
139gr Lapua Scenar
143gr Hornady ELDX
130gr Berger VLD Hunter
123gr Lapua Scenar
123gr Hornady A-Max
