Anybody know what powder is used. I would think Vhita. I weighed 2 loaded and 2 empties and subtracted the diff and came up with 88 grains powder. Shaking a loaded case you can barely feel some powder movement. Playing with Quickload I found the following. OAL 3.605" my measurement. CIP max press 60916 V V N160=3021 fps @ 69527 psi load density 108% V V N165=2951 @ 63033 ld 104.6% V V N170=2700 @ 46260 ld 104.6% V V N560=3058 @ 61403 ld 101.3% V V N570=2703 @ 39431 ld 98.2% Chrono'd 3 shots yesterday Hi-2958 Lo-2934 Av-2949 Es-24 Sd-13 Looks like the N560 load is closest for volume and not to far off on vel. and slightly over press. N165 was really close to chron'd vel. but press is high. I'd like to be able to duplicate this load. PM'd the Lapua guy haven't heard back yet.
