Re: What is the real BC of the 240MK?
29 inch 30-378, throated so the boattail junction is just above the neck/shoulder, crammed .005, H50BMG 107.5 3130, 109.5 3170, 111 3220 (slight marks) Marks aren't as bad as some factory ammo I shot when it was a regular Accumark. Retumbo starts showing marks at 103 3185.
I had just enough time to launch 3 of the H50 107.5's (3130) at 500 tonight. Had some mirage (riverbottom flat) but I usually do not get much wind affect vertical here. Although I was seeing at least an inch vertical jump of the bull due to the mirage, I was pleasently surprised with a 1.8 inch three shot, one of which was a fouled/cold bore. Scope was doped for 6.5 MOA and POI center was 1 1/4 inch high, 2 inches left. I did see the left push too but held center to see how much these big bullets would push.
Needless to say I'm quite pleased with this inherently inaccurate Weatherby.
