Personally I wouldn't bother (just my opinion)...the Grendel doesn't produce that much recoil. Although, that being said, I have one of Warped's Ti m.b.'s (very lightweight).

Another awesome bullet I wouldn't rule out would be the 156gr Norma Oryx, which is devastating in penetration and expansion, even from lower velocities. I saw what it can do this past winter on an unbelievably large rabbit, and it left a 4" exit on him out of a 6.5 Swede going pretty slow.
LRRPF52...any chance you can get that recipe for 139 Scenar?...I'm definitely interested in trying the Berger 140 VLD and that should be close. Never considered heavier, but the 156 grn Norma Oryx sounds intriguing...
