Forgot to mention, I also have some 180 Bergers also. VLD's an hybrids!
I load 180 VLD with 68 gr H1000 out of a 26 inch Brux barrel
I only get 2900 FPS but am very happy with the accuracy.
Oddly the best I could get out of the 168gr Classic hunter was about 100fps slower bout 2930ish. Like another said about the short bearing length is my guess to heavy bullet more pressure, short bearing surface less resistance. When I was working it up I did run my load up to 71gr and it was definitely hot, and didn't shoot as well either.2900 is about what I figured I would end up shooting when I decided to go with the Hybrids. I have read from a few guys on here that their go to load is either 69-70gr H1000 or 70-72gr Retumbo for the 180's. For you guys getting 3000fps, that is awesome! I was under the impression that was an anomalie rather than the rule. Seems most guys here are having pretty good luck at 3000fps. I will cross my fingers that mine ends up there. I will be using H1000 as that is what I have righ t now.

Was trolling this thread reading up on some data and thought I would revive it with my most current results. My final load ended at 70gr H 1000th .01 off the lands with 215M primers and winchester brass. After this the bolt got pretty diffiicult. 70 had the best accuracy over everything else for me and no signs of ejector marks or anything but a half gr heavier and it was too much so I quit there. I am getting 1/2 inch at 100.
I don't have a chronograph so I am doing it the old fashioned way. Gonna move out to 300 next and see how it holds up. Not sure what velocity I should use to get me close but I should know more after getting out to 3 or 400
Let us know how that load turns out. I was shooting 71 grns of Retumbo with the 180 VLD's and Hyb's, but backed down because the loads were making my Win/Nosler Brass primer pockets loose. no sticky bolt, but slight ejector marks.. Speed was at 3068 fps. I now use 69.5 @ 2990 fps. I plan on working up slowly to see what load I can use where my primer pockets will hold. My VLD's are more accurate than my Hyb's, thus far.
