my 169.5 .277 wildcats @ 3015 have a 38" drift @ 1000 with a 10 mph crosswind @ 5000' I'll stay with the 270

I just noticed that you said at 5000 ft. Using bulletflight fte Berger 168 at 3100 fps with a 10 mph cross wind has a wind correction of 37.5"

I went to the appliedbulisticllc web site on CRNA's post I think the 37.5 sounds closer than the 62"
mine is calculated on Exbal
I think you would be good with either berger 168 or 180 also the 165 matrix or 169.5 wildcat .277 but I would use a 1in9 twist on the 270.

Re: Favorite bullet weight for a 270 & 7mm

+ 1 with 270 lefty all the way. my 300wm is going to the closet. I love the fact that i can load up the 165 or even the 175 matrix and have a legitimate long range rig that will not brake my bank to load for. 66 grns of retumbo. Awesome, I will get more loads out of my powder and have more downrange energy than my 300. Sign me up. Can't wait until spring to get my rifle back.
