[QUOTE="65WSM, post: 645081, member: 9551"] I have a couple of hundred rounds of load development work with the .270 WSM in a Winchester 1885 High Wall (Miruko). I have focused on the 140 and 150 gr ballistic tips an 140 ABs. The .277 140 Accubond has a BC of .496. That results in 6 or 7 inches less drop at 400 yds than my 6.5 WSM or 6.5 X 284 with similar bullets. I need some help with 150 gr B'tips or other 10 twist heavy bullets. What powder are you using? I just tried a compressed load of Magnum with disappointing velocities and performance. I have tried Retumbo (which is the answer in the 6.5 WSM) Reloader 25, Winchester 780, MagPro, 4000MR. and the best I get is 3110 with a heavily compressed load of 4000MR.:rolleyes: MagPro is magnificient in the 270 WSM with 130 and 140 gr bullets. I can get 3300 fps with MagPro with 140 gr bullets and still not use as much powder as the book says is max. lightbulb [/QUOTE]
