Re: 270 WSM best combo?

I am interested in long range hunting. The 140 gr Accubond in .270 has a BC of nearly .5. The only competitive bullet is the 140 Berger Hunting VLD. The 150gr Ballistic Tip has the same BC as the best 140 gr bullets but will never start out as fast. To shoot a higher BC bullet you will need a steeper than normal 10 twist barrel.

MagPro produced 80 to 110 fps (barrel length) than any other powder I tried. I have tried VV N-560, Alliant 4000MR, Reloader 25 and Retumbo. 74gr of Magpro would get to 3300 fps in a 28 inch barrel of a 1885 falling block. The other powders were closer to 3200 fps. Let me know if you have found a powder that produces more velocity than MagPro.

I shoot the 165 and 175 Matrix and they are fully stable to 2000 yards at 5600ft elevation with a 1-10 twist, the 165 is fully stable in our 270 wins also. Lots of guys shooting the 165 Matrix at much lower elevations in a 1-10 twist. They are worth a try for the increased performance past 800 yards.
