<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: threetrees</div><div class="ubbcode-body">short survey about bc of bullets for 270 wsm:
company, type, weight - bc
------------------------------
nosler, partition, 150gr (9.7g) - 0.465
nosler, ballistic tip, 150gr (9.7g) - 0.496
nosler, accubond, 140gr (9.07g) - 0.496
hornady, sst, 150gr (9.7g) - 0.525
berger, vld, 150gr (9.7g) - 0.531
ps: yes, those are all hunting bullets and not specifically made for certain ranges ... but it might still be interesting to see which bc you can (easily?) get
personally, i'd prefer to see more into the 0.6 region </div></div>
You missed the best three!!
165 Matrix no solid data but I'm guessing mid to high .600's.
169.5 Wildcat again no solid number but some are using .740 which seems high.
175 Matrix BC on the site are calculated and seem to run quite high but should be in the .700+ range.
There's at least one project on going that will add more high BC bullets to the 270 line up that I know of.
I ran a couple 165's out the other day while breaking in a new barrel and they ran 3054 with easy and a light load of Retumbo, as soon as I get a decent day I'll find a good load and knock out a drop chart for them.
Wildcat or Matrix don't have much for published tested BC's just calculated one's so far. I know Litz has shot some of the 7mm and 30 cal stuff from both Co. but I don't think he has shot any 270.
