Very good observation on the sectional density, we've pushed the 130's out to 500 yards and that's right were things are getting sketchy and we've started loading the 140 Berger at 3050's and they are GTG in that range. Interesting this is the 165 start crapping out at the same range, I put a lot more faith in sectional density than energy figures!!!!
I think the 150 Matrix should be a good bullet for hammering elk, I was going to order some but after finding out the 165's stabilized and we put a dozen on elk there just isn't anything else I would put in a 270 for elk unless they wouldn't stabilize. I've found them very easy going to load and to top it of every rifle we have loaded them in has shot them better than anything else, my buddies shoots in the .2's at 2835fps with the 165 and destroys elk!!!
I would push them harder but at 2900 they'll rock an elk gun)
Kudos on that. I think with similar velocities SD is as good a measure as any on penetrating ability, but if you crank it up, say in a 7mm ultra, all bets are off. You may get another 100-200 yards of usable range, but the bullet may get soft on you.
I shot my longest two offhand (no bench or bags) kills over 600 and over 700(yards) with a 7mm ultra using a 140 sierra fb and rl25 with a 215. Didn't gps those shots, and they were most likely farther as I did take other measurements and round down. That rifle was a laser and if the barrel hadn't gone, I'd still be killing with it.
