Thanks for the input guys
My defining trait, beside talkin' too much
, is loading for maximum
velocity and accuracy. I'll sacrifice just a little accuracy, maybe as much as 1/2 MOA, for velocity. Thus I get familiar with which powder gets to the pressure limit first.
4350 is a great powder in the 270 Win. I used it for 2 decades w/the 130 Speer boat tail when I couldn't get N205 any longer. I shoot my 270 Win w/130s and 140s at around 3200 FPS MV. Actually its right at 3190. This is what I worked up with N205 and stopped at that velocity just because it was a good number, shot very accurately and case life was forever.
With 4350 and the same velocities I had to FL resize, I partial neck size for increased case volume, after 4 shots. Cases still lasted forever. But it was a max load as any more powder and it was tough to get the bolt open.
With RL-22 I load to the 3190 velocity and never look back. I switched to Nosler ballistic tips as the flat tips on the Hornady's from the magazine drives me nuts.
The 130 and 140 Noslers shoot lights out and are deadly to beyond 640 yds. That's all the farther I've shot it.
As far as temperature sensitivity goes, from summer and 80* temps to winter teens the chrony says I lost 130 FPS. I don't change charges for winter and have done in lots of yotes out to 400 yds. I have less faith in the temperature sensitivity of the cheap chrony than I do in amount of the powder's sensitivity.
What winmag says is good. I'd try some of his suggestions too except that the ol' Winny is steady as she goes and am like DANNY-L who BTW has a great load there.
If ya really want some steam try a Nosler 150 ahead of 87 grains of 7828ssc for a little better than 3600 fps. Deadly at 1400 yds
Which is another reason I have no reason to soup up the Winnie.
