A while back, I decided to try something less temp sensitive than my tried and true load using a 130 gr Ballistic tip and IMR 4350.
I went to the store trying to decide whether I'd buy IMR 4451 or RL 16. My decision was made for me as they only had the RL 16 in stock. I really like the RL 16!
I know that doesn't help, but I don't think a lot of 270 win shooters have tried that powder. I think you are good to go with data you have and I also think you will love that powder. I've read tons of good about in in 270 win.
