RE: Your opinion on best .270 load for long range.
I don't shoot a 270, but I do shoot a 270 WSM. So take my advice with a grain of salt.
When I bought my 270WSM in 2002. There wasn't much load data available, So we had to play with a lot of loads over chrony's and traded info with others.
I found that the 140g bullets were not that much slower than the 130g bullets, IF you used the right powder. The difference in velocity was more than made up for
in down range energy because of the better BC of the 140g bullets. But the jump to a 150g bullet slowed things down enough that they didn't retain more energy than
a 140g down range. For me the 140g bullets had more energy than a 150g at 300 yards and shot almost as flat as a 130g. It was the best choice for me.
I used Barnes 140g TSX bullets
In your 270 WCF, I'd try the 140g Barnes TSX over RL-22. The Barnes manual shows that load at 3112 fps vs most of the 130g loads at 3130-3150fps. Of course you will need to see if the RL-22 load will group in your rifle. You didn't say HOW LONG RANGE you were looking for. If you choose the Barnes TSX, make sure that you have enough velocity at the intended range to mushroom the bullet. If you start a 140g TSX at 3100 fps it will still be traveling 2000fps at 600 yards. I wouldn't consider using this load for 800+ yard shots. You bullet just may pencil through. Of course I wouldn't consider shooting that far anyway.
I shot a 25-06 for a lot of years. I used the Nosler 120g Solid Base and Partition bullets depending on what I was hunting. I can't tell you how many deer and at least 7-8 elk fell to that gun shooting Partitions. If you don't like the Barnes TSX, I'm sure a 130g or 140g Partition would do just fine. The 130g bullet has been the standby for the 270WCF forever.
