    CCI BR-2's and H4350 worked extremely well in my 270 with the 130's don't have the charge weight memorized. Just a hunting rifle and it was shooting 2" at 300yds all day.

    The main thing about most factory .270s is the throat depth. If you are working with a Remington for instance, you can throw out the max COAL. They have a LOT of freebore and the seating depth of the bullets can be pushed way out there. Get a Hornady comparator and check it.
    For instance I can't get 135gr SMKs within .080 of the lands in my Rem700. That is with 2/3 of a caliber (.185) in the neck.
    Seat those 130s out there a ways and you can bump the max charge by as much as 5% without pressure problems.
    Start low and work up and you'll be surprised.
    My 135gr SMKs are leaving the muzzle at close to 3200! 3180 (avg) out of a 22" barrel is haulin' azz!

    The traditional load for the .270 Winchester is 60 gr. of H-4831 over whatever 130 gr. bullet you want.

    Works great with Nosler 130 gr. Ballistic Tips out of my Sendero. Man I am going to miss that rifle. :(

    My old Ruger 77 loves 130 gr. Sierra Game Kings over a nearly max load of IMR 4350 with CCI primers. Start lower and work your way up. The same load places a 150 gr Partition within 1 inch of the 130 loads at 100 yards.

    40 years of loading the .270 in 3 rifles of my own, and countless others for friends, here's where I'm at today:

    58 grains of IMR4831 (Burns a bit faster than the Hogdon of same number, and I found I could get a bit more velocity on the chrono.)

    Federal 210 Gold Match Benchrest Primer

    130 grain Nosler Ballistic Tip

    R-P Nickel case.

    Out of my Rem 700 BDL Stainless, (pillar bedded), this groups consistently at 3/4" or better, and chronographs at 3150 fps from the 24" barrel.

    If loading for friends, I drop this to 57 grains, since I cannot spend the time on their guns as I did mine watching for pressure signs, chrono spikes, etc.

    A very consistent performer in all M700's, M70's, M77's, 110's, a Husky and even a Parker Hale. I take issue with the statement "over any 130 grain bullet". Changing bullets with the same powder charge is the quickest way I know to get unexpected pressure changes. Nosler Ballistic Tips are famous for increasing pressure, due to their increased length and bearing surface. Partitions can show the same characteristics, and all-copper bullets (such as Barnes) will do the same.

    A Dall Sheep Ram with a 38" curl views me from the wall as I write this, and has no argument.

    Mine too, my 270 is one that has to be full of powder or accuracy goes away
    H4831 and just about any 130 gr bullet does very well if I do my part
