270W Ackley improved. .270 fans, come on in.

Anybody shooting a 270w improved?
How about a .270 fast twist barrel running the 160grn+ stuff?

Chime in if you have either one, all the details are welcome.

Just bought some N.O.S. CH 270w improved dies off ebay for an ok price. I already had new brass and a decent stash of .277 pills. Heaviest are 145eldx.
Not sure if I want to go with the 160gr+ stuff and a faster twist.

Any constructive input is welcome. Thanks.

A 140 gr. Berger Classic Hunter, punched thru BOTH Shoulder Blades & Hides of, a small Bull Elk,..
Ka-Pow,.. Hooves in Air with, a 1-10 twist, Tikka in .270 WSM at, 3,173 FPS average Velocity ( Shot was at, 115 yards )
The 140 Berger, is still going OVER,.. 2,000 FPS at, 800 Yards ( Plenty enough "Range", for where I hunt Elk )
You'll get another, couple Hundred yards out of, the 165's -170's in the 1-8 twist .270 imp.
But personally, I'd build,.. a 7 MM Magnum of, some sort,.. for the "Better" BC's
If I wanted / needed, "More" Range, I'd go, 7 PRC with,.. 175 gr Elites / ELD-X's,.. like My son did.
My 2 Cents

270 WSM is about as close as we need here in NW Montana.
Very accurate and hard hitting with 140 AB / H4831sc

7mm gives you better bullet selection, but since you have some components already I think you'll be happy with the 270 AI. There was a guy on LRH that had one and really liked it. It's not much different from the 280 AI which is an excellent cartridge. I had a 270 WSM built a while back, and kinda regret my decision to go with a 1:10" twist (and a .277 caliber, lol) The rifle is very accurate but I wish I had gone with a 1:9 or maybe 1:8.5 so I could stabilize some heavier bullets. I shoot 150 grain Nosler BTs at 3100+ and they have served me well. There is just not much bullet selection for the 270s once you go heavier than 150 grains though. Berger makes some and now Nosler, along with some mono metal bullet makers. Depending on what you want to do with it, and what distances you want to shoot, the 145-150 grain bullets might work just fine. The 270 AI doesn't have enough horsepower to really push the heavy bullets fast enough to make a huge difference at long range anyway so 150s might be about perfect.

I appreciate the input yall. I'll just stay 10 twist. That would also work better with the 110gr bullets I've got.

I put out a WTB ad for a reamer. I like vintage reloading swag, getting the box was a bonus.

Please keep us updated with the performance and loading details. Always like the .270 but never did the AI but wish I had of.
