Thinking of a .277 for new build?

[6.5shaggy]

I have two 6.5-284s and a regular 284win. I can handle plenty of recoil but not as excited about it as I used to be and I really don't like brakes. I was going to do a 300WSM on a long action but now I am thinking a 270 Sherman, 270 wby, or wsm focused on 150 to 170 weight bullets. Main targets will be Texas whitetail and lots of hogs as far as I can see 'em.
Anybody have any pros or cons, better ideas or just plain don't do its?
I do my own smithing, money isn't an issue(but I am kinda tight), and been reloading for 30+years with plenty of wildcats in the mix. What do y'all think?

Sounds like a great project. 270WSM with a 1/8 twist. My Rock Creek barrel is a absolute hammer. Speaking of hammers it would also be great with Hammer Hunters. Throat it long for the Berger 170s and Hammers. You will need a mag length of 3.125 to take full advantage of all this custom rig has to offer.

Building a .270 sounds like a grate chose to me. I'd probable go with a .270 Win. , but the wsm and weatherby would be good choses. Look forward to hearing what you go with and how it turns out.

I like the .270 WSM idea, too. Power to push those heavier bullets at good speeds but recoil should be reasonable. Then there is the ability to buy factory brass and 'standard' dies, which saves some money and hassles. I guess it depends on how fast you want the bullets to go. But you know the drill - no free lunches; more speed = more recoil. Gotta find your 'happy place' in all that.

.270 RPM...or just a standard .270 Wby or a 27 Nosler.

Let me elaborate on my ideas on recoil. I will tolerate a little more recoil for extra performance. But, I don't want to get into stupid amounts of burnt powder or larger than needed bullet wights( Ex:26,28,30 Nosler, 300 win) to be an efficient killer of pigs. Often too I take folks hunting that aren't experienced shooters and let them take game at extended distances, so cannons with big muzzle brakes aren't conducive to business.

So....270 WSM is your huckleberry! (And I'm with you on the muzzlebrakes; they are obnoxious and I dislike them.)

I really like the .270 WSM, but if you're not afraid of wildcats I'd have a talk with Rich about a Sherman...

I like the 270 WSM, I've seen it in action and it works great. But if you are in to wildcats then hands down th 270 SS, no question about it

I have played with two different .270 Shermans that we put together. H-1000 under a 170 EOL is going 2950 fps out of a 24.5" barrel. I prefer the .270 Sherman (as opposed to ss) because brass is cheaper and easier to find, and was super easy to make. Run a .270 case through a 30-06 die (just to expand to 30 cal, other 30 cal dies would work too) then run it up into a non-bushing 7mm rem mag die without the expander ball. Dump powder, seat bullets and go play to form brass. This creates a false shoulder, and when ran all the way up in the die, a standard 7mm rem mag die happens to place the shoulder perfectly for a crush fit, and because it is a non-bushing die that relies on the expander ball to size the neck, it sizes it down to .275 or so, just about right for seating .277 bullets. After the brass is formed you will need the .270 Sherman dies of course, but you can get started without them if you wanted if you have a few standard cartridge dies. Left is loaded round with false shoulder ready to form, and right is formed case. Made with a 30-06 sizer, 7mm rem mag sizer w/out expander, and standard .270 win seater die. Fun cartridge to play with!! And also, essentially no trimming thanks to the 40° shoulder.

Why not just take a .280 Ack and neck it one pass to .270? Seems like much less work and custom dies wouldn't be needed.

How about a 6.8 Shaggy?

Didn't think a .270 winchester Ackley was a standard chambering? However I suppose you could just get a cheaper .280 Ackley bushing die set and get bushings for .270, for a full set that puts you around $200, not terribly far ahead of the custom Sherman Whidden dies, but you could also get just the bushing sizer and bushing for around $85-$90 (with bushing), and use a standard seater I suppose, and save some. Otherwise, the .270 Winchester Ackley dies are about the same as any other set of custom dies, which save you around $100 over the Whidden Sherman dies.

Either one would be a decent option though.

Feenix, are you insinuating I should design my own wildcat and name it after myself!?! I don't really need your help convincing myself to do something expensive and illogical!
