Best .277 cal cartridge?

[nathank]

This question has probably already been beat up, but I will ask it again. I do mostly deer hunting and as far as I'm concerned the 277 cal is the best calibre for deer as I have seen many many deer shot with many calibres and have never seen one do as good a job as my 270 win, I've seen deer go farther from a double lung shot out of a 338 wm than most I've shot with my good old 270 win. I know there's not a lot of high bc 277 bullets out there but I don't care, maybe someday berger will have out a nice 277 bullet. Anyway what are some of the 277 shells out there and what are your favorites?

Are you talking about factory chambered 270's and or wildcats???

Probably 2 of the hotter factory 270's would be the 270WSM and 270Weatherby.

If you're talking about everything that has been necked to a .277 the list would be pretty long.

I think Kirby Allen's 270AM is a pretty good choice and in about a year or less I will know first hand.

The 270 Weatherby magnum is the best factory 270 by far. Bunch of wildcats. The 270 wby is just an awesome hunting rifle. The 270 WSM is next. It falls exactly half way between the wby and the 270 win in velocity.

Interesting thread, I am also a 270(.277cal) lover. Thanks for posting. Hopefully we will get some great info out of it.

The 6.8 SPC uses a 277 bullet. One of the better choices if you want to use an AR-15. Good for small deer at moderate range. What weight deer do you have where you hunt? What range do you typically shoot at?

Could you provide some examples for the 270WBY, I'm sure from reading some of your other post you have wrung it out to see what it will do. I'm curious as from the best data I can find I'm running my 270WSM right with it.
I had a friend in high school that had a 270WBY and boy it was awsome, always wanted one.

I have shot the 270 wby extensively for about 35 years. My longest shot with it was an elk back in the 70's at over 1100 yards. I like 7828, magpro, retumbo with heavy bullets, RE-25, all do very well with it. Basically top velocity with extreme accuracy are as follows. 130 grain bullets-3500-3550 fps, 140 grain bullets 3400-3450 fps, 150 grain bullets 3300-3350 fps. All three of mine have 1-10 twists.

I have chronographed quite a few 270 WSM's, mostly when I had my shop and range, but do not own one. All that I measured hit about exactly half way between the win and wby.
