What is the the most flat shooting cartridge yall can think of?

[1mechanic]

264 Win mag with 80 hammer hht at about 4100 fps.

Edit: now it might be to much of a powder burner for your goals.

These are book velocity maximums from the Barnes web page entered into the Hornady calculator at my elevation, the .270 win holds its own pretty well.

In my opinion the 270win and especially the AI version or sherman version are one of the most overlooked family of cartridges.

It's not the power as much as it's finding good brass.

Lot of bang for .473 bolt face.
Time and technology have found better but they still perform.

Have heard PPU is good trying to find some, most people on here seem to like it. Rhett Crider had a wildcat on a 264 or a modification to the 264 I think he was using PPU brass I pm him to ask how many loads he got on the brass, never heard back thought oh well. Then saw months ago he died felt bad for his passing and then thought about how much knowledge he had that I wish I knew. RIP Rhett.

The flattest shooting cartridge I own is my 270 Weatherby Mag, shooting a 130 Grn Ballistic Tip at 3300fps, or the 150 Grn ABLR at 3000 fps. if the range is from 100 to 500 yards The flattest shooting cartridges I can think of at the moment ,are 7mm PRC .or the 6.5 X 300 Weatherby.

Dad wants a fast twist 270win AI and has for years. His pre 64" model 70 super deluxe Denali King ranch grade or whatever it is looks like when you first pour cream in coffee and is just too pretty to take apart and he will not buy another rifle of the same "caliber" unless it's rimfire then he's got a 22lr in every corner of the house lol.

I'd have him one built but he's shooting deer from a bow stand with a 30-30 these days lmao........says he "can't see real far"..... he just likes to watch em up close and shoot a spike for meat once a year.

28 nosler at 3200 fps with a 195 Berger

The OP is talking about MPBR which has nothing to do with ELR. Hammers maximize MPBR potential for most cartridges.

Yep

.223 WSSM....!

I'm getting 3700 out of a 90 gr Absolute hammer in my 25-06. +2.8 @100 +4.1 @ 200 and -4.2 @ 400 at 3500 ft elevation.

Should have mentioned the accuracy holds even when shifting powder charge weights by as much as 2 grains.

So as the .270 Gibbs. When it is time to re-barrel my .270 AI, I might do a .270 Gibbs or another .27 cal wildcat. I have a .30 Gibbs and propels the 190 Berger VLDs at 2806 FPS with powders I already have opened (not necessarily ideal) with more room to spare.

25-06. or for inside work 22 Hornet

Factory IMO I would give it to the 50 grain .22-250 Hornady at 4000 fps. Hardly any adjustment from 200 - 250 - 300 yards. Goes transonic around 730 yards.
