what cartridge should I have built with a standard action model 70.

[Ballertrawler II]

Well the 27 Nosler idea is out as i did not do enough research and my donor action wont work. it is a Model 70 chambered in 270 Win currently

So that opens it up... With what I already have I was thinking of the following but am open to suggestions as well I want something over 3200 fps or faster

from 6mm to 7mm.

Some of things I am thinking of are

6mm -06AI
6mm-280AI
280 AI

I have a 270 WSM and 300 WSM, which is why i am looking for 6mm

[elkhunter11]

25-06, or 6.5-06 would be worth considering.

[1dayillgetaram]

6.5 or 338 rpm

[brewster29]

25-06 ai.

[bat119]

280 ai

[Engels]

im with elk on this one. 6.5-06 could be a cartridge that could check the boxes for you.

[rugerfan]

240 Weatherby would be an option as well, would give you something with factory cases available.

I've always felt that a 6.5-06 would be an excellent, fairly low recoiling round.

30 Gibbs
35 Whelan Improved.
338/06 AI

I have owned dozens of 6.5 rifles using the " standard "
( 308 sized) case head , most were fantastic.
The 6.5/06 was one of the best and would do another in a heart beat.

Going up to 7mm, I really like the 280 Remington and the 280AI

Good choices

Why change anything. What are you expecting to gain?

Probably something different, not necessarily better

It will hold 5 down, feed like it should and with 117gr hammers will get 3200fps.

You could throw a 26” barrel on it, a Bansner Miller stock, and Sunny hill bottom metal.

[rugerfan]

If you’re dead set on that 3200 as a minimum velocity it’s going to limit your choices. A couple of the 6.5s would in the right barrel length, or the 280 AI but you will need to stick to lighter bullets.

[cowmanbob]

Keep the 270 win and use 110 grain bullets. With MRP powder I’ve gotten 3400 FPS.

[obsessed1]

I'd stick to the 270 myself. Given your cartridge stable though I'd go 338-06 or 35 Whelen but you won't meet your velocity goal with either.. 6.5-06 is the only " change" that would make sense and meet your velocity requirements but candidly it won't do anything better than your two chamberings you already have.

[fps plus]

6-284
6mm Ackley
240 Wby mag

I have used the 3 above and currently use
The 240 Wby.
