160 Gr bullet in a .270 Win

[Treeman]

So here I go again. I managed to get a box of .270 Nosler Partitions in 160 gr, a bit pointless because there are only 50 in the box. The good news however is that a local bullet maker is interested in making the bullet for me cup and core style.
I honestly believe this 160 gr in .277 will have penetration of note and that a cup and core bullet will be usable to better wound channel results than any 150 gr mono or premium bullet.
Has anyone on site ever used a 160 gr bullet in their .270 Win ?

In a 1 in 10 twist rifle Gyro Stability calculates at 1,67 at your altitudes. Should stabilise well and give hunting accuracy.

Yes I have not read a post world wide of stability issues.

Can you give comparable weight for another similar calibre?

It sounds like 200gr in a 30-06?

What speed would you achieve with it?

Using S365 with the 160Partition a speed of 2800fps is safely possible.

Max speed is not a safe accurate load. Depends on barrel length as well. I have used a 24 inch.

100fps might relate to 1 inch at 300m.

I must really get down to reloading these 160 gr I have, was hoping to get some more to have a useable amount.
My quick Load seems to have died, must find out whats wrong with it other than being about 12 years old.

I've shot 160gr Speer Cup n Core in 7x64. 0.2mm wider in diameter than a 270. They penetrated Ok, and did a lot of internal damage as I had a lot of cup core separation with these.

*******************************
Do not think the separation was due to it being 160 Gr ??
Velocity ?

Speer 160 BTSP. 2850fps would be the speed for a 24 inch barrel.
