270 winchester reloading

I have ben reloading for a while, and am familiar wth the common hunting bullets for the 270 Win (130 and 140 grain stuff)

However, I am interested in loadin up some 165 and possibly some 175 grain Matrix Bullets.

I have the nosler book with info on their 160 grain Partition, and could use that as a starting point. However, I am looking for some actual tested information frome someone who had used loads like this.

I have three powders in mind, H4831SC, H1000, and Retumbo.

The barrel is a 27", 9 twist.

At what point do I loose efficiency? I would like to squeak as much velocity as possible with these longer VLD bullets.

Also, does anyone other than Matrix make these heavier VLD bullets?? I dont mind giving the Canadians money, but if a US company made some, I would rather give them my business.

Re: 270 winchester reloading

With the hits this thread has recieved, I guess I should be more clear as to what I am tryong to achieve.

The end goal is accuracy, with as much velocity as the weapon can achieve with the 165grain matrix VLD.

I think I may be able to get 2850FPS, but if it is not accurate, then I would have to back down the load till it works...

so, does anyone have a starting point that would be recomended?? Not looking for a max load, but looking for an accurate load.

also, does anyone know if the Matrix VLD is jump sensitive like the Berger VLD??

I don't have my data handy right now.

they are good bullets
about the only game in town for high bc 270
easy to deal with

Type "165 matrix 270 win" in the google search box in the top left corner of this web page.

Re: 270 winchester reloading

you could always try e-mailing them directly. I've done this for Berger bullets and they are more then happy to provide data. I assume you are knowledgeable about what your seating dimension is (that is OAL to ogive) in your gun, this , combined with using a chronograph helps stear you in the right direction.
I would also cross reference to other reloading data, such as Sierra or Nosler..
You may get better performance at longer distances (over 300 yds) then what you might find if testing at 100/200 yds due to bullet stabalization.
I have not used these bullets.

.277 Matrix Bullets... wow! - 24hourcampfire


You may glean a little useful info from these two links. You have to really wade through the post on the 24HCF but there is some stuff there.

If you haven't searched this site yet for Matrix & 277 you may want to give that try as well.


Let us know how it works out.

**I posted wrong link on top at first. Have right one there now**

Re: 270 winchester reloading

here's a summary from my initial ladder test...

others here have done more extensive testing including hunting

Marshal,

I finally got around to shooting my first quick ladder with the 165's today.

The first 4x were 50.5gr h4831sc with CCI BR2's. One bore sighter, adjusted scope, then 3 in the same hole ~.25".

The rest were pairs from 51-54.5gr in half gr steps. All of the other pairs were under an inch.

53,53.5,54gr seemed to be a node with all 6 shots under .5" and single digit ES.

Velocity ran from 2435@50.5g to 2696@54.5g. And, I never really got any pressure signs. So, I might try for a little more velocity.

...nothing conclusive, but well worth going back to shoot some groups.

Also, this batch was .010" jammed and won't fit my magazine. I just wanted to look for an accuracy load first and then work on seating depth and/or magazine issues.

thanks
