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.

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. -- richard

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.

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**

here's a summary from my initial ladder test... others here have done more extensive testing including hunting

Lucas Beitner did an excellent job on this article >>> 270 Win For Long Range Shooting Berger will soon come out with a 170gr and will be available at https://store.extremeouterlimitstv.com/ >>> see post #20 of http://www.longrangehunting.com/for...reme-heavy-hybrid-170-grain-95746/index3.html

looks like this will be a compromise consisting of the following factors. 1. Must fit in the mag 2. Must have a jump to the lands (hunting use) 3. Using Winchester Brass 4. H4831 Powder...or H1000 5. CCI BR-2 Primers 6. going to try for 2800-2900 ft/s

been looking at some data from various sources... While I know that the relationship between powder charge and energy is not quite linear, it looks like I would need 59 grain of 4831SC or H1000 to get 2850FPS from a 165 grain bullet. can someone with a Quickload verify this for me?? Barrel length is 27 inches Mostly currious where pressures are at.

hmmm 59 grains is WAY hot according to information here Reloader's Nest Forum - .270 Win 160g Partition load will start with 54 grains and work up

You look like you should come up on a load, we start the wins at 52gr of H4831sc or 7828 with BR2's. If I remember right we load around 56 gr for 2830fps which is a little of the top but plenty good for what we do and it's ridiculous small groups. Seated deep to feed form the mag as also.
