New 7mm rm load

[7mmVertigo]

Hey every one does anyone have any experience with the matrix 7mm 190 gr vld? Made by matrix ballistics and they claim that it has a bc of .8071 with potential of velocities well int 3000fps. Any input would be appreciated before I begin this new load for my custom 7 mag.


Here is the link for their page:

Okay since i cant get any replies on this matter maybe i posted in the wrong room but can anyone give opinions on powder types and loads for this bullet? i just bought some matrix 190's and im looking for some reloading advice on where to start. id like these to chrono as close to 3100fps as possible. my barrel is 26" so it shouldnt be too difficult to achieve. Ive read that the berger 180's have good success with 64gr of slow burning IMR4831. any insight would be appreciated. thanks

safe shooting

Well, I don't have any experiance with the Matrix bullets... But I am currently working with the Berger 180gr Hybrid in my 7mm Rem Mag. I'm using Retumbo, found a node in the 68.3gr area. With a 26" barrel I'm getting and average of 2889fps. Tested all the way up to 69.5gr which got me 2930 and no excessive pressure... Keep in mind, I'm running this in a factory Remington Sendero.

Quick history of my test, for your info.
67.5gr=2835
67.9gr=2865
68.3gr=2889
68.7gr=2894
69.1gr=2911
69.5gr=2930
69.3gr=MAX
