264 Win Mag 160 Matrix Data

[ramrod79]

Hey guys I did some searching ,and not sure I was able to acquire what I was after but I am thinking about doing up a 264 win mag but before I start I would like to know if anyone is shooting the 160 Matrix as this is what I want to shoot out of this rig I would also appreciate barrel twist recommendations, I figured a 1-8 would work just fine but though I would ask .
Any info anyone has for me would be greatly appreciated.

Matrix lists 1 in 8 on their website for this bullet.

+1! Rich (ELKAHOLIC) used them before but if IIRC, he found out that the 150s are performing better. Could not remember if it has something to do with the jacket? I'm sure he'll chime in as soon.

Good luck!

Guys were annealing the 160. The jacket is so long that it folds over itself from my understanding. It is a very accurate bullet in my friends 6.5 Sherman. My Sherman did not like it as much as the 150 Matrix or the 140 Berger. I would try the 160's out. You got the Horsepower with the 264 WM

Thanks guys even the 150 GR bullet has to have some pretty impressive ballistics out of a 264 Mag I would just like to have that bigger bullet than the 140 for big animals I do a lot of Elk hunting.
What is the BC on the 150 as I could not find it on web page .

Here is a 150 recovered from a deer with an impact velocity of about 2200fps

I believe the jacket on the 160's is a bit thick for hunting at distance.

Try a search on here. Litz did a full BC test on the 160 and 150 Matrix. The 150 I believe is. G1 BC of .640 above 3000 fps. With a BC of .604 averaging from 3000 fps to 1500 fps.

Beat me to it LOL. Must of been typing at the same time.

Thank you that is some great info a 150 with that BC being pushed at over 3000 really looks promising for a good ELK round . I plan on trying something different by using a Savage 116 action and getting a 26" pre fit barrel from Benchmark with a break I am not doing anything Fancy to it just a cheap build to play with .

I would imagine you'd get over 3000 fps with that set-up as I'm getting about 2920 from a 26 inch 6.5-06.

I've used that bc number out to just about 1400 I believe and it was spot on using a kestre with Horus.

 

[ramrod79]

Not to get carried away I used 3100 with the 150 BC you gave me ,and wow this just may be fun . What do you guys think for powder ?

 

[BEEMAN]

I think you will get 3100 out of a 264 WM. Guys are around that with the 6.5 Sherman and the 160 Matrix. I get 3329 fps with a 140 Berger out of my 6.5 Sherman with N570. I would try N570 or R33. H1000 or Retumbo may also work. Can't remember off hand how fast I was pushing the 150 Matrix. I believe I was around 3200 + or -. With us being in Canada R33 is basically a no go. N570 is available if you look around.

160's shoot good in my 8.5-twist, it's 264wm..

I'm waiting on a new scope at the moment to re-verify everything, but my max-MAX was originally 70.5 Retumbo if I recall right and was well over 3100, nipping at 3200 actually. I got away with "that" largely in-part with the chamber-job itself. The throat is a longer throat than typical in mine, specifically cut for the 160.

...anyway, I turned down from that max to 67.7 (again if I recall correct) and it chrony'd out right at 3045. Also Retumbo. Been trying to find N570 a long time without any luck, so Retumbo is where I've stayed. Same comment as BEEMAN regarding R33, no go/no-way/no how for us on this side of the line.

Thanks this is good info 3100 with that big high be bullet will really hammer way out there.
