Re: Load work for Ruger 270 Win, for Elk

Most of my hunting is between 4-6 thousand feet. The area i pulled my elk tag for is more like 3-5 thousand feet. I figuring on setting the turret at 4K and just do a lot of shooting this summer. Cant wait for wolf season either! Thanks a bunch for everyones help! Larry

Here are the results from my test using a ProChrono at about 12 ft from the muzzle:

1. 55 gn RL-19= 2656, 2. 59gn H1000=2677, 3. 51.6 Gn IMR 4350= 2640,

4. 53 Gn IMR-4831=2640, 5. 61.5 gn Magpro=2824,

6. 56.5 gn IMR 7828= 2688

WLR primers used for all except WLRM used with 7828 and Magpro. All cases were once fired Norma cases neck sized with Forster bushing die.
The rifle used for test was Remington 700 270 winchester, with 24" barrel.

All the published data I have say's these loads should fly about 100 plus FPS faster than they do? I have checked the chrony agains a new Shooting Chrony and get pretty much the same results.

Any thoughts anyone as to why the velocity discrepancy??
I just wanted to note here for posterity's sake the velocities above were with a 150 gn 277 bullet, I believe with the Matrix 277 RBT, not the 165 Matrix VLD.

Re: Load work for Ruger 270 Win, for Elk

Hi,

In between working, vacationing etc I'm still working up loads for my friend's Ruger 270 Winchester based on the 165 gn Matrix VLD hunting bullet. At one point I thought we might be stuck at 2700 Fps velocity but I now have several loads at 2800 FPS or close and not seeing signs of severe pressure. Other than with the MagPro powder however I can't yet vouch for accuracy I am at near max on velocity with these loads so I'll soon be checking accuracy. These are my results thus far. Keep in mind these loads are most likely too hot for some rifles so back off a couple grains and work up. These results are from a 22" barrel.

Cases are Norma, primers are WLRM

1,Winchester 780: 60gn = 2820 fps

2. IMR 4831: 55gn= 2752

3. RL-25: 62gn= 2815 - compressed

4. Ramshot Magnum: 62gn= 2825

5. Magpro: 61.4gn= 2770

I used 2 chrony's to obtain the FPS with a Prochrony and a shooting chrony (beta master) directly behind it. Generally the FPS were very close to each other.

At 2800 FPS one ballistic calculator showed the following results using a G7 BC of .65 for the 165 gn Matrix VLD.

At 300 yds a Drop of 11", velocity of 2624 and energy at 2525
At 500 yrds a drop of 42", a velocity of 2510 and energy of 2310

Re: Load work for Ruger 270 Win, for Elk

Terry I'm following this thread pretty close, I've been using Partitions for years in my 270 but with what I'm hearing about Matrix bullets and that their less expensive than partitions, my interest is peaked. Keep up the good work

currently I'm working up a load for the 7mag with 168gr Matrix VLD's, I have a 1 in 10 twist so with how close 168's perform to to 180's /190's I'm good with it, besides the initial testing shot round Robbin style all 5 powder charges shot 1moa or better and POI was within 1/4" for all charges

Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.

Re: Load work for Ruger 270 Win, for Elk

Hi,

Just thought I would refresh this post. We are still loading and shooting these 165 gn Matrix VLD bullets in my friends Ruger 270 Win and my Winchester 270 WSM and still likeing them very much. I have pretty much settled on the Win 780 powder and GM215M primers. We are using 59.9 Grains of powder in the 270 Win for the lightly, partially neck sized rounds and 59.7 gn in the Flull length sized rounds as they are crimped a bit tighter thus more pressure/velocity. They are cronographed at just above 2850 FPS.
I gotta reinterate however this is a max load so work up slowly.

We are getting out to shoot at least once a week and have begun to shoot at 200 yrds and hope to do some shooting out to at least 300 yrds soon.
My friend with the Ruger impressed the heak out of me at at our first time shooting at 200 yrds with 3 of 4 rounds at 200 with a sub .5" group. This with the full length sized loads I made up for us to practice with. They are .095 from the lands in the Ruger.

We have shot much of the neck sized brass multiple times so I am Full lengh sizing the Norma brass right now as they were starting to get hard to load in the chamber. The Norma brass seems to be holding up well. I would like to sometime Test the full potential of these rounds at long range sometime but for now we'll limit our hunting to ranges have shot at and feel confident with but getting there.

Good hunting..

It is also one heck of a jump to the lands........rich
