Re: Load work for Ruger 270 Win, for Elk

Hey WinMag, appreciate you chiming in. You do have a good point.

In short, right now I'm working up loads for the Matrix RBT (a bonded bullet) at 150 gn and the 165 gn Matrix hunting VLD bullet.

our goal is to be able to take an Elk with one of these bullets out to 500 yards but we will attempt to get as close as possible of course. We would only shoot to 500 yards in a rare instance where we could get no closer.

But Big Green's confidence in the 165 VLD's however has spilled over on me some so I'll see if I can make them work on paper first. My first attempt with the 165 VLD today with the 270 winny didn't go real well. 60gn of Magpro just netted me an average of 2580 FPS. Two rounds were within an 1' of each other but the 3rd round was a flyer at about 3" from the other 2 rounds.
After loading these first few rounds and testing I'm beginning to think maybe top end on these 165's would be 2700FPS at best with this rifle and that's pushing it beyond max published loads. I'm not giving up yet.

I did get a decent group of 1" and OK velocity (2660 average) out of my 270 WSM with 66 gn of Magpro. If I can bump that up to about 2800+- FPS with good accuracy I think I'll go with the 165.

We've been waiting on the completion of the Colorado draw to see what area we get. We had no preference points but based on previous years, odds appear to be in our favor of getting our first choice for the Elk 1st rifle season. But we did put in for 3 other GMU's should we not get our first choice. June 4th is when they say the results will be available on-line. Seems like it's been a long wait but only a couple weeks to go.

If your rifle don't like the Matrix there are a lot of good bullet that will do you good in that range, I try not to get to excited about the Matrix bullets but man when you see bull after bull nose dive and internal organ are shredded it's hard to not get jacked

Re: Load work for Ruger 270 Win, for Elk

Maybe some hope after all for my 270 Win and the 165 gn Matrix. I loaded one bullet this evening but before doing so I went back and looked at the load that shot well with the 150gn matrix and copied some of the elements of that load. I used a WLRM primer, Norma brass trimmed to 2.535
61gn of Magpro with the bullet set about .082 off the lands. Put a brand new battery in the Master Beta Shooting Chrony and got a reading of 2828 FPS!!
. I couldn't believe it. In my last post it was looking like I wouldn't get above 2700 FPS. I do not recommend anyone using this load however without starting from a min load and gradually working up as this I'm sure is a max or greater load for most 270's. This 270 though I don't guess read the loading manuals.

Now I need to load a few of this formula and see if they really fly this fast or if it was a one shot fluke and see if they group at the same time. Of course this load may shoot like crap in my partner's gun but at least it shows it may be do-able in a sporter rifle. I always like puting together workable hunting loads for my rifles anyway and hopefully this will be one of those.

For what it's worth I'm not against using other bullets too. I really like the Barnes TTSX's. It's a really tough bullet and expands well and penetrates extreamly well. The 150 gn version gets pretty long as it's copper and a 9/1 twist is recomended. I suppose it's not any longer than this 165 grainer though. Anyway, I got some loading to do.

Re: Load work for Ruger 270 Win, for Elk

Thanks to all who contributed their thoughts here.

I loaded up 6 more bullets yesterday and went to the range today and had better success with these bullets than I even expected at this point in time.

Three of the Matrix 165gn hunting VLD bullets were shot from the 270 winchester and they shot great! However the first bullet hit my difuser for the chrony and who knows where it went but the other 2 bullets were touching. The load was the same one from my last post and indeed they averaged over 2800 FPS (2810 FPS). Not super velocity but I checked a Ballistic Calculater and it will have quite a bit more energy and Velocity than a average 140 gr bullet with a MV of 3000 FPS at 4 and 5 hundred yards.

That load was from once or more fired Norma cases trimmed to 2.536 and neck sized only with a bump neck bushing die with 61 Gn of Magpro powder and the bullet was set at .085 from the lands. WLRM primers were used. I tried in some prevouse loads Federal Gold medal Match Magnum primers but they didn't seem to work well with the Magpro powder. I think the Magpro needs the hottest primer you can find. Keep in mind this is an unpublished load and most likely too hot for some rifles so start around 58 grains and slowly work up.

The other 3 rounds were for the 270 WSM and they shot OK at 1 1/8" 3 round group at an average of 2915 FPS but that was with new full length sized norma brass trimmed to 2.092. With a little tweaking I am sure I can trim that group down somewhat.

I'm good with the velocity for both these rifles with the Magpro powder but I'll probably expierment with some other powders too. I don't know how the Magpro will do in Cold weather so I'll expeirment with some slower burning of the Extreme powders like H1000 etc to see if I can come close to the same numbers with these sporter rifles.

Re: Load work for Ruger 270 Win, for Elk

So you got the 165's to stabilize in whatever North Carolina has for elevation above sea level. I was curious if it could be done at low elevation, & at spring time temperature. Very Cool! Are both your rigs 10 twist barrels, or are they spun tighter?
Congrats, & sorry to here about your chrono.
Keep us updated.

Winmag,

Yep, got them to stabilize at maybe 500 ft elevation or somewhere near that.
Yes, both rigs are 10 twist barrels. The chrony wasn't really hurt, just nicked the bottom of one of the defussers, didn't even break it, so it's all good. I have some etras anyway that are better made than these newer one's are.
I just took the other one off after that and it seemed to display the velocities fine without them on.

Re: Load work for Ruger 270 Win, for Elk

I just wanted to do a little update here.

My friend and I finally got together at the range today and shot some 270 Winchester, 165 gr Matrix Hunting VLD bullets in his Ruger with 22" barrel that I had reloaded for him. I reloaded 9 bullets in 3 shot groups with 56.8 gn of IMR 7828, 61 Gr of RL-25 (slightly compressed) and 60.5 gn of Magpro.

The Magpro had the best group of the 3 by far at 1/2" and averaged 2680 FPS. The question was asked prevously by someone if the big 165 gn 270 matrix VLD bullet would stabilize near sea level with a over the counter, ten twist sporting rifle and I gotta say now the answer is a definite "YES".

The RL-25 was was slightly compressed and velocity averaged around 2700 fps but with being compressed already not much hope of getting more velocity.

With both my 270 Winchester and his Ruger 270, so far the most promising loads have been with the Magpro. I see no pressure signs with this load so I believe it can be bumped up another .5 grains in his rifle to 61 gn of Magpro.

I have alreaday shot my 270 with 61.5 gn and it did show some signs of mild pressure so that may be the max for my rifle but velocity was over 2800 FPS and accuracy still good.

Again, I don't recommend anyone use these loads without starting much and working up.

I have my friends Ruger rifle now and I'll do a little more testing this coming week with additional loads especially with the magpro and report my results here.

Terry
