Home Forums Hunting & Shooting Ask The Gunwriters Initial range test Reloder 26 with 150's in .270 Winchester

It has surprised me in quite a few cartridges so far. If you can get enough in there I have no doubt it'll make speed..

Funny how that concept is lost on so many people...

Yep, but a lot of hunters (even handloaders) are obsessed with muzzle velocity, just as if it was still 1900 and smokeless powder was the new kid on the block. That was reasonably valid when almost all hunting rifles had iron sights and 200 yards (often guessed as 300-400) was considered a pretty long shot, but things have changed a little since then. :-)

Those 160's are great bullets and over 3K is nice to get.

But, I would bet the longer shank of the bullet is creating higher pressures for you to get that kind of speed.

I'm not seeing any indications but I intend to back off a bit for safety.

Here,s a few recent loads of mine with RL26,RL23 And Norma
MRP in 270 Win.

Guntruck50,
You're getting great speeds, how was the accuracy?

For sure. Those look like excellent loads across the board.

I tried 61 to 63 grains of RL26 behind Nosler 180AB, 180PT and 180BT. The 63 grain load gave me 2940 fps so the powder is fast in my 24" barrel but groups were bad. Rifle shoots these same bullets well under MOA with H4350.

I,m still trying to figure that out. I used Norma
MRP to get my Elk, This year, 59.2gr with 150gr partitions.
About 2981 Average. I,m going to use 140gr Accubonds next
year. the 130gr TTSX best load is with RL17 54.5gr at
3208fps, I,m going to back off to 54.0gr. The RL23 load
for 140gr Accubonds was the most accurate. Have several
other powders that shoot good with the 140gr Accubonds.
For deer next year I,ll probably us the RL23,if not
that It will be MRP. I,m still working on the RL26.

R26 in the .300 RUM is also pretty phenomenal. Shooting a MRC X2, with 180 Accubonds, velocities are very high, and it shoots bugholes. The 190gr Accubond Long Range needs some more tuning, but still it did 1", and made high velocities.

Where'd you find data for the .300 RUM?

I did some testing back in Dec 2014

Love the 160s, even at 2800 or so. Of three deer taken so far, two good bucks and a doe, two were literal DRTs and the other went about 50 yards. 150s are no doubt just as good, but the 160s have that retro-badass look to them, like some fancy Euro-ammo.

I started with Reloader 22 max loads, which in this rifle is 87gr for 180gr Accubonds.

Yup they have the look, that sinister semi-spitzer thing going on. I have a few boxes of the NP 160, 2 pounds of RL26 & some new 270 Winchester brass....

Looks like I found my winter project.

Resurrecting this year old thread because I finally have something to contribute.

Went to the range today and dragged out the chronograph.

Chronograph set 12' from muzzle. Kimber 84L 24" barrel

All loads were COAL 3.300" which is about .030" off the lands.

1 round to verify previous testing, this is my previous load for 150 grain Partitions.
Win 1x brass WLRP 56.5 grains H4831 150gr Partition 2805fps
The Hodgdon max load for H4831 and a HDY SP is 55.7 grains , so I am over that by almost a full grain.

Nos 0x brass WLRP 59 grains IMR 7977 150gr Partition 2805fps
2805fps

Nos 0x brass WLRP 60 grains IMR 7977 150gr Partition 2885fps
2879fps

Nos 0x brass WLRP 61 grains IMR 7977 150gr Partition 2953fps
2938fps
The Hodgdon max load for IMR7977 with a 150gr HDY SP is 60.8 grains, I rounded up to 61 grains.

Rem 1x brass Fed 210 60 grains RL26 150gr Partition 3081fps
3090fps
Alliant's website shows a max of 60.8 grains of RE26 with a 150 Partition. I had some old Remington brass already sized and primed with Fed 210 primers so I just went with it. I had 3 rounds loaded, but after seeing the first 2 readings I stopped. Thought I may have inadvertently overdosed the powder. Just pulled the bullet on the unfired round and weighed the powder, 60 grains exactly. Looks like RE26 is indeed the magic powder for 150s in the 270. It was a little breezy to do accuracy testing, but all 9 rounds shot into a little over 2" at 100 yards.

Looks like the modern 270 no longer needs 130 grain bullets or 4831 powder.

Alliant shows about 3020fps with a 24' bbl and the 150gr NPt. Even though you haven't exceeded the max listed powder charge, I'd be a bit leery of 3080+ fps............

That's why a chrono is our best pressure testing device.........

And yes, it seems RL26 has taken one of the original "magnum" cartridges a big step further.

I am getting 3040 fps. with a 22" barrel and it is my hunting load/ 150 gr NP
