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

My results much the same, looks to be a perfect powder for the 270 Win pushing a 150 grainer.

I started up with the 150 LRAB & RL 26 in my 25" Benchmark re-barreled Ruger M-77

Impressive to say the least, worked up to a safe 3150+ fps & sub 1 MOA for 3 shots. Staying within Allients loading data.

Reference this thread if interested.

Funny how every once in a while a new powder hits the sweet spot for a particular cartridge. The advancements are incremental these days.

That has been my experiance so far with a pair of 270's and 150 gr NBT's and NPt's.

It seems to burn a bit cleaner than H4831--especially in those fouling mutha's of a 243 ......

What's impressive, and helpful to me is that the Alliant manual has data for a number of different bullets of the same weight with the same powder. With RL26 they have data for four 150gr .270 bullets and three 100gr .243. With component supplies (and prices) being what they are nowadays, that's a big deal.

Yep. for a while, Alliant was only showing loads with Speer bullets, Speer of course being another division of their parent company. Good to see them using other bullets

Can't find a teaspoon of 26 anywhere in a 250 mile radius of home base. I do have some 25, which I know is similar to 26, just not as temperature sensitive. Is it close enough to use the 26 data with no problems? Close enough to reasonably expect the same results?

There's no RL25 data for the standard .270WCF listed in the latest manual at all. There is some for RL23, but at a quick glance it looks to be several grains down. The manual is a free PDF file. Best download it and see for yourself.

Well, my first effort with the Ruger #1-A on the bags sure looks promising with the one and only bottle of RL26 I've ever seen. I had some old Hornady 150s around, not even sure if they're Interlocks or not, but they sure bucked well....much more than 140 BTSPs with H4831, so I would assume they're moving along. And they print higher as well ..... and in tiny little clusters predominantly, something I never knew whether this rifle actually had in it. (It's kind of a storied little rifle, but fortunately the bore was not scarred in the process....note, I did not say barrel ) Anyway, thanks, John, for the head's-up on the powder/bullet combo. I may load a few with 140s just to satisfy my curiosity when I refill the empties.

I'm looking forward to trying 26... no one I could find has it around here yet.

Barnes had it in Manual #3. Listed 65 gr max of RL25 with 130 gr XLC for 3299. I got 3200 from a 22" M70 Classic barrel.

I also worked up loads with Partitions in 130-150 hr bullets but cannot remember details except the powder worked very well in the 270.

I would not hesitate to use it in the 270 at all.

Dang, that's smokin'!

Given that the longest shot I've taken on a deer in the last 20 years was maybe 125 yards, my interest in pushing for more speed might be a little silly, but a boy's got to get his fun someplace.

I tried some 150 partitions and RL26 today. Used WW brass, CCI 200 primers, 60.5 gr of RL26. Tried in 3 different rifles. Velocity ran from just over 3000 fps to 3060 fps in the different rifles. Two rifles grouped well. the other did not.
I'll be loading another box of these soon.

With all the new powders on the market, I say you have to consider the long term availability. Just about the time you develop a load, some new press for gun control hits the news and starts the hoarding mentality up all over again.

This is true.

RL_26 had become my new everyday powder for the open country streamlined 150. Going to definitely have to replace the old rock hard red recoil pad on the M77.

Like RL_17 with 130 TTSX for speed goats

And IMR 4831 with Nosler 160 Partition for timber.

But then I'm OCD & picky too boot!

Ditto on the 160s, but I push them with a couple of jugs of Supreme 780 I was lucky enough to find before they pulled the plug on it. Both the doe I shot and the big 10-point my son shot last year just FOD (Fell Over Dead, DRT is passé and bang-flop sounds too much like a description of old-man sex). What attracted me to the 780 is that even the starting load shows good velocity. I've got enough to last me and maybe my son too when the loads I gave him run out.

IF real life tests hold up to Alliants claims, RL 16 looks to be the answer with 130s. 3100-3200 with temp stability and copper fouling resistance to boot.

Shot the .300 Weatherby today with a couple loads of R23 and R26., both under 180gr Accubonds

At least in my rifle, with these lots of powder, there isn't a heck of a lot of difference in burn rate. 82gr of R23 ran about 3180 fps, and 85gr of R26 went about 3280, with one reading at 3303...which may be a touch on the warm side. Both were sparked by Federal 215M's.

Starting from a stone cold barrel, the first shot from the R26 load was right where I wanted it. The next two went about 4 inches higher

Let it cool off for an hour and repeated it with the R23 loads and it put 3 in an inch, and held zero nicely. Think I'm gonna tweak the powder charge a little and see if they tighten a little more. I'd be content with something real accurate in the low 3200's...

And next year, send to Pacnor for a new barrel

You guys test it out on the AI yet?

Anyone have the Litz G1 BC for the .277 150 gr partition?

When did Winchester axe the 780?

I still have some. Made a few good loads with it too.
