yeah I forgot there is some data for the RL26 and 270 weatherby on alliants site. Not anything remarkable because like John said the burn rate is faster than I assumed which was thinking it was as slow or slower than RL25. IMR 7977 might be a good choice with no manufacturer's data for it as well as RL33 with out any data published for it either.

It sounds like imr7977 is real close to H1000. Not sure how RL33 lands in the spectrum.

No idea on 7977 but R33 should work as it does in the .257WM and .264 Win. It is closer to Retumbo than H1000.

R26 is almost the same as 7828 and the old slower lots of MRP.
R26 gives me about 60 fps more in the 7RM than my old H870 load with 160s.

I had picked up a pound of RL26 a while ago and finally got out to out to try it in a TikkaT3 (22" barrel"). Velocity results are similar to others.

65deg
150 partition, RP brass, CCI 200, RL26
60 gr: 2937, 2936, 2933 - 1.21"
60.5gr: 2975, 2975, 2977 - 1.24"
61gr : 2999, 3004, 2998 -1.22

I was impress withed how consistent velocity was shot to shot. Usual load is 57gr h4831sc at 2820fps with .8 MOA groups. Going to play with seating depths to see if I can get RL26 under 1". Pretty good velocity improvement but now I have to wait for a cold day for additional testing

I did some more shooting yesterday with RL26 / 270 Win / 150 NP's / 22.5" bbl'd Kimber 84L MT

I went to a deeper seating depth (.050" off lands rather than .020") and groups shrunk nicely.

58.5 RL26 / WW Brass / Fed 210M / 2,991 fps / 1.160" 3 shot group with two close and one out.
59.0 RL26 / WW Brass / Fed 210M / 3,016 fps / .530" 3 shot group.

I'll keep playing with it and will also try it with 150 NBT's which this rifle really likes.

Dang, that sounds pretty good. Especially in the way you have your rifle set up, that is an excellent combo.

I'd have no problem with your second load running 3000, and a .53" group. Simply great! I really need to play with mine...

Ok after seeing all these great results using Rl 26 in a 270 I had to try it in my 270 Gibbs with a 25 inch barrel. Starting at 60 grains here were my results with the nosler long range accubond.
60 grains 2805fps
61 grains 2875fps
62 grains 2945fps
63 grains 3012fps
64 grains 3085fps
All loads showed no sign of pressure and primer pockets were still tight. I'm thinking I'll try 65 grains which should be over 3100fps. If it shoots well it sounds like a great load.

Mule Deer, would RL-26 be of any use in a 7x57 with heavy bullets?

Thanks, Ron

It might work. A lot would depend a lot on how far out the bullets could be seated; many 7x57's have the traditional long throat, and if the magazine's also long enough it would probably do pretty well with 160-175's.

Thanks Brad, that's promising. Filing for reference.

IF I can find some Rl 26, I'll do some testing this Winter/Spring depending IF/WHEN I find it.

Has anyone tried RL-26 and the 160 gr NP in the .270 Winchester?

Wow. Very interesting thread. Been considering another rifle in .270 Win. and this "tilted the scales" in favor, for sure.

I have a batch loaded up if it ever gets above zero and quits snowing I will get out and test them.

Same here!

It'll probably be April before I can get a chance to chronograph my loads but they do group well.

60 Grs RL26 under 160NP......020 off lands.

JB- forgive me if anyone has mentioned, not read every posts here, but it might appear 26 might show gain over 22 in a Swede with 140s. Any change you still have one and/or worked with it in the Swede?

Impressive speeds in a 22" - I dropped a CO Mulie near 300 yds, 150 PT went frontal just to the side of the throat, nearly exited, he want about 30-40 yds. 24" bbl - had 52/IMR4350, another half grain more was hot in this rifle.

2850 was MV, so no doubt H4831 would net another 100-150 potentially but R26 puts you in 7RM territory.

I was wondering if the Swede might benefit, possibly the SA 6.5 as well, like your 260.

I ran some 26 in my Swede with 120 Northforks and 130 Scirocco and Accubonds. The 130's were in the 2975 range and I never pushed them beyond that.

The same rifle does about 2750'ish with 7828SSC and 140 Accubonds. I plan to try a little 26 to see what happens.

65BR,

I haven't tried 26 in the 6.5x55 but probably will when I get some "spare time," which has been scarce lately!

I'm going to go all the way out to the end of the limb & make a real SWAG that it's highly likely that any thing that '22 works well in will likely benefit from '26. crazy

I thought that 26 was a temp-stable replacement for RL25? Or do I have that wrong?
I used to run RL22 in my M70 6.5X55 and it did well with 140gr partitions. I am curious to see what 26 will do also.
