I don't have quickload but I have several .270 win's, a few pounds of Reloder 26 and the 129 gr
lrx's.
I did ask for a little assistance ( everyone is so helpful on the World Wide Web) and it showed a muzzle velocity of 3300 +
Pressures maxed out of course but still under 65m.
Can anyone corroborate these sizzling numbers?
In the name of science of course.

Back when I had r26 I worked up a load with 130 gr Interbonds that was a little over 3200 and grouped very well. This was with a 22 inch barrel. I prob could have went a little higher but the groups opened up.... so its prob possible.

I use about 61.5 grains of RL26 with the Tipped Trophy Bonded Bear Claws in a 22" P64 270 Win. I get an easy 3150 from that rifle. Not sure if I could've ripped them faster, but 3150 is easy peasy with that combo. Right now, it is one of my favorite combos in a 270 for deer hunting.

Running 61.0 grains in W-W cases with WLR’s for spark. 129 LRX’s come out of my 22” Fwt about 3100. This is the load I’m taking mule deer hunting in about a month.

Nosler brass and 61.5gr of RL26 with a winchester large rifle primer is getting me 3150 out of a 22” barreled Remington 700 titanium


Oh, and believe it or not, deer bite. Fairly hard.

Barnes factory lrx ammo is 3140. I verified it out to 425 and seems to be right.

Here's a thread I started a couple years back. I stopped at 60g because velocity and accuracy were very acceptable. This was using the 130 TTSX but I bet you could get close to 3300 without excessive pressure especially with a 24 inch barrel. Biggest trouble is finding RL26 or almost any Alliant powders around here....

Very interested in this thread! I have a 270Win and shoot the 129gr. LRX and a 243Win and would love to have 1 powder to load both cartridges! I’m currently trying to do it with IMR-4831 but have yet to shoot my loads.

Having burned through 10+ lbs of RL26, much of it In four different 270’s, three w/22” bbls, one w/25” bbl, 3300 fps with a 130gr mono is almost certainly well over 65k.

The mystique of RL26 continues.......

RL26 makes my 270 sing with 130’s and 150’s. I tried many other powders, including the old standby H4831, nothing beat RL26 from an accuracy or velocity standpoint. I have also heard it does very well in the 243. There was a thread on here a while back with a lot of folks recommending RL26 with either the 95 Gr partition or ballistic tip in the 243, depending on game hunted.

RL26 does indeed work with 243’s and 100gr bullets.
I haven’t tried 95gr bullets cause RL26 is intended for overbore cartridges with heavyish bullets. Although Nosler treats the two bullets the same in their load data.........

I'm getting 3278 with the LRX using 73 grains of RL26.

I'm also shooting a .270 WBY! Getting to 3300 safely with a .270 Win would seem unlikely...

thanks for posting this 62 ish grains of RL26- 3300 fps. I put RL 26 behind 130 grain Cutting Edge mth's and noted 3230 fps...no reference to the group size. The rifle a Remington 700/ 22" barrel/ easy extraction and no excessive pressure indicated on the primer. Older data

I’m getting 3196 fps with a Nosler 150 LRAB in my 270 Winchester just using the book maximum charge with 210m primers. Tight groups too, but it kicks like a 7mm mag.

Of course I cannot do pressure measurements but extraction is smooth, primer pockets stay tight & no excessive case stretching. After market 25” Benchmark barrel gives me the edge over the 22” factory barrel guys

RL-26 is a great powder, but in my experience the .270 Winchester runs out of powder room before 130s can be pushed any faster than they can with several other powders.

After the range session last Sunday it’s clear IMR-4831 is NOT going to be my 270/129LRX powder. I was getting just over 3200fps with 58.0 gr. but my 5 shot group measured 1.6”. However, 55.5gr of IMR-4350 and the LRX clocked 3165fps and had a 5 shot group of 0.89”! Close enough for me! Since RL26 is pretty much unobtainable and I have 2.5lbs of 4350, I’m satisfied with that load and another 35fps isn’t going to matter one bit! I may still try RL26 someday if things get back to sorta normal, but for now I’m good!!

Shoot straight!

I am getting around 3200 fps in a 24" barrel and 61.5-62 grains R26 and I am probably too hot. Quickload says R26 is slower than R25 so the numbers will be off more than with properly calibrated powders in QL. The 3,300 fps range requires putting the pedal to the metal even with the WSM, R26 can do it but I don't think it is the best powder in the WSM. I am running R26 with the 140's at 3,200 fps. at a max of 69 gr. which I bet will be revised downward if they re-test these loads.

Nosler WSM data goes almost up to 3,400 fps but Barnes barely reaches 3,200 fps., which the 270 Winchester can and has been doing for a long time.

Sorry I missed this one.

Alliant lists Reloder 16 as getting the highest velocities with 130-grain bullets in the .270 Winchester. The latest Speer manual shows 26 getting the highest velocity with 130s (3171 in a 24" barrel), but that's only by 5 fps over H1000. Both RL-23 gets 3113, and in my experience is more temperature resistant and than 26. I don't know why so handloaders assume 26 MUST produce more velocity with 130s than anything else, just because it does with 150s--especially since the case needs to be really full of 26 to get top velocity with 150s.
