Thread: 270wsm rl26 145g eldx my experience

Hey team, this is not a how to or a cry for help just want to share my experience with developing a load for my Sako A7 270wsm.
I bought the rifle in good second hand condition and it came with load data for 130g ssts that were laser accurate and plenty fast at 3200fps.
I'm not a fan of them so set about developing a load with 145g eldx, which I had great success with in my 270win. I spoke to a good mate of mine who also shoots 270wsm with 145g eldx and was swayed by his results with RL26.
He was getting laser accuracy and a blistering 3300fps, granted in a custom built rifle with a longer barrel.

watching with interest.....

I was hoping for accuracy and around 3200ish fps but I got too caught up worrying about the speed. Accuracy is way more important at the ranges I want to shoot at and I can adjust my drop charts accordingly.
I was a little frustrated that my wsm load is only around 100fps faster than my old 270win load but in hindsight the wsm is doing it with a very mild load and the win was certainly getting up there towards a warm load.

So after spending a bit of time trying to source the unicorn dust that is RL26 and then finding a way to get it half way down the south island, I was finally ready to start some test loads.
I harrased a few good buggers with vastly more experience than me about where I should start with my ladder and settled on.
64.5 - 67.5 going up in .5gn increments
I shot 2 at each load and got some great grouping but nowhere near the speed I hoped/expected and no pressure signs.
So I went home and made another ladder from 68gn-69.5gn again in .5gn increments.
Went back to the range and set about firing off the rest checking carefully for pressure as I was now getting up above book max.
I hit pressure at 69gn and topped out at 3250fps with that load but it and the 3 loads below it didn't group well.... Even with only 2 rounds per load.
I got so caught up worrying about speed I forgot that I wanted a laser accurate load good out to 600 yards.
I was so focused on trying to justify the hotter faster loads and how I could improve or justify their lack of consistency that I nearly convinced myself to overlook my lower speed loads that were laser accurate and speed consistent.
I am now at the stage where I'm going to make up 6 rounds from the 2 loads that gave the best accuracy and most consistent speed.
1 load at 3030fps average

1 load at 3060fps average


This is where I hit pressure at 69gn


The 2 above groups were at 65.5gn and 66.5gn and only 2 shots but both showed speed variations of less than 15fps, so back to the range tomorrow to do a couple 3 shot groups with both these loads to check accuracy and get more speed data.
Whilst 3300fps would've been nice even at 3030fps it's more than enough to get me out to 600yards. Moral to the story don't get caught up chasing speed.....

ok just answered it in crisscrossed postings..2900ish...not shabby for std case which you could as you say just adapt drop chart a little for....

Was getting 2930fps with the same 145gn eldx using 2213sc powder in my 270win

so now I HAVE to ask....what speed were you getting with std .270 and that projectile???

Might try adi 2225 at some stage but if this rl26 load proves accurate and consistent it wont be for a while

Interesting, I would have thought RL 26 would have done better in the accuracy department. Have you any Superformance to try ? It should work as I would presume AR 2213 SC will work in the 270 WSM so Superformance sits at a similar burn rate. Just be aware that Superformance is a bit more temp sensitive than ADI stuff. I still can't believe the velocity my 270 win gets with Superformance, I have chrono the load a couple of times and they still run at around the 3130 fps.
Like you said speed isn't everything but accuracy is so it's not a major problem to have to dial on a few extra clicks for the long shots.

I'll play with other powders if rl26 continues to be difficult to obtain, was thinking 2213sc and 2225 would be ok haven't tried superformance either but would give it a nudge too.

It's worth a try you may get accuracy and speed. AR 2217 might be ok too.

My most accurate load in my 270wsm with 145eldx is 69.5 grns 2215. 3140fps from 22" barrel. Grouped very well.

R26 works best for me with 127grn LRX Barnes. 3270fps from 22" barrel. Fantastically accurate. This has been my hunting load but they don't leave much of a blood trail which I like.

Am currently fiddling with R19 (which is available) and 130 grn Federal trophy bonded tipped. 3330fps. Have to accuracy test them properly. Am thinking that they might expand a bit better than the LRX but will see.

Some pics to show what I'm talking about.
You can just see the faintest mark on the shoulder, no other marks anywhere on the chambered case




Pics of case measurements





The case coloured in black has now been full length sized in my Lee sizing and decapping die twice and is still way to tight, its got me stumped.
Below is a chart showing case dimensions note the full length trim and max measurements and the "F" measurement which is base to shoulder
