Hello
What powder would you choose that looks like a Reloader 26?
in Spain we only have available vihtavuori and reload Swiss

It doesn't list rl26, but I'm guessing it's near rl25. N560 or n570 may be close. The 5 series of vv have nitro glyrcerin added so might get a little more velocity with it.

Did my first testing with RL26 in 6.5 Creedmoor today. All shot out of 26" Shilen w/ Magnetospeed. 80F.

Got some light ejector marks on the Hornady brass on the last couple charges on the high end.

2.880" is about max length for my AICS mag unless I remove the spacer plate.

The 210 primers seem to flatten out quite easily, even with lighter loads. I think I will try CCI 200's next time.

46.7g in the Peterson Brass was at the bottom of the neck.

Barry, are you approaching pressure in the Peterson brass or just not able to get enough powder in the case due to internal volume? If so could it be settled with a drop tube or the electric toothbrush trick to get more in there? Without the ability to get enough powder in there a lot of the SRP advantages go away. Maybe a CCI 450 primer? Or if none of that works I guess it would be a faster powder than RL26.

Thanks for posting your results.

Yeah just ran out of room on the Peterson brass. I will try the toothbrush and the 450's. I will also try the 147's in the Peterson brass since they need less powder anyway.

I want to try out the SRP in my 6 Creedmoor, probably Alpha or necked down Lapua. If the cases are too small to get enough powder in there, it kind of defeats the point.

With the 450's and peterson brass in my .260 AI, I noticed about 40-50ish fps more than with BR-4 primers.

Three different 6.5's, 46 to 47.5 gr re 26 with 142 Sierra MK 2937 FPS with ES 13 and SD 5.6 with five shot group .45 to .65 at 100 yards. Drop down to 45.5 gr to start with 143 ELD-x

Hi all
A newbie here from the bottom of the world.
Thanks to you all I'm learning a great deal about reloading.
I have a 6.5 Creedmoor and am loading 143 ELD-x and 140 ELD-M using RL26
I have found a lot of data posted here from QL for the 143 eldx and 147 eldm
Could I beg a favour from the QL wizards here to run me some numbers on a load for
the 140 eldm.
Barrel length 24"
RL26
CCI250 primer
Hornady Brass
Seating depth 2.840
trim 1.910
Many thanks in advance

46.7 grains of RL-26 in a Peterson SRP case with a CCI 450, 2.901" (.040 jump) runs 2730 in my 20" barrel Tikka, in the .2's or .3's in a 3 shot group. This powder is magic.

What bullet?

 

[Hiwayman92]

143 ELD-X. Oops I missed that in my post.

Could I get a starting point to work from with rl 26, Hornady brass and 140 berger hybrid? I will work up from the start point. Thanks.
