Thread: RL26 loads 7mm Saum

Morning all
Just got my mitts on the magic powder I have been reading about for a couple of years!

Got it from reloaders supplies fyi.

Would appreciate advice on loads for both 162 and 180 edlm please?

I am using necked down 300saum norma brass and fed 215s

Cheers

@Kelton will be able to give you some good data.

Scratch the 215 and go 210 and if you only go a pound I wouldn’t bother mate just use 2217 but other wise what’s the rifle information standard chamber or longer throat I’m running and il have to confirm when I get home a .145 freebore loads both seated to 2,935 63.6 for 162-168 and 62 for 180 2950 2920 and 2900 fps fed 210s and Adg brass

Run 162 ELDMs in my SAUM, RP brass, COL 2.905 & around 63.0- 63.5gn RL26 for 3000fps in 22in bbl. But work up carefully
Norma brass is usually thinner/lighter than RP (more case capacity) so you might be able to go slightly higher?

That is a long coal so you should be able to use all my loads provided safely 215 will be fine

Mag fit at the coal which is handy - gave them a dummy round with a 175edlx seated out that still fitted in the mag.

Thanks chainsaw will start lower and see how i go.

Iv found inch’s of barrel more beneficial in saum than oal 63 is a safe start point as is 62 for 180 keep us posted

It's amazingly how well the saum goes with a short mag length aye. Most magnums hate these new long pills been stuffed right down into the case but not the little ol saum

Iv seen no advantages to a long action yet when it comes to velocity all finding the same pressure

Rounds to test loaded and registered for the local NZDA rage for next sunday so will see how it all goes.

My load was recommended by @Kelton

168 VLD with 63.6gr Rel 26 in ADG brass. 20” barrel for 2900 fps. I started with 215s but changing to 210s as he mentioned was an absolute game changer, definitely do it if you can. Mine is a true flite barrel too

I'm 64.2gr rl26, with 168s @ 3053fps

I'd be throwing those 168s with rl17! You prob have some.unburnt powder from a 20" with 26
