G'day @Doon 57 of superformance gives 2990 out of the 20. 57.5 of Rl26 is 2950. Barrel is 8 twist.
Watch this space, I reckon I have a just as accurate load @ avg 3050fps. Just don't want to jinx myself until I have given it a second test.

@Doon I went straight to 57 grains as I was given the load. I believe that it is good for the 140s and should give you 3050fps with them.
I wouldnt bother going a higher charge as this gives me a sticky bolt lift. Messing with seating depths will give you different velocity but pressure seams consistent.
Let me know how you get on
@Gkp Did some ladders today with SP, 129sst had a good node of 2994 with 56.4 56.6 grains of SP, 140 SST was 2958 WITH 56 grains of SP.
57.2 grains of SP with the 140 ELDM stiff bolt lift.
20'' barrel measured using magneto speed v3
Gidday mate. Are you using large magnum primer with superformance or large?
I use federal 215 magnum primers in all my large rifle caliber's.
I know@Kelton is using RL26 and the 156 Berger in his 6.5 SAUM and I've just given him some 142 LRAB to try.
I'm using them in my .260 and have shot about 4 deer so far with them, the last was a big red hind at 200 yards with a less than ideal shot way too far back and I thought it would mean a long tracking job.
It ran into the bush and about 30 second's later it came tumbling down the slip.
The internal damage was massive, so I'll keep using them for now.

Im getting 3036fps out of my 20inch Hardy carbon wrapped barrel with 56.5gr of superformance pushing a 143 ELDX. RL26 shot just as accurate but it was slower If I do my bit it will shoot .3moa all day. At 600 yards 4 different shooters fired 5 shots between them and the group size was 3 inches. Two of the shooters were novices.
there are only two things guns fear
rust and politicians
@Taupohunter I got some 143's on the way. Would you mind telling me your COAL for this load please
