Looking at using this in 260 and a Swede.
Looks to be in the middle of IMR4831 and 7828sc in both burn rate and load density.
Given the lack of data for superformance, would it be reasonable to start out middle of the table in either of the IMR powders mentioned?
Appreciate your thoughts.
looked at using it awhile back for mates .308...we nearly came to blows over it as I wouldnt load as was asked to as wasnt prepared to take risk when no data was present.....from memory its said to be good in .308 with heavy weight bullets.....so be interested to know how its going to be good in .260.....
where its good its very good but the band of goodness seems to be slim.
Yeah, I'd hate to walk in 4gr over max due to my extrapolations
RL 22 data seems pretty close

that SHOULD give you a couple of starting places.
Plenty of info online, works real well in my 6.5CM, bit more speed than with 2209 and less pressure signs, tried it in my 270, worked ok, but I just went back to my normal load so I could use the SPF for the 6.5.
Ok, ill have another trawl.
In my experience it wasn’t overly accurate and speed wasn’t great. I worked between 43.5 to 47.0 over a reasonably long time. With 143.
Currently using R17.

In my Swede I got 2600 fps with 45 grs of Superformance, haven't tried to go further but there is room to move. I like it in my 270 Win with 57 grs , speed is right up there and accurate in a Tikka with standard length barrel.
Hodgdon website say 40.7 starting and 45.3 max for the 143gr ELD-X in 260.
Powder isn't listed for 6.5x55.
Thanks, must have been a different part of the site away from my clicker:thumbsup:
Seems worth chasing over the w760 I'm currently using so long as it shoots well. IMR 4831 is another powder in looking at

Think I will try some IMR4831...oldie but goodie
I've used it in my .260AI , .260 and a 6.5 Creedmore all the .260 versions are in the 47 grain area I started at 45grns but mine are seated out long 20 thou off the lands and are running at the top end I'm getting over 2800fps with the 143ELDX with all three .260 although I do use RL22 in my Forbes.Quote:

Yeah, that's the other part of mixed reviews that got me interested:thumbsup:
I was hurting brass at 47.0 and I’m not into hurting Lapua so I moved on. No signs with R17, no pressure and accuracy is ok.
Am interested in trying R16 next time failing that I’ll be back into 2209 or improving it just because I can and they look cool [emoji41]
I tried RL16 hit pressure and compressed loads it wasn't any where as good as Hodgdon superproformance powder or RL22.Quote:
