Here's some info. The search feature really taps into the knowledge that so many here, have.

While sighting my rifle in last week we all got to talking about the 6.5 cal and how well it has done and one person said he shoots Superformance in 6.5 creed as he gets much more velocity.I hope to have a 260 soon and am just thinking ahead.
I was just wondering if other bullet makers have load data for Superformance powder because the only loads I see is in the Hornady reloading book for Hornady bullets.
Just curious,

Thanks Muddyboots I'll keep this as a reference.
In some loads it seems to give higher velocities so I will keep this in mind.
Thanks

Just keep in mind not to empty an off the shelf Superformance round and try to match that weight. What is in the OTS ammo is not the powder they are selling for reloading.

I have 9 lbs of superperformance for $180 shipped.

Superformance is not a normal extruded powder, it is spherical and not stick shaped like traditional powder. The pressure curve is different and that's why it acts different. Because of this Hornady, the drive behind it, is probably the only published data around. I always stayed away for that reason.

There is a guy on savage shooters that did a bunch of pressure testing with it but I won't get into that. @Darkker may chime in.

I use it for my 6.5CM with 123gr SST's. I get ~2950fps in a 22" A-Bolt II with very good accuracy results. I've read that there are some potential issues with velocity variations due to a secondary ignition possibility but I've never personally experienced that. I've tried it in a couple different bullet types/weights but it didn't do as well as some of the other well known powders for those particular combinations. I do plan on trying it with some AB/BT in 140gr to compare with what I'm getting with RL26 but that will be after hunting season when I can fool around a bit more.

I use it in my 25 wssm. Fill density is fantastic and it seems to really be a linear powder for how oddly shaped it is. I did try it on a 375 rum with average results.

I use in my 22-250. You get great velocity and accuracy. It also throws so well I don't weigh those charges.

I use it in the .260 rem with 125 partitions and 130 Gamekings and Accubonds and it has been fantastically accurate and fast and I have not had any pressure issues. I met my velocity goal and exceeded my accuracy goal and stopped working up. I love it. I just used Creed data to get started.
