My Lyman 50th Edition Reloading Manual says that Hornady made this powder for their Superformance loads. Has anyone tried this powder with a 6.5 Creedmoor and had any luck with it ? Just looking to see if it would work as good as H-4350 and give the same or better groups. I have not used any of the Superformance factory ammo.

.8 Moa at the moment using 147 grains and magnum primers in a Semi. The velocity from it is fun as well. ... makes a decent thump of noise indoors, and pisses anyone in the room off quite well. mine is super clean, but I under load by a lot.

Better groups, not really. Faster, yes. An under loaded Superformance case seems to act like an overloaded 4350 case.

Hornady has/had? a 6.5 Creedmoor load with 120gr GMX and Superformance. roughly 2900-3100fps. Not very accurate out of my factory remington. roughly 1.5" groups @ 100yards.

I've used a couple jugs of it in a 7mm wildcat similar to the 7mmSAW/ 7mm-08 Ackley; no 6.5 Seymore experience. Dense powder, slower burn rate than H4350, good velocity, low SD/ES at pressure, meters great, not especially temperature sensive that I've noticed. I did try a freezing/ambient/hot loads over a chrony and wasn't too concerned with the outcome but lost the data somewhere. It does burn pretty dirty for use in suppressors but I never noticed any excessive carbon fouling of the bore/throat.

There is noticeable lot-to-lot variation in my experience.

Just keep in mind it's not the same powder Hornady uses. Theirs is is blended by the train car load and has different characteristics than the bottled stuff. Do not expect factory performance from it. I've used it for several calibers and remain unimpressed at best.

ok so here are my results with super performance. keep in mind this is my first batch of reloads ever, i used coal not ogive, and i probably mucked something else up that i dont even know.



all are 3x shots as i was expecting worse results and was kind of hoping to just find a node and then reload 5x groups in those areas.

first and last group is hornady factory 147eldm loads, last group is a 5x group
everything else is my loads all 147 eldm

factory/ 2679, 2662, 2692 / av 2678, es 29.61, sd 15.03 / group .758"

41.5 / 2535, 2532, 2523 / av 2534, es 22.83, sd 11.57 / group .412"

41.8 / 2546, 2532, 2523 / av 2534, es 22.83, sd 11.57 / group .771"

looking at the results im thinking reload 5x in the second green area. ive seen recommendations of .1 grain increments. possibly between 43 and 43.5, thoughts?

also as far as speed there were no signs of pressure, im thinking i should keep pushing and try to find another node or 2.

also is there any benefit to staying at a slower node besides barrel life, and maybe less adjustments for ballistics. once you have your dope chart you should be set no matter the speed right? less wind calls?

over all im happy with the results, should i be?

I've been unable to find data for Superformance powder at all anytime recently. I looked in Hodgdon Annual manual going back to 2007 but didn't see data in any cartridge I load for. Is this powder still out there?

So would you guys think use max load from the bullet manufacturer or the powder manufacturer. I'm already over max according to hornady. But no heavy bolt or case head swipes.

Just found the hornady data, I was using the Hodgdon data before.

Tried it in 6.5 Remington Magnum and .30-06 Springfield. Don't have a velocity on either, but accuracy in the 6.5 was just so-so; terrible in the .30-06. Got swipe marks with the load in the .30-06 at 88 degrees, tried again on Wednesday a 53 degrees - no swipe marks, still 2 inch groups. I got a larger than usual fireball and blast. I'm not impressed with this powder for either of there cartridges.

Good Luck

Superformance is a fairly new powder and Hornady and Lyman both have loads for it in the 6.5 creadmoor. These are the main two loading manuals that I use and right now the 6.5 Creedmoor is the rifle I am working up loads for, but I am sure there are other calibers that use this powder.
