So - I find myself with a few canisters of Superformance, got plenty of other suitable powders for my needs, this stuff is unfamiliar to me, do I bugger round with it or store it for a rainy day? Running .243 for just about everything, and about to start load development for my new .257
Anyone run Superformance in either of the afore mentioned cartridges? with what pills and results?
swap it for something you do know about...where its good its great,but it has narrow band of usefullness. big heavies in .30/06 being one where its good... its a funny stuff,some swear by it,others swear at it.
I load it in a number of cartridges .243,.260,.270,300wsm and Creedmoor.
It gives awesome speeds with very low SD.

Just wish there was a reliable supply in NZ but that is wishful thinking about any components in the current climate :psychotic:

Nothing down here :psychotic:Quote:

It's a slow burning ball powder, so meters well.
General rules for ball powder, don't ever run compressed loads, your ideal charge weight will be quite narrow, don't run small rifle primers in a 308 family case with it or you might get poor ignition/hang fires.
Lack of load data is down to Hornady, not Hodgdon, same as the LeverEvolution powder.
I was stoking 46gr into Lapua brass, cci200, Barnes 85gr TSX for 3200fps from 18.5" barrel. Accurate and kills the shit out of things.

You would make Te Tawa's heart sing with that praise of that pill. Look on Barnes official website. It is not a pretty picture much like Sierra which has bought Barnes. Lotsa criticism in USA about poor manufatcuring of projectiles considering there is no war effort displacing demand. Sierra at top of pile. Gunworks websire records .224 availability of Sierra in late November.Quote:

2217 should be here pretty soonQuote:

Finally got to the range to give the superformance a whirl and looks like I have something to work with. Loading 162 ELDM in new 300 Saum Norma brass necked down. 5 loads starting at 62.5gn at .5gn increases to 64.5. From a 20" barrel measured with a magneto speed results were:Quote:

good start pretty pleased with 2950 from 20" :)
Superperformance is good but it's really hard to get published data on it, although there is some around now. It's also not listed in quickload unless has been recently.
The other thing is because it packs in so tight the extreme performance loads are quite a bit heavier than standard powders that you would load for a certain cartridge so you are often going into uncharted territory, so need to have your wits about you.
I think that's why most people just can't be bothered.
One thing it does do that might add to being very accurate, it meters amazingly consistent.
