Thread: superformance powder load data 260

i know a few of you have found it good in your 260 me and a mate are going to shorten our barrels some what and will need to go for a complete new load
we have been reading about this superformance powder and how good it is for short barrel 260's but haven't found any load data just wondering how you work your loads out
guessing you started by looking at 6.5 creedmoor data and starting with max load or close to creedmoor load in your 260 since 260 has a little more case capacity???

cheers in advance

Sorry can't be much help as mine is 22" and a .260AI Brads has a 20" and uses it with ELD-X 143

@BRADS what data did you use to work out how much to use as a starting load?

I just need a safe way to sort a starting load out then I can work from there

I dont like these threads mate, the guys I trust said start at 45 and work up.

all good mate

I would start at 43 and work up.
My Ackley shot 47gr with no pressure signs in a 24" barrel.

ok sweet I think we will be trying 123's so from experience will need slightly more powder??

R93 has to run reduced loads so he doesn't blow the arse washer out of the blaser.

Yeah you could start higher with them. As Brads said 45gr would be a good start point with the 123.
Reminds me I must try the 123 in my Ackley. Been meaning too for ages.

That's actually the real reason I can't come to the memorial shoot. I run out of washers.
Probably would still win it if Dunners lent me his .22😆

What was the velocity on the 47gr, as a matter of interest?

Not as good as RL17 but good ES.
2950ish with 140, 143.

2990 with 129gr hornady interlock.
