Thread: More 270 Win Loads

From what I have been told it is temperature sensitive. Also the load data I used was derived from the At 2213 SC load. Superformance is rated one slower burn rate than 2213 SC so if you load as for 2213 SC you should be fine. As with any reloading it pays to work up to max loads.
Superformance should work fine in any caliber that uses 2213 SC but just be aware that summer temperatures may rise your pressures. Should work well in 270WSM.
