I tried their supposed max load in my 22-250.
Well that was UNIMPRESSIVE!!!
I used a HOWA 22-250 stainless with a 24 inch barrel. This rifle has previously shot very good groups with H-380 and 52 grain match bullets. (less than half inch)
With this new can of Superformance powder I went right to the max load listed by Hodgdon. 43.0 grains which is right up to the bottom of the neck. I used Remington once fired brass and Federal 210 primers.
I used three bullet types today. Sierra 60 grain hollow point flat base. Hornady 55 grain soft point spitzer flat base and Remington 55 grain FMJ-BT . ALL loads had 43.0 grains of this new powder.
I used a COL from previous loads that this rifle has liked in the past.
60gr HP (col 2.380 in) Vel: 3,521- 3,499 - 3,590 - 3,521 - 3,560 - 3,546 - 3,511 - 3,547 - 3,535 fps (2 inch group)
55gr SP (col 2.350 in) Vel: 3,493 - 3,544 - 3,589 - 3,549 - 3,516 (I inch group with a flyer out to 2 inch)
55grfmj (col 2.370 in) Vel: 3,616 - 3,535 - 3,555 - 3,533 - 3,563 ( FOUR INCH GROUP )
All cases had ringed primer strikes and sooty case necks. The bore was also pretty dirty.
Hodgdon claims they obtained 3,700 fps with this same load.... I call B.S.
