I'm surprised with those velocities out of a 27" barrel,
I do wonder if the powder choice would be different in such a long barrel like that.
Alliant's website give really good velocities with the A-max out of a 24" tube like mine.
The one problem I had with 2225 in the last load was I couldn't fit enough powder into the case, It was pretty chocker with a large amount of compression and I reckon I never would have been able to get pressure signs. the powder is just too fat.
