280 grain Swift A-frame:
Used 56.0 grains of RL-15.
Seated to 2.860 col.
CCI-200 Standard primer.
Slight roll crimp into the side of the bullets since the cannelure was inside.
2,420 fps with only a 5 fps spread.
3/4 inch group.
Oddly enough the 280 swift is slightly shorter than the old 275 grain Barnes bullets.
They are rather pricey
